How to make a tie-in into a water pipe made of metal or polymer? Methods for inserting pipes into an existing water supply Clamps for connecting to a water supply.

There are often cases when it becomes necessary to expand the water supply system in order to make it possible to install plumbing equipment. It may also be due to the need to install an additional circuit. In any case, such actions should be correlated not only with safety, but also with a certain order of work. In this article, you will learn how to crash into a water pipe.

The characteristics of the main water pipeline are as follows: the laying of such a pipeline is carried out on the main streets, pipes with a diameter of 100 to 2000 mm are used. To implement the insert, one of the two possible options for executing this task is required:

welding- a thread is welded, which is necessary for the installation of a crane, which is used to connect a pipe going to a particular house;
clamp- used when there is no possibility of blocking the flow of water.

The depth of the line determines the location of the tie-in. If the main pipe is at a decent depth, then the tie-in is made in its upper part, and otherwise - with a branch to the side. Let's take a closer look at the mentioned options.

welding method

When using this method, it is advisable to first turn off the water supply, and then proceed to a direct tie-in. Why you need to burn a hole in accordance with the diameter of the thread, which then needs to be welded.

At the same time, the process of such work does not always look exactly like this. In some cases, tapping into a water pipe is carried out without shutting off the water supply. This can be explained by the elementary absence of shut-off valves or by the fact that such fittings exist, but they are old, which does not allow them to be used for their intended purpose. In practice, the following set of actions is expected:

the place of the tie-in is selected, where the thread is welded;
then a full bore valve is screwed on;
a hole is drilled through the installed faucet, ensuring that the perforator is protected from water by a rubber or cardboard screen;
at the end of the previous process, the drill bit is pulled out sharply, and the tap closes.

Drilling should be done at high RPM, as this reduces the chance that the drill will jam. This tie-in method is problematic, due to the high water pressure in the main water supply. If the pressure exceeds 5 atm., Then it is necessary to refuse to independently carry out such work. In this case, you should contact specialized organizations, and not take the initiative.

Clamp

The option of using an overhead clamp, if it is necessary to tie into the line, is quite suitable when working with pipes made of different materials: steel, polypropylene, polyethylene, etc.

In practice, such a tie-in has the following procedure:

In the same way, a tap is made into a water pipe without turning off the water, but only if the pressure does not exceed 5 atm. To a greater extent, this method is suitable when working with a polyethylene pipe - a simpler drilling process. When the pipe and clamp are made of metal, there is no need to fix the clamp. As for the polyethylene pipe, this is not the case, which is explained by the presence of a large linear expansion of this product. This forces the use of epoxy to seat the yoke.

Insertion on a secondary section of the water supply

So-called secondary pipelines branch off from any central highway, supplying water to neighboring streets. The pipes of such wiring are mainly polyethylene, they differ in a smaller diameter - an average of 50 mm. Usually, taps are installed at the branch points of secondary pipelines, the overlap of which simplifies the work of inserting pipes, which is available using two methods.

First:

A trench 2 meters long is dug along the pipeline. This implementation of the problem is used mainly in relation to pipes of small diameter (up to 50 mm).
The pipe is cut.
A tee is mounted on the pipe, which can be welded if the pipe is metal, or simply fastened with union nuts if it is polyethylene, for example.

Second:

An overhead clamp is being installed, the factory samples of which are equipped with a thread necessary for installing cranes.
The faucet turns on.
A hole is drilled, which is done directly through the crane. This can be done without shutting off the water supply, since the secondary pipelines are characterized by low head pressure.

In the place where the insert was made, if possible, it is necessary to arrange a well. For this, a concrete ring or a used brick as a base is suitable, followed by closing the structure with a lid with a built-in hatch.

Insertion into a metal plumbing

When working with a metal pipeline, it is desirable to use a saddle clamp, which has several varieties. Immediately before mounting the clamp, the pipe must be put in order, that is, it must be cleaned of dirt and rust, if any. The design of the saddle clamp involves the presence of two semicircular parts, bolting and a shut-off valve with a hole that is designed for drilling.

The tightness of the clamp to the water supply is ensured by special rubber seals that guarantee the tightness of such a connection.

The procedure for tapping into the pipeline:

fix the clamp on the surface of the pipe;
drill a hole;
install the plug in the form of a screw intended for this.

It is also possible to use a clamp, supplemented with a valve. Here the order is the same: a hole is made, the drill is removed and the valve is closed.

Along with this, there is a tapping machine, consisting of a handle, a locking bolt, a drill mounted on a shaft, and a flushing valve. All these elements are located inside a metal case, attached to the clamp using a rubber seal. The use of this device makes it possible to produce a comfortable tie-in into pipes.

Insertion into a cast-iron plumbing

Drilling of cast-iron pipes, which are part of a pipeline that pumps water under pressure, is carried out using special clamps. These products differ in some design features and the use of bimetallic crowns. Such a tie-in should take into account certain nuances:

cast iron is brittle, therefore, when drilling, it is necessary to apply a small degree of pressure;
before carrying out work, the layer applied to prevent the appearance of corrosion should be removed from the pipe;
drilling should be done at low speeds;
excessive heating of the crowns should not be allowed.

When the compacted layer is removed, it is required to install a collapsible saddle where the tie-in is supposed to be. In this case, it is necessary to seal the junction with rubber pads. The drilling process itself is carried out using a carbide crown.

Tapping into a cast iron pipe is based on the following steps:

When inserting into a cast-iron pipe, it should be remembered that the saddle pipe must be installed so that its slope in the direction of the house is 2 degrees.

The saddle clamp makes it possible to tie into the water supply from plastic pipes without reducing the pressure. Such a clamp is created from the appropriate plastic, and its equipment includes a drilling mechanism and a heating coil. To ensure welding accuracy, a special bar code is applied to the clamp body. This tie-in method is used for pipelines operating at pressures up to 1.6 MPa.

The service life of the saddle clamp can reach up to 50 years, as it is resistant to corrosion.

Before tie-in, the pipe is thoroughly cleaned, and then a clamp is attached to it, which has terminals that allow you to connect a welding machine, which makes it possible to weld the branch by heating the spiral. A saddle equipped with a cutter and a valve also finds its application:

Installing a pipe on a water pipe using welding is a job for professionals. At the same time, you can independently install saddles on pipes made of cast iron and polymers, if the water supply is previously turned off. When tapping into a water pipe under pressure, the existing safety rules governing this type of work should be followed.

Permissive documents

Tapping into the water supply on your own site does not imply obtaining any permits. In this case, it is quite enough to make appropriate changes to the plan of the water supply system. The situation is quite different if you want to make a tie-in into a centralized water supply pipe. If you do this on your own initiative without obtaining permission from the competent authorities, this may lead to penalties against you. Such actions should be carried out only on legal grounds.

Also, such work requires some care, since damage to the water supply system can cause a serious accident, which will lead to the need for restoration work, the cost of which, as well as fines, will have to be paid by the culprit of the event. The tie-in to the main line for the purpose of organizing a diversion must be consistent with the precautions at each stage of the work.

The cost of tapping into the water supply

The price tag for a polymer clamp is 100–250 rubles. In this case, a fitting installed on a pipe with a diameter of 32 mm will cost 100 rubles, and for 75 mm fittings - 250 rubles.

The cost of a stainless steel clamp, supplemented with a flange outlet, is 9–10.5 thousand rubles. The scope of delivery of this equipment includes a rubber gasket and 6 studs that provide the ability to fix the staples.

Electrowelded saddles manufactured by the Italian company Eurostandard Spa, having a diameter of 40–250 mm, can be purchased for 25–80 euros. As for the cost of work, the average price tag for services of this type ranges from 2 thousand to 2.5 thousand rubles.

When assembling and connecting water supply systems or its discharge, it often becomes necessary to connect pipes, and it is better to do this without using a welding machine. However, not all home craftsmen are familiar with the specifics of such fine work. Do you agree?

We will tell you how to insert into a pipe without welding when laying pipe structures. In the article proposed for review, all methods of making connections for pipes from various materials are analyzed. With our recommendations, you will be able to create a strong, securely cohesive knot.

There are several ways to connect pipes to the main line without welding. Some of them are classified as one-piece, which is almost impossible to disassemble without destroying the pipeline. Others are detachable joints that can be easily dismantled and, if necessary, reassembled.

The choice of option depends on what material the pipe is made of.

Connecting pipes without welding, without having any special skills, is a feasible task even for a novice master; you just need to strictly follow the installation instructions

All pipe rolling is divided into two main groups:

hard - pipes made of cast iron, copper and steel;
flexible - products are made of polymeric materials (polypropylene, metal-plastic, polyethylene).

This separation is based on the need to use a larger engagement area at the moment of joining parts of polymer structures. For comparison: tie-in of metal pipes can be performed under limited conditions, using the minimum engagement area of the joined parts.

Insertion option with ball valve installation:

There are many connection methods that are a worthy alternative to strong and reliable welding. The main thing is to competently approach the choice of the best option and carry out the insert, strictly adhering to the technology.

Before draining from an internal or external water supply, it is necessary to purchase auxiliary parts and tools. Their choice is made taking into account the type of pipes from which the water supply is laid. This takes into account the operating pressure in the system.

The need for insertion into the system inside the facility or on the site arises when an external tap, plumbing equipment and household appliances are connected to the network. The procedure for cutting into the main network is carried out in order to connect a new facility to the water supply.

The principle of insertion into the system

Before starting installation work, it is recommended to coordinate them with the water utility and the local administration. If there is no central sewerage on the land plot, tapping may be prohibited. But in the presence of a septic tank and all established sanitary standards, it is possible to obtain such a permit.

To join the pipes, a special well is equipped. If the water utility prohibits tapping into an existing water supply, then the object is connected to a nearby well. But it must be in working order.

The process of tapping into an external highway is carried out using the following technologies:

using fittings that are installed on the pipe during installation;
fixing the outlet branch of the system if there is no pressure in the system;
the use of a fitting that is fixed to the pipe. Such a connection does not require prior shutdown of the water supply in the system.

Welding

Experts believe that the easiest way to tie into a steel external network is welding. A prerequisite for tie-in is the ability to turn off the water supply through the system.

Autogenous make a hole of suitable diameter. Then the pipe is welded, the valve is mounted. The last element of the system is covered in the process of further work. If the tie-in is completed, it will be necessary to restore the anti-corrosion protection.

If the pipeline is laid from polyethylene pipes, then welding work is not carried out. Taking into account the diameter of the consumable material, the clamp is fixed.

Installation of a branch pipe without blocking the main line

Tapping technology without changing the pressure is an efficient and productive technique. But before doing it, you need to consider:

dismantling of insulation and protection of the surface in the area of pipe drilling. At the same time, the diameter of the material with which water will be discharged is less than the parameters of the main pipe;
fixing additional elements of the network. A valve with a device for making holes is fixed to the flange;
if a steel product is used, then the clamp is replaced by a pipe that is welded. A valve with a cutter joins it. The completed seam is additionally welded;
the next step is to install the cutter of the desired size. If the hole is ready, the cutter is removed;
valve closure. If the tie-in is completed, it is necessary to restore the anti-corrosion coating, insulate the pipes.

Step-by-step tie-in to the internal network

If it is necessary to crash into an old steel pipeline, then the main method is to equip a branch by welding a tee. This will require a lot of work.

If a pipe made of plastic or its derivatives is connected to the main line, then you will need to cut out a section of the pipe, taking into account the size of the mounted tee. But when doing such work, there is an inconvenience due to the close distance between the network and the wall of the building.

A simpler method of mounting a branch is considered to be a pipe tie-in with a curved flange. A consumable with a branch pipe, the diameter of which corresponds to the size of the pipeline, is preliminarily denied. The segment is cut lengthwise so that its part with the branch pipe fits snugly on the pipeline as its other wall.

The previous workpiece is superimposed on the branch pipe with a hole. The place of fixation is treated with a sealant. The resulting flange is pulled together with 2 clamps on the sides relative to the pipe. Subsequently, the rest of the network is fixed to the branch pipe.

On the modern plumbing market, you can buy adapters, special saddles and other devices with which the insert is made (regardless of the conditions for laying the network).

If a saddle is used, the pressure in the system does not change. The saddle is a collar made of 2 parts. With the help of bolts, these parts tightly compress the consumable from 2 sides. A crane is fixed to the saddle with a special connection.

If the hole diameter is not more than 1/3 of the pipe diameter, then it is drilled with a special tool. He time joins the faucet. If the hole is ready, the valve closes, the device is dismantled. A drain pipe is mounted to the installed tap.

To connect the house, a saddle with a valve and a built-in cutter is used. For its installation, socket welding is required. A similar product is used for pipelines, the pressure in which does not exceed 16 bar. During installation, the line does not overlap, and when drilling pipes, there is no leakage, no chips are formed. The connection does not corrode and has been in operation for more than 50 years.

Punch methods without welding

It is possible to cut into the main pipeline without using welding. This technology is used by many specialists, since welding work requires compliance with safety rules. In this case, special equipment is required for welding. Welding work is considered complex and time-consuming.

From non-welding tie-in technologies, there are:

installing a collector is the best solution for a large private house. A compact collector system is also installed in the apartment. A water pipe is installed to the inlet of such a system. The collector has several outlets. Their number depends on the system model. The pipeline connects to any outlet. Adapters are used to fix the hoses;
installation of a tee - this tie-in method is used if a single outlet is provided. The water supply connection is pre-untwisted, and then a tee is mounted in this place. The pipeline is expanded or shortened by threading;
the process of cutting the pipe itself - the technique is optimal if there is no connection from the outside. To perform cutting, a grinder is used. A pre-threaded tee is installed;
the use of a thin pipe - a hole is prepared in the system, on which a sealant, clamp is fixed. Lag screws are used to mount the outlet.

Arrangement of a plastic and metal network

To enter the plastic system, you will need a piece of consumable material, a pipe of the appropriate diameter. At its end, 1/2 of the pipe is preserved, due to which the function of closing the tie-in points is performed.

A hole is made in the line with the diameter of the pipe. It is treated with a sealant. The flange is mounted on the pipe, and on the sides it is tightened with clamps until the hermetic substance comes out. Its remains are removed immediately. If the above work is carried out in a low pressure system, clamps are not used. To fix the flange, you will need a wide electrical tape.

Insertion into the water supply from metal pipes

the flange is made independently from a pipe, the inner diameter of which coincides with the diameter of the laid line. Compliance with this condition will provide the necessary tightness for the entire system;
you can use a tee with the desired diameter. To do this, a part of the pipeline without a branch pipe is removed from the part. Then the consumable is cut, a hole is made. To fix the pipeline, welding or a branch pipe is used;
experts advise welding the flange to the pipeline. Welding work is carried out around the entire perimeter of the product. The welding technique can be replaced with a sealant and a clamp.

Using a special device, holes are made in consumables under pressure. The principle of the method under consideration:

removal of insulation;
pipe surface cleaning.
installation of a flange on the supply pipeline with its subsequent fixation with a clamp;
connecting the valve to the flange;
installation of a drilling device;
cutter insertion through the valve;
hole cutting;
removal of drilling equipment;
blocking the water supply from the pipe.

According to the above technology, it is possible to make a tie-in without welding into a steel pipe. This technique is somewhat different from the technology of tapping into a polypropylene product without using welding. Therefore, before starting installation work, it is recommended to determine the type of consumable used. Its calculation is made with a margin. Upon completion of the work, the system is checked for leaks. In case of violation, additional repair work is carried out. They can be done independently or with the help of specialists. If the system is sealed, the line is ready for operation.

The most affordable way to provide a house with water supply is to tie into an existing water supply, that is, into an existing central highway. However, not in all cases it is possible to shut off the water, which makes it necessary to tap into the water supply system under pressure.

Features of tapping into a water pipe

Before starting any work, it is imperative to obtain the appropriate permission for this. When performing an illegal installation process, there is a high probability of being held administratively liable.

According to the rules, for the tie-in, you should take a permit signed by the management of the local water utility and a plan of the site where the work will be carried out. In addition, technical conditions will be required, for which you will have to visit the central department of the water utility. Specifications usually contain information about the connection point, data for the tie-in, as well as the diameter of the pipeline of the underlying pipeline.

In addition to the workers of the water utility, other companies specializing in such work with the appropriate license can develop design estimates. The price for services related to the preparation of documentation for tapping into a pressure water supply system may be slightly lower for such organizations.

However, in the future there is a possibility the emergence of a conflict with representatives of the vodokanal, who do not always approve such design developments.

Once you have received the necessary paperwork, contact the SEC where to register the project. Here you will also need to write an application to obtain the necessary permission to connect to the water supply system.

In accordance with generally accepted standards, only licensed professionals. The person who ordered the implementation of this service can only save money on digging and filling the trench with his own hands, as well as on auxiliary work that does not require permits.

There are some situations in which inserting a pipe into a water supply system is prohibited:

connection to the highway without installing a meter;
lack of connection to a centralized sewerage system;
a larger diameter branch branch than that of the main pipeline.

Manhole construction

To simplify the tie-in process, you can build a manhole about seventy centimeters wide.

Such a well will be enough to place shut-off valves in it and perform the necessary manipulations for connecting to the water supply. Such a structure will make it easier in the future to carry out possible repairs to the home system.

To make a well dig a pit the required parameters, the bottom of which is covered with a ten-centimeter layer of gravel. To form a reliable foundation, the resulting “pillow” is covered with a sheet of roofing material. A concrete screed is poured on top.

After at least three weeks over the hardened slab the walls of the mine are laid out. For this purpose, brick, reinforced concrete rings or cement blocks can be used. The mouth of the pit is raised flush with the surface.

When building a well in a site with frequently rising groundwater, make it waterproof. It is most convenient in this regard to use a ready-made plastic container, which is attached to a concrete base. The upper part is covered with a plate with a hole for installing a hatch.

Water pipes are made of several types of materials: plastic, cast iron or steel. It is worth paying attention to each of them.

Connection with plastic plumbing

When working with a plastic pipe, after determining the location of the tie-in, the site is prepared. To this end, the surface of the future puncture is carefully treated to get rid of the paint.

To the cleaned area with bolts fasten the clamp-saddle with terminals to be able to connect the welding machine. If an electric-welded collapsible clamp is installed on a plastic pipe, the vertical and direct-flow pipes are initially disconnected.

At the point of connection to the main a hole is being drilled using special equipment. The drill is inserted exclusively at this point to further block the water flow with a shut-off valve.

To ensure the tightness of the joint, an overlay is used during the drilling process. If the insert is made by a welding machine, the hole is made when the surface has completely cooled.

A new pipe is attached to the flange located on the valve. A clamp is mounted over the junction, which soldered by welding machine to the highway. A tap can be screwed to the hole of the clamp.

This manipulation is not necessary, but it improves the functionality of the new pipeline branch. In the future, if it becomes necessary to stop the flow of water, it will be enough just to turn off the tap.

Working with cast iron pipes

When connecting a solid cast-iron pipe to a water supply system, a certain sequence is observed:

Working with cast iron pipes requires the use of several crowns for drilling. They should have built-in carbide cutting inserts. It is important to prevent possible overheating of the equipment, which can be avoided by wetting the cutting parts with water.

Cast iron is a fairly brittle material, so drilling must be done at low rpm and low pressure for equipment. When the power tool is pulled out of the hole, it may be hit by a jet of water. Therefore, a protective rubber screen should be installed between it and the cartridge.

If it becomes necessary to use a saddle clamp, for a snug fit to the pipeline, it is necessary use rubber seal. It can also be equipped with a special machine, consisting of a blocking bolt, a flushing cock, a ratchet handle and a shaft with a drill. The design is framed by a metal housing with a guide sleeve, necessary to facilitate the drilling process.

Steel pipe installation

Pipes made of steel are characterized by their rigidity with simultaneous plasticity. Their installation can be carried out in a manner similar to the insertion of polymer analogues. When working with them, you must follow a certain sequence of actions:

The upper layers of the highway drilled with a perforator, and the remaining few millimeters are worked out manually.

Required materials when connecting to the central pipeline

Depending on the material of the water pipe, it may be necessary to use certain additional pieces of equipment.

To crash into a plastic pipe with a pressure of about 1.6 MPa, it is necessary to use saddle ring clamp. This device has a spiral with a cutter used in the formation of holes. When buying a saddle for tapping into the water supply, you should pay attention to the barcode marked on its body. It ensures the accuracy of the parameters of the created hole.

For tapping into a cast-iron or steel pipe, you need to buy saddle clamp. This fixture is divided into two parts, which are pulled together by bolts during operation. The metal seat is equipped with a locking plate.

to the pipeline bracket mounted. A tie-in into a steel water supply system can also be carried out without the use of a saddle by welding a branch pipe, however, with this method, the diameter of the main pipe, which must be with a large cross section, matters.

Today, thanks to an affordable price and excellent quality, specialists have gained great popularity saddles with integrated valves and cutter. They are usually used when tapping into a pipeline under a pressure of not more than sixteen bar.

They are equipped with a coupling, which allows installation by a welding machine. The most attractive feature of these saddles is their good resistance to corrosion processes, extending the service life up to fifty years.

The final stage of the tie-in

The final step in any pipeline connection process is the testing of the connected system components.

For this purpose, in the created new branch pressurized water supply, and from the other end of the pipe, the accumulated air is bled using a tap located on it.

After checking all the elements of the water supply for tightness, you can dig a trench, laid from the backbone to the point of connection with the home network.

The technology of tapping into the pipeline depends on the type of pipeline material. And since municipal water pipes are assembled from galvanized, cast iron or polymer pipes, for completeness of information we will have to consider not one, but three tie-in technologies at once. So, let's begin.

If polymer fittings were used in the construction of the communal highway, then the tie-in into the water supply under pressure will be implemented as follows:

The drill is inserted into the pipe only through the shut-off valve, which is closed after the “breakthrough” of the pipe body and the removal of the cutting tool. In this case, drilling is carried out using a special nozzle that ensures the tightness of the joint. And in some models of electric-welded saddles, a cutter crown is built into the bends, which is rotated with an external collar or adjustable wrench.

In the final, it remains only to bring the pipe of the external branch of the water supply into the trench, connecting it to the shut-off valve using a compression coupling.

Well, if you wish, you can build a viewing well at the installation site. To do this, you need to deepen the bottom of the pit, forming a sand and gravel cushion on it, on which the mine rings are lowered (the first one with walls cut under the pipe). If desired, the pillow can be strengthened with a 10-centimeter pour of M150 or M200 grade concrete. The head of the well with a hatch should go to the zero level of the soil. This design will facilitate the repair of home plumbing. After all, the owner will have the opportunity to block the system not only with the help of a central valve located in the house.

Tapping into a cast-iron water pipe is carried out a little differently. After all, a metal pipe is much harder than a polymer pipe, but the plasticity of this material leaves much to be desired - cast iron can burst at any moment. Therefore, when arranging the tie-in, the following technique is used:

To drill a hole in a cast iron pipe, a special crown with carbide cutting plates is used. Cast iron cannot be cut with other tools.

Finally, the crown is removed from the valve and the water flow is blocked. Installation of the external branch of the domestic water supply, extending from the saddle to the meter, is carried out according to standard rules.

The arrangement of a manhole over the tie-in is desirable, but not necessary.

In terms of ring stiffness, steel pipes are not inferior to cast iron fittings. But steel is a more ductile iron-carbon alloy than cast iron. Therefore, when tapping into a steel pipe, you can use original technologies that are similar to the methods of joining polymer pipes. As a result, the technique for arranging a tie-in into a steel pipeline is as follows:

The pipe is dug up, cleaned of rust and prepared for welding.
Next, a threaded or flanged branch pipe made of “main” fittings is welded (butt) onto the pipe body. However, for the branch pipe, you can choose any kind of tubular steel from structural steel.

After welding, the seam is checked for leaks by smearing it with kerosene from the inside and outlining it with chalk from the outside. Oil stains on the outer surface will indicate defects in the tightness of the joint.

In addition, it should be noted that the slope of the outer branch and, accordingly, the branch pipe of the saddle should be 2 degrees towards the house. And after assembling the external branch, before installing the water meter, it must be checked for leaks. Burying a trench from the tie-in to the house is possible only after a successful check of the tightness of the pipeline.

Insertion into household plumbing inside the house

With the help of a tie-in, we can equip a branch from the main home water supply line, with which you can connect an additional source of consumption or an irrigation system.

If the water supply is powered from a well, then a tie-in into the pipe can be arranged anywhere. With main water supply, the tie-in can only be installed behind the water consumption meter.

At the same time, the technology for arranging the “internal” tie-in is somewhat different from the method described above. After all, the pressure in the internal network can be turned off at any time by simply blocking the central shut-off valve. Therefore, for the tie-in in this case, you need a regular tee, and the work itself is implemented in the following way:

Installation of a new line is carried out with a running water supply. After all, the outlet of the tee is blocked by a separate shut-off valve.

Summing up

As you can see: pipe insertion is not very difficult. True, the technique of welding installation of a pipe to a steel water supply system is available only to professionals. But the installation of saddles on a polymer or cast-iron pipeline will not cause difficulties even for an unprepared home master.

As a result, you can embed home water supply into the main line even with your own hands. Just do not forget to get permission from utilities and other regulatory organizations. Otherwise, your tie-in will be cut off as an illegal connection, and all your efforts will be in vain.
