I've had one of those fluid master toilet float switches for 4-5 years with no problems. But then it started to make a loud bang (water hammer) when it would shut off. I replaced it with the same type. After about a month, it did the same thing. I returned it for another and again, this one worked fine for about a month until the water hammer started again. I've since turned the toilet supply valve about halfway closed to limit the water flow and solve the problem. But any ideas as to why this is happening?
- We have good county water and normally do not get any buildup of deposits.
- It worked fine for years, and the other bath rooms are working fine too (single story home).
- No water hammer problems with showers, sinks, etc. - only this toilet and only recently.
Thanks
