HELP! 2 questions on an old house plumbing (updated pvc)
Posted by tavis on June 18, 2003 at 08:34:44:
When I turn on the hot water side in my tub (farthest thing from my water heater) It starts knocking violently. If I only turn it on very low it will not do it. This morning I had problems where I had a screaching and very little hot water pressure at all until I let it run for a while. It started working as always (if you turn it up, it knocks). I take it as the problem is going to the next level. My sink in that bathroom does not have this issue (closer to the hot water heater).

2nd question is I put an AMerican Standard Smart valve 2000 on my toilet and it works fine till it shuts of, then it "slams". I take it it is shutting off too quickly. I have read her to REPLACE it. What is recommended as a replacement?
