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 (cross linked polyethylene) is one of the most adaptable and convenient to use systems. This system has many advantages over the other plumbing system that use metal pipes made up of iron , copper, lead etc.
PEX pipes can be used in areas with extremes of temperature. It can withstand extremely cod and hot water. With proper arrangements, you can use these pipes with copper and steel pipes also.
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.
PEX plumbing installations require fewer fittings than rigid piping. The flexible tubing can turn 90 degree corners without the need for elbow fittings. Most plumbing leaks and system failures occur at joints in fittings. Since PEX requires fewer fittings, it has less opportunity to leak and installs faster. Also, attaching PEX tube to fittings does not require soldering.
These pipes can easily expand or contract as they are very flexible. Hence the chances of bursting here are very minimal which can reduce many plumbing issues. Moreover, PEX tubing does not transfer heat as readily as copper, and so conserves energy.
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.
