The first step that any one can think off during any plumbing emergency is to shut off the main water supply. But by doing so, we are shutting off the whole system which can create many problems until it gets fixed. But now, you need not worry about this problem. PEX system have a shut off valve at each supply line which allow you to shut off the water supply for the pipe that is causing the problem. PEX systems can greatly reduce your troubles concerning home plumbing.

PEX or cross linked polyethylene is one of the most versatile, easy-to-use plumbing systems available. It is part of a water supply piping system that has several advantages over metal pipe (copper, iron, lead) or rigid plastic pipe (PVC, CPVC, ABS) systems.

You can use PEX pipes for both hot and cold water. These pipes can even be used in combination with other pipes like copper, steel, PVC etc.

PEX tubing is made from cross linked HDPE (high density polyethylene) polymer. The HDPE is melted and continuously extruded into tube. Cross linking causes the HDPE to become stronger and resistant to cold temperature cracking or brittleness on impact while retaining its flexibility.

The installation process for the PEX plumbing is easier and faster as it requires less fittings. PEX pipes and tubes are very flexible and can bend up to almost 90 degrees and hence eliminate the need of elbow fittings. This also reduces the chances of leaks as most of them occur at the joints.

Another advantage of using PEX pipes is that they are much more flexible than metal pipes or PVC pipes. This reduces the chances of any kinds of bursts. These pipes are also helpful in saving energy as they do not transfer heat like metal pipes.

The installation cost of this system is less as compared to other plumbing systems. One, because PEX is less expensive than those metal pipes and second, because installing fewer fittings reduces the chances for expensive callbacks.

Many people are now becoming aware about the PEX plumbing system. Switching to PEX plumbing can prevent many plumbing issues as it is a much stronger and secure material.
