Before we start with the discussion of  tubing installation, we need to know what PEX plumbing is all about. PEX is a type of material used to make plumbing pipes for various advantages and features that it provides. This is the material which has no match even when compared to copper and iron pipes. This is one of the most purchased products in the plumbing product market. When you buy the PEX plumbing materials, there are many advantages that you will gain for the safety of your house.

The first and the foremost advantage that you will get is that of easy PEX plumbing installation. The main reason for this easy installation is that the tubes can be tweaked and turned to a certain extent without the use of fittings. However, this is not possible with the copper, iron or plastic tubes. For these tubes one has to make use of fittings round the corners when the pipes have to take a turn. The installation of fittings requires professional help as doing it clumsily may lead to leakages. Therefore with very few fitting and in some cases none, it is very easy to do the PEX plumbing installation all by yourself.

When you do the PEX installation on your own, you save a lot of money. Firstly the labor cost that is spent on the professional service is removed. You can rather use this money in getting higher quality tubes and installing them yourself.

Another way to get  plumbing installation at a cheap price is to get it done by a dealer. The purchase of the PEX plumbing and the installation can be given to a single dealer. This will get you better discounts and prices.

Typically, plumbing with PEX assures that absolutely nothing should go wrong plus the pipeline will not likely outflow. PEX plumbing systems targets sustainability. PEX tubing system meets all sanitary constraints everywhere.

PEX tubing plumbing is not difficult and calls for no heat up or any solvent. plumbing tubes tools flexes simply around corners, does not necessitate lots of accessories, consequently lessening installation period
Tubing tools provides the exact same exterior diameter as the copper pipes, which enables it to be taken for equally hot in addition to cold water. Even so, tube carries a better heat resistance than most water lines and are generally utilized in home heating systems.

Plumbing pipe can cost a smaller amount if you opt for a sizable volume of that these porn files. Some find the following as being a huge advantage, especially when they have it to replace the complete house plant. Nevertheless pipes offers use a negative aspect.

Much more material is indeed low-priced, small number producers are going to change costs for small quantities marketed to buyers. For top level selling prices PEX tubing tools must locate a while. It’s strongly recommended especially if you do not have to buy large quantities. An additional way to get a small selling price to purchase is to buy large volumes directly coming from the producer, which might supply you with a discounted of up to 20% in the original amount.

Right now, a lot more buildings are beginning to work with tubes plumbing. If you use PEX products for your pipes it is not going to get a fire inside your house or maybe your building, considering that the material is fire resistant. Another important matter concerning PEX is its substantial resistance and resilience. The plumbing crimp tools could even be employed for chemical throw away water and the conduit is not going to damage. PEX is portrayed by a widespread issue – an excellent price / top quality percentage.

PEX Plumbing system network after experiencing internal pressure is mounting on the strength and integrity. experience plumbing pipeline hydraulic or pneumatic way twice. To eliminate leaks in mint or other compounds and the identification of fistula in the pipes for the first time the pipeline have to backfill the trench and install the valves.

The second time the pipeline passes the final test after backfilling of trenches and completion of all work on this section of the pipeline. Preliminary testing of PEX Plumbing system networks need to start after the joints become necessary strength.

This test is performed after filling the pipeline with water (for hydraulic test) or air (pneumatic test). The test pipeline is separate parts of a length not more than 1 km.

Scheme of hydraulic test plumbing pipeline:
1 – subject truboprvod;
2 – support;
3 – flange;
4 – air release valve;
5 – temporary inflow;
6 – hydraulic press;
7 – manometer;
8 – control valve;
9 – cork valve;
10 – gauge tank

When testing with water that there was no displacement of pipes, the ends of the pipe is closed with blank flanges and fixed stops. Then fill the pipeline with water from the temporary PEX Plumbing system, watching the removal of air from the pipe through the crane mounted at the highest point of the pipeline.

With the help of Taco pump plumbing pipeline creates the necessary pressure. As such a pump Firm Agrovodkom “proposes to use hand pumps GN-200 GN-500 GN-60. When testing a plumbing pipeline should consider the possibility of pipe rupture and dispersal of the fragments, so you need to take all measures to prevent.

Dead-end circuit network consists of trunk and branches, which leave in the form of dead-end sections. In a dead-end water network is moving in one direction – until the end of branches. Dome scheme – the shortest in length, but less robust with respect to a continuous supply of water.

During the accident at a railway station all the sites that are behind them, will not be provided with PEX plumbing supply.

Ring circuit has no dead-end sections, and all its branches are interconnected and closed.

Combined scheme consists of a dead-end loop-back and lines.

Ring and a combined scheme of water supply more reliable in operation. In the loop-back network of water is not stagnant, but constantly circulating. Emergency shut down sites without interrupting the water supply to other consumers.

Track PEX Plumbing system networks align with the vertical and horizontal layout of the area and taking into account other underground utilities. PEX Plumbing system network of travel, as a rule, put a straight line and parallel line development, severely on the highway.

Intersection plumbing pipeline to perform at a right angle to each other and to the axis passing through. Accommodation PEX Plumbing system of lines in relation to other underground utilities should allow installation of networks and to avoid washing away the foundation in case of damage PEX Plumbing systema.

Distance in terms of PEX Plumbing system of parallel networks to buildings and structures must be determined depending on the design of building foundations, depth of burial, the diameter and characteristics of networks, water pressure in them, etc.

Normal operation PEX Plumbing system network is impossible without a reliable fixture.
PEX Plumbing system network sets of different fittings:
shut-off and adjustment (valves and pressure regulators), and water-safety (extinguisher, vantuzy, etc.). Function valves – this overlap of fluid flow or start-up, switching the direction of flow and change its flow, pressure, speed.

Unacceptable to the reverse movement of water in water line to the pumps Taco 007 IFC apply the brass ball valve.

Valve – mounted on the outer pipe PEX Plumbing system networks to stop the flow of water or disable individual sections of the network. Changing cross-sectional area hole valves, regulate water flow in the pipe.

disc valve, which is used most often.

Spindle during the turning does not go out and raise or lower the wheels, which open or close the tube. Wedges placed between the disks during rotation of the spindle is pressed disks jacks.

Latches produce a diameter D – 50 to 1000 mm and height H – from 280 to 2325 mm.

PEX Plumbing system can be put into operation, if during the hydraulic test it will not be revealed ruptures of pipes, fittings or butt joints, and if the actual water leakage will not exceed the allowable. The final test of PEX Plumbing system often combine with the delivery of plumbing pipeline into operation.

Before the commissioning of the pipeline can be disinfected, for which he filled at night with water, the composition of which contains 20-30 mg / L chlorine. Then the pipeline was washed, and only after a satisfactory bacteriological analysis allowed to use water for drinking and household needs.

Duration of last irrigation should be equal to the time required for the tenfold change of the volume of water in the plumbing pipeline. During the trial operation, which may last several days, carefully check the work of the entire valve installed on the plumbing pipeline.

Polymeric materials, which are called in everyday plastics, have become part of everyday life man, penetrating into all areas of industrial production. The use of PEX plastic pipe began almost simultaneously in Europe, USA and Japan in the early 50′s of XX century.
These pipes due to a number of positive properties actively began to replace steel and cast iron.

Polymer pipe lighter metals and asbestos, do not corrode and easily connect to the system. By the year 2000 in Western Europe polymer pipes to dominate:
in Switzerland, the extent of their use in new construction and major repair was 70%, Finland – 51%, Germany – 46%

And despite the fact that somehow not quite serious look coiled into rolls colored plastic tubes on a background of heavy (sturdy) steel and iron pipes, scales the global construction market has steadily declined in their direction. Polymeric pipes have a number of advantages, that will surely gain the upper hand over their shortcomings.

Connection PEX Plumbing system of cast iron pipes:

1 – cast iron pipes;
2 – asbestos cement;
3 – tarred rope

Strand of hemp, which is used for striking tube sockets, must be insulate and cleared of contaminants. Before the introduction of a slip-joint gap meerschaum strand twisted into a bundle of such diameter that it was a tight slit bell. If the resin is used for striking a rope, it untwist the individual strands are then twisted into a bundle the required thickness. When insulate separate bundles per layer is necessary that the ends of the bundles do not overlap, and placed and do not create local swelling. Entered into a slip-joint seal gap harnesses powerful blows of a hammer on insulate. Sufficiency seal each layer of the wiring harness in the flare gap is determined by the typical metal insulate bounce when you hit it with a hammer. The remaining annular space in the bell mint asbestos-cement or lead alloy is poured sulfur. To connect the pipe bends and branches PEX Plumbing system networks use special cast iron fittings – elbows, tees, crosses, adapters, etc. For joint use Portland cement 300-400, sifted.

Asbestos cement joints have higher technical quality compared with cement joints. They are flexible and allow for deflection of 1 degree until leakage at the junction and are more resistant against the corrosive action of aggressive water and soil. The greatest strength and flexibility have lead joints. They can withstand the pressure of 15-30 kg/cm2, but due to their high costs apply only to the most critical areas of PEX Plumbing system network. Increase the flexibility of a butt weld cast iron pipes can be applied to the rubber ring instead of the hempen strand.

At the organization of water supply at home inevitably raises the question of choosing the material of communication. If you chose to metal pipes, then you might be interested in this article.

PEX Plumbing system network consists of pipes, fittings, valves and wells. Outdoor PEX Plumbing system network paves the metal (steel, cast iron), asbestos or plastic pipes. For economic and operational performance material for water pipes is adjusted depending on the purpose of PEX Plumbing systema, working pressure, the diameter of plumbing pipeline and the nature of soils.

Cast-iron water-pressure pipes with cast iron fittings paved diameter of 50 mm and above. Cast-iron pipe can be normal, designed for operating pressure up to 10 kg/cm2, and reinforced with a pressure of 16 kg/cm2. Cast-iron pipes in the manufacture of hot asphalt-covered with lacquer, which makes their surface smooth and protects against corrosion.

The connection of cast iron pipes is accomplished by squeezing and stamping their joints asbestos-cement, sulfur or lead alloys. Spigot joint consists of a watertight seal of asbestos and tarred rope and a lock which holds the sealing material into the socket

For the formation of the joint even the end of one tube is inserted into the socket the other so that between the end of a smooth finish and bell bottom formed a gap of 3-6 mm, which is designed for axial movement of pipe under thermal expansion. This gap seal ring made of rubber or zakonopachivayut, twice encircling the pipe resin is well twisted rope (hemp strand). Thus the seal between 1 / 2 to 2 / 3 the length of the bell.

Common Problems in PEX Plumbing

Although the creation of PEX materials did eliminate many of the problems that are associated with metal piping materials, there are still a few problems that commonly affect PEX plumbing systems. These problems are relatively mild in comparison to the cracking, breaking and soldering that metal piping material has become known for. PEX is known for being much easier to install than other types of systems because it is flexible and less connections are required in the average plumbing system.

One major problem that is associated with the use of PEX pipe is that it is not able to be used outdoors. PEX is only meant to be used underground and indoors as a water delivery system. PEX is resistant to freezing temperature and will expand as ice forms in the pipe and will contract as the ice int he pipe melts. However, the pipe will not resist a hard freeze when it is placed out doors. This is one of the reasons why California requires that even pipes that are placed underground have a sleeve throughout the entire distance that it is underground. Most states only require that a sleeve is placed where the pipe enters the building.

Another common problem that is associated with PEX plumbing is damage from rodents. It is a common problem, particularly with piping that has been placed underground outdoors. Rodents will attempt to chew through the pipe. Sometimes they are able to completely break through the pipe with their teeth, and other times they are only able to cause a leak. Either way, this spells bad news for inexperienced plumbers and can be quite hard to find and deal with.

Another common problem that is often associated with PEX piping material is the presence of biofilm, caused by bacteria int he pipes. This can cause a number of different issues within the system and is most commonly found in non-chlorinated systems or in systems that do not see much use throughout the year. Often times this problem is seen in cabins and vacation homes. Systems that fall into these categories should be sterilized every so often to ensure that this does not occur.

People at all times sought to improve his life: to make her comfortable, modern. Therefore, the appliance manufacturers, seeking to satisfy customer needs, improve their products, expand the functions, maximize reliability, followed by a modern style. But there is an area on which we begin to think in an emergency. If the appliances are always “is in sight”, such devices as Taco 007-SF5 pumps inconspicuous, and we are reminded of their existence only when problems occur. The owners of villas and private homes otherwise suited to solving this issue. They know better the scope of Taco 007 SF5 pumps, but are not inclined to innovate and buy proven model. And they both could make their lives more comfortable, if we turn our attention to the advanced pumping equipment for household use.

In multi-story buildings located in older areas traditionally not pressure PEX plumbing  pipe, which leads to inconveniences and problems of modern household appliances. But these problems can be solved by installing a circulating pump pressure boosting production directly into the plumbing pipeline. Thanks to the work of such a pump in the tubes and normalized to increase the pressure in the pipes. Pumps have a robust design: a housing mounted rotating element (rotor) with a fixed propeller.

The water passes inside the body, lubricating bearings and cooling pump. In the absence of water built-in sensors automatically shut off modern pumps it, or include in its admission. If you want to move the toilet to build a bath in another room, or make a washing machine on the balcony, you can use modern automatic settings with macerator Clean WG. Their device like a conventional flushing toilet, made from high quality plastic, including the pumping unit, which silently and efficiently pumps plumbing to a distance of 100 meters. As there is a chopping mechanism that allows the use of small diameter pipe.

This is to avoid the formation of the suction PEX plumbing pipe air bags. Directly on the discharge pipe pump is a check valve. His appointment, automatically disconnect the Taco 008 pump from the reservoir pressure if the engine stops (or crashes). Between the check valve and pressure valve manifold is located (or gate) 8 throttle to control the Taco 009 pump and disconnect the plug from the pressurized network. With a diameter of plumbing pipeline of more than 300 mm valves are often performed with an Taco or hydraulic drive. The collector is located on pedestals.

Shown at the location of PEX plumbing pipe pressure above the level floor is convenient for installation, as well as oversight of the pipeline, but the cluttered aisles for staff. With this arrangement in places of transition through PEX plumbing pipeline suit catwalk. To release the premises have a PEX plumbing pipeline pressure in the ducts below the floor and overlap the past corrugated steel.

Before starting the Circulating and axial flow pumps supplied by them should be filled with fluid. If the level of fluid intake is above the top of the pump or the intake manifold is pressurized, the fill Taco pump such as Taco 006, Taco 009, Taco 0013 produced by opening the valve on the suction tube and letting the air through the tap is located at the top of the pump housing.
