Fist of all ---- Great Web Site!
Upon flush, toilet causes bathroom pipes to knock. Two other vanities on same line are OK. Restricting
shutoff solves problem, but it takes over 4 minutes to
refill tank. Pipes are 40+ years old with bathroom
remodeled 10 years ago --- wondering if it is deposits restricting flow into toilet??? Same problem seen
in one of the vanities several years ago, but cured
when replaced faucette (unrelated repair). Tempted to replace feed valve to toilet to see what happens (if
deposit in valve, maybe cured). Any thoughts?
Thanks in advance...
