toilet pipe rattle after flush
Comments
-
A rattle -- not a water hammer -- is usually a pipe slightly loose in a hanger somewhere. Flush valves can cause an almighty water hammer in some cases, and that's best taken care of by a water hammer arrestor being fitted to the pipe. But a rattle? On a plain vanilla toiler? I'd look for a loose hanger.Br. Jamie, osb

The Watts PRV is a logical assumption. I would check it with hose bibb pressure gauge to see what the house pressure is and see it there is in fact a pressure fluctuation when the toilet is flushed. A pressure fluctuation may be because of a faulty sticking PRV or tank fill valve. The fact that you have a PRV indicate that the street pressure is higher than desired. 55 to 65 psi is an optimal pressure for a residence.
If this is a problem with only one toilet I would probably suspect the toilet tank fill valve.0 -
Thanks Homer! Sounds logical0
