Another type of pipe is made of copper. They are mostly used for transmitting both cold and hot water. As well as, they are also applied for refrigerant lines in the HVAC system. They are liberal. You can use them for above-ground or underground water system.

A qualifies copper can live up to 50 years or so. However, by the course of time, they can thin out that can cause them pinhole leaks. Now, several plastic pipes occupied the position of copper as it requires high labor and effort to cut and install. Consequently, some builders find relief in the alternative, especially in PEX.
Polyvinyl chloride is known as PVC in short. The PVC is used in different types of plumbing projects from drainage to main lines. Along with that, irrigation piping, home, pool, spa or building mission, PVC is a good choice for many builders.
They mainly come in white but other color options also available. The color and mark on the pipe will tell you what the pipe is for. For instance, the pipe with the black letter on the purple pipe is born to reclaim water.
