At PEX fittings compression PEX tubing held a special split ferrule, which is compressed when unscrewed, the external threaded portion of PEX fitting long nut. Tighten nut ferrule tightly clasps metal pipe, pressing her inner surface to the surface of the PEX fitting socket. Seal joints provided sealing rings located at both the socket PEX fitting, and inside the clamp nut. The connection of metal pipes with compression PEX fittings – loosely, permits repeated assembly – disassemble of joints.

Each of the PEX fittings described has its advantages and disadvantages. Press PEX fittings are securely connected to the metal-tube, because the connection pipe PEX fitting, achieved an almost one-piece molding. However, mounting press PEX fittings require special tools to crimp – press machines, manual or hydraulic. Work on installing the press PEX fitting requires some experience, bad crimp crimp sleeve can cause an accident PEX plumbing. Installation of compression PEX fittings is carried out by conventional wrenches, movable or carob, a connection can make the installer even with little experience with metal-PEX tubing. However, the connection obtained in this way is often leaky, which leads to leaks in the joints of compression PEX fittings and metal pipes.

Pipes, connections are done with the use of press PEX fittings, thanks to the reliability of the connection can be removed in the channels of the work being done in the walls, that is, possible to hide the installation of PEX plumbing. Connection made by compression PEX fittings require constant monitoring for leaks, so the main area of their application – water pipes, mounted an open way.

The main requirements for PEX fittings: To ensure a reliable connection between a pipe and PEX plumbing fixtures, long-term trouble-free operation, and ease of installation, ultimately decreasing the cost of works on arrangement of PEX plumbing.

Pumps, corrosion-resistant stainless steel manufactured by Grundfos for the past thirty years, they have proven themselves in practice, working in municipal, industrial and individual PEX plumbing systems around the world.

Installed in a borehole or well, Grundfos pump is very quiet. As the power used by alternating current from the normal power supply with a voltage of 110 V and 50 Hz. All wetted parts are made of water proof materials, which provide long service life, without compromising the quality of water.

3-inch submersible pumps SQ comes in five versions with different capacities to ensure the supply of 1 to 7 m3 / h and pressure up to 200 m.

Of the 33 standard sizes of pumps can be for any artesian well to choose the most suitable, which, thanks to the optimum hydraulics and a new electric motor will consume much less electricity than most others.

Thanks to the use of modern bearings, Grundfos UP15-10SU7P Comfort System pumps SQ can pump water with a certain concentration of sand. Their motors have built-in protection against running dry, overheating, overvoltage and voltage drop, pumps SQ can used from independent sources of power.

Now widely adopted pipes modern environmentally friendly materials – PEX.
What are the advantages of these Plumbing PEX pipes?
They are simple, quick and clean to install, resistant to acids and alkalis, does not corrode, they can be “zamonolichivat” into the wall, have an absolute tightness of joints, low cost, and for heat resistance superior to any other PEX tubing.

However, pipes made of PEX yield on frost resistance of PEX tubing. Already at a temperature of -5 to -15 * C PEX becomes brittle, so for outdoor water use them can not. PEX pipe and PEX fittings used in residential and industrial buildings for domestic hot and cold water, as well as the device underfloor heating. Because of its smooth inner surface, they have high permeability. PEX fittings are manufactured from special chrome-plated brass pipe PEX fittings from PEX, so they can be easily connected with stainless steel PEX plumbing.
Operating temperature pipe to +95 * C.
Operating pressure for the cold PEX plumbing pipes 1,0 MPa, and the hot – 2,0 MPa.
Life with preservation of the original qualities of 25 years for pipes and PEX fittings and hot water 50 years – for the cold.
Thus, choosing PEX tubing, you get a cost-effective, hygienic, reliable and durable water system.

PEX fittings – elements of PEX plumbing systems that provide direct or angular connection of separate parts of metal-water and allow the transition between pipes of different diameters. Structurally PEX fittings for metal pipes is a PEX fitting inserted in the pipe and connects with the threaded part of the valves, filters, meters and other PEX plumbing fixtures. The most common types of PEX fittings used in the installation of metal tubes – press PEX fittings, PEX fittings, and compression.

PEX fittings press PEX fittings are mounted in the lumen of metal-press test tube by a metal sleeve, stainless steel, put on the pipe at the junction of pipes and PEX fittings. Tightness of such a connection is provided by O-rings to be placed in concentric grooves on the socket PEX fitting. Press test crimp sleeve press PEX fitting, single operation, if necessary to disassemble the connection, it simply cut off with part of the metal-tube, then put in its place a new press PEX fitting.
