Water Supply best material choice?
A water supply line is only as good as the material that was used on the application of water supply line, depending on the size of pipe will determine the options available. Most residential homes in a non freeze zone will be made of CPVC, or copper water pipe, Pex pipe is the main supply line used in Freeze States for it's expansion if water get's below 32 degrees. All of these pipe's do not build up scale, rust and reduce pressure over time, CPVC has a problem of becoming brittle and breaking when a repair or replacement is made with this material, copper is expensive and does not flex or expanded when the water becomes frozen. Pex pipe by an approved manufacturer is the best choice based on price, durability and flexibility when making turns or water becoming frozen in the colder climate areas.
