Knot the junction consists of a tee valve (valve) and nozzle. This site is well placed in a standard concrete diameter 1.0 m. The inset in the main, padded asbestos-cement pipe, tee embed, establish a special saddle. Water-measuring unit is designed to track the number of water consumption. Equip them, if possible, in dry areas with ambient temperatures not lower than 2 C. Most often, water-measuring units installed in the basement. A simple water measurement site has a shut-off valve, drain valve and water-measuring device.

Valves and valves make it possible to remove the water meter for repair or disable the internal networks of water supply. Water meter is used for metering water into the house, on the branches, which give water to large consumers. There are several designs of water meters, among which in the systems of internal PEX plumbing system are the most common high-speed water meters.

The principle of operation is based on their proportionality between velocity and flow of water. With a small flow of water (up to 10 l / h) is most often used with impeller water meters with a caliber 15, 20, 30 and 40 mm. , Whichever is available as a counter mechanism (in the Hydro-insulated chamber or in the aquatic environment), water meters are Super dry and mokrohodnye. Meters vane need only be installed horizontally. Error of the meter shall not exceed ± 5%.

For internal PEX Plumbing system networks use steel, stainless steel, brass or polymeric pipes. Water-gas pipes with small diameters, intended for internal networks, there are black and galvanized. Pipes with zinc coating are more durable, it would be preferable, especially for potable PEX plumbing system.

The ends of the tubes may be smooth, intended for welding, or have a cylindrical or conical thread. Conventional internal PEX plumbing, with operating pressure up to 6 kg / cm 2, for ease of repair is mounted detachable.

To connect the water-gas pipes used connectors and fittings (fittings) with an internal cylindrical thread, which are made of ductile iron, steel or brass. Sealing of threaded joints perform flax on the paint or special sealing tape. If the operating pressure in the network exceeds 6 kg / cm 2, the connections should be carried conical thread.

Laying plumbing pipeline systems of hot and cold water using metal-dimensional tubes regulated Code of Practice SP 40-103-98, developed the RF State Committee for Construction and Housing Complex. When designing the internal PEX Plumbing system recommended pipe riser more than 20 mm. Floor join the risers should be carried out, usually from pipes OD 14 and 16 mm through the distribution headers.

Making the best out of your PEX piping will demand the use of some insulating materials. This is especially the case since some of the homes we have tend to have very low temperatures during the winter season. Insulation for the PEX pipes are usually the same for other pipes and these should not present such major issues in purchasing them. In fact, some of the various materials used in insulation can be found in your local improvement center. They come in different forms of diameter, so as to match up with the PEX pipe diameters. They are relatively inexpensive to buy, install and maintain. The installation steps below do not require any prior plumbing professionalism so as to understand. It is a simple procedure that will be done in quite a short while. Probably some of the things that will be needed are the insulation, insulating tape and utility knife or scissors.

1) The first step is to slide the insulating formed pipe over the PEX pipe. These foam insulation come in lengths of six feet each. In case one wants to add the insulation over greater length, one just needs to butt together these insulation, using the scissors to cut to size the material in order to tightly fit the pipe. One also has to make sure that the fittings are fitting together from end to end.

2) After ensuring that the insulation fittings have been put in place, removing the plastic adhesives that are on the edges of the foam insulation at the same time needs to be done. This will expose the adhesion on them. One here has to be careful that the insulation lengths are adhered in the right way in order to perform at optimum capacity.

3) These have to be available; tape the lengths together, one after the other in order to ensure that the insulated material has properly been sealed. It is necessary to make sure that the seal is air tight. This is a precautionary measure to avoid heat loss of any kind.

The process, as seen is an easy one. The one thing that one has to be careful though in doing is taking care of those places that need to have some form of joints. A lot of heat is lost at the joints and one will need to put this into consideration. Put more care here for better results.

The developing individual building brought to life using new materials and technologies. Of course, in a modern house is assumed that an adequate level of comfort is largely determined by properly organized hot and cold water and an automated heating system.

In Chicago, for domestic pipeline systems of cold and hot water and heating up recently, mainly used steel pipes and flexible podvodok only to devices used in PEX and copper alloys. But long experience has shown that the steel pipe corrosion, their life is low – 10-15 years, corrosion products degrade water quality and clog the inner cavity of pipes, reducing their bandwidth and degrade the performance of fixtures and devices, automatic control system. In this context, requires the search for alternative solutions to ensure the work of pipelines without corrosion damage, although the accumulated decades of tradition impede the application of new solutions and requires a major effort to teach designers, builders and operators of the application of novel materials and technologies.

PEX tubing Canada production of polyvinyl chloride, PEX of high and low density, PEX used in PEX plumbing and sanitation and for the technological pipeline. In the 90 years from abroad have entered the market PEX tubing. Currently, the material is being distributed primarily from Germany (AQUATHERM), Italy (AQUATECHNIK), Czech Republic (EKOPLASTIK), Turkey, as well as from Italy (COPRAX). Behind them there are other types of PEX tubing of different companies. This PEX tubing systems: CRONATHERM, REHAU, UNIPIPE – Germany, WIRSBO – Sweden, HENCO – Belgium, GIACOMINI – Italy, KISAN – Poland, METZERPLAS – Israel polibutenovaya system UNJVERSA and some others. In 1996-1997. Ministry of Construction of Chicago were adopted revisions to SniP 2.04.01-85 “Inland water main and sewer building and 2.04.05-91″ Heating, ventilation and air conditioning, which opened to wide application in domestic systems of cold and hot water and space heating pipes made of polymer materials. The purpose of this article is to analyze the applicability of these materials on the example of industrialized countries in Europe.

Over the past decade in these countries, there is increasing use of PEX tubing systems for domestic hot and cold water and heating, and in some industrialized countries on these pipes is about 60% of pipes used annually for new construction and repair.

At the present time to build and repair of external engineering networks are increasingly used PEX tubing. However, the scope of the polypropylene tubes are much wider, because of their unique properties. Suffice it to say that it is possible to transport various chemical solutions. It is no exaggeration to say that the PEX tubing with Oxygen Barrier for the economy become as necessary as cold stores in the summer. In those cases when you need a special strength and durability of tubing, used their reinforcement by special trains, most commonly used aluminum and fiberglass. Reinforced pipes on operational parameters may well replace expensive cooper pipes for plumbing, known for their reliability. One of the technologies of reinforcement lies in the fact that the pipe is covered with a layer of aluminum foil on top of a layer of PEX (PEX-AL-PEX). Thus we obtain three-layer construction – two layers of PEX and between them a layer of aluminum. PEX Pipe manufactured by this technology, different lower coefficient of thermal expansion and can be successfully used for the construction of thermal paths.

There are several varieties of PEX:

* Polyethylene, crosslinked by the peroxide method – PEX. He has a very high degree of cross-linking – 85% and shape memory effect;
* Polyethylene, crosslinked by silane method – PEX has a very low degree of cross-linking – 65%. Cross-linking is not uniform across the thickness of the material. PE-Hb tighter compared with PEX A, which makes installation and application domain. Shape memory effect is less pronounced, which makes the pipe less resistant to mechanical influences;
* For a physically PEX with tools, obtained by irradiation with hard X-rays and low degree of cross-linking – 70%. This is a hard material, which limits its field of application. Shape memory effect is less pronounced, which makes the pipe less resistant to mechanical stress.

PEX tubing, PEX characterized by the following properties:

* Corrosion resistance. Lack of surface corrosion and cracking in tension;
* No deposits. Material of  PEX pipes does not contribute to the formation on the surface of solid deposits, ie does not cause overgrowth of tubing  salts and scum;
* Poor conductivity of sound. The velocity of sound is much less compared with metal pipes;
* Shape memory. This effect is extremely important when connecting pipes, when laminated tube through a small period of time begins to recover its original shape, it covers tightly fitting before the protrusion sliding sleeve, thereby increasing the strength of the connection. In addition, bent at an angle pipe can return to its original state after a while if it is not pre-fix;
* Low thermal conductivity. Helps keep the coolant during transportation;
* Pipe diameter 32 mm bend without the use of special tools;
* Resistance to high temperatures and pressures;
* High resistance to abrasion;
* Very high impact strength even at low temperatures;
* Toxicology and physiological safety;
* Low roughness 0,007 mm;
* Lightweight;
* Quick and easy permanent connection by cold pressing;
* The service life of more than 50 years.

If you are confused about the term PEX, it refers to polyethylene made with cross linking techniques. The result of this technique produces a high strength polyethylene, which is so long lasting that several PEX plumbing tubing (non-barrier) have been known to last as much as 20 decades!

High Strength and Flexibility
The modern PEX plumbing supplies have a reputation of being very high in both strength as well as flexibility. The high temperature range within, which these supplies can function, is another reason why they are so popular. The average temperature range within, which these PEX plumbing supplies can function range from below freezing point to as much as 200 degree Fahrenheit. This is why an increasing number of people have started relying on these supplies for hot and cold water plumbing systems, refrigeration warehouses and many other uses. In certain instances, these very same PEX plumbing supplies have been used successfully in radiant hydronic heating devices as well as snow melting devices, ice rinks and many more.

Easy Plumbing of Potable Water
With the help of modern PEX plumbing supplies it has become easier as far as plumbing of potable water is concerned. Since such pipes can easily withstand high as well as low temperatures in plumbing as well as heating applications, they are very versatile for usage. Considering the high level of chemicals present in typical plumbing environments, these PEX plumbing supplies are also resistant to these chemicals, thereby making them useful in such applications as well.
