Since PEX was invented the world of plumbing installation has become a lot easier. However there are a few things that one must never do when installing PEX water tubing systems for heat, water of gas. The PEX water tubing material may have a large warranty period, but this only occurs if the material is in proper conditions and with the right tools. Whenever making any PEX tubing plumbing it is vital that the PEX tubing system is reachable. Do not place the PEX tubing plumbing way under the tub or sink, instead try installing the PEX water tubing closer to the edge so that it can be reached and replaced when needed. Any PEX tubing install needs to have proper fixtures; this will prevent water from infiltrating through the fixture on to the pipe and on to the floor.
PEX tubing needs to be handled with care and it is strongly advisable that the one installing the pipes to try and leave the pipes as long as possible and fold the PEX tubing pipes instead of adding more and more fixtures that could leak.
One of the biggest mistakes people do when it comes to using PEX pipes is that they mount these tubes inside walls. Some may not leave enough space for the pipe and isolate it inside the wall. Pressure inside the pipe and pressure from the wall on to the pipe can cause for the tube to crack and water can infiltrate on the surfaces. This not only damages the whole wall which will need to be taken down in order to fix the pipe, but it will also damage the whole installation which will need replacing. Because PEX tubing come in a variety of colors, on can chose a color to match the walls so that the pipes can be installed outside the surface and not inside the wall area.
Another important aspect when using these types of installations is trying to pay a little more for a better quality. PEX that has a reinforcing aluminum foil inside can be a bit more expensive, but it will certainly worth the money invested. These type of pipes last up to three times more than regular PEX tubing, so savings on replacing the installs are quite possible even if one pays a bit more to start with. As in all products, long term investment in quality items brings on long term savings.
