Most if not all faucets and shower valves can be repaired. It is just the plumber that does not want to do that type of work as they can get a whole lot more doing the rip out and replace method.

There are a few parts in a faucet that most people do not know about. One is the seat. This little part inside the faucet assembly is often forgot about and is the easiest part to replace. And more often then not when its not replaced even with new washers installed will case the faucet to continue to leak when turned off.
