CPVC and PVC pipes are often confused for the same thing sold under two names. They're not. CPVC is built to carry hot and cold water supply reliably: bathroom and kitchen lines. PVC is generally for drainage and cold, lower-pressure use. Mixing them up is a common, expensive mistake.
The real test is years of hot water. CPVC holds its shape and joint integrity under sustained heat; PVC used on a hot line will soften and eventually fail, usually inside a wall, where a burst joint means broken tiles and a contractor bill that dwarfs whatever was saved on pipe cost.
If a contractor suggests substituting PVC on a hot-water run to trim the budget, ask directly what it's rated for. Our team can spec the right pipe for every line before the walls close up. It's a five-minute conversation that avoids a very unpleasant one later.
