fluidmaster toilet valves again
I've been unable to solve the low pitched "thunk" noise (vibrating pipes)
that happens when the Fluidmaster 400a shuts off the water after a flush. I tried reducing the flow at the shutoff valve, but then I got a worse type of problem of an oscillating bang caused when the toilet shutoff valve closed beyond a certain point. I tried shutting off the water altogether and draining the pipes but that didn't help. It seems a cost effective solution would be for me to replace the darn Fluidmaster valve with a Korky Quietfill valve (which does not cause hammer). Only thing is I hate to having to waste the time replacing the valve just because of, what, in my opinion, was a bad design choice (if it's really true that the pipes are being harmed by the abrupt shutoff of the Fluidmaster.) According to the Fluidmaster website, they make a "whisper" model that supposedly mitigates water hammer (albeit with a slower fill). I'm wondering if a good quick fix could be done by swapping the top part of a "whisper" model??? Or, is there is any other inexpensive modification I could make to the Fluidmaster that would accomplish the same thing (WITHOUT having to drain the tank and remove whole)??? (and, no, I don't think it makes any sense have a "hammer arrestor" installed is much more expensive than simply replacing the toilet valve) Thanks, J. |

Its not the fault of the Fluidmaster. Its not their job to prevent water hammer, that would be the job of the plumber that installed your pipes. Perhaps there are some valves that can do 2 jobs and you like those. But IMHO its a problem with the house piping. Install whatever works and enjoy your time doing something else. Unless you are a plumber. IN which case you might enjoy installing a hammer arrestor and seeing the more perfect functioning of your system. -- Thank you, CL Gilbert "Then said I, Wisdom [is] better than strength: nevertheless the poor man's wisdom [is] despised, and his words are not heard."

I do agree with you, but those Fluidmasters do tend to shut off very abruptly. Ideally he should install arrestors, but any ballcock that shuts off gradually is the easiest fix. I should say, I am surprised his washing machine does not cause water hammer too. They also shut off abruptly. Mark |
