I appreciate your advice. I am concerend about PB piping in my house but so far it has not leaked (knock on wood). I've been in this house since it was new (built in 1990). When it becomes time to deal with replumbing the house, if ever, I'll come back here for more advice. For now, I'm remodeling the master bath.
I want to repalce the the existing T valves with something better. 1/4 turn ball valves is what most recommend.
I assume an "angle stop" valve is different from a ball valve. I'll goggle that term and see what it is. The plumbing pros here were recommending 1/4 turn ball valves on another post. Is there such a thing as a 1/4 turn angle stop ball valve?
Thanks
