Fluidmaster Cistern Valve

Oct 12, 2008 3 Replies

Had a bit of an overflow and wondered if the washer in the Fluidmaster ball valve might need replacing. I have a pack of the diaphragm type washers for the conventional plastic ball valves - will these fit? Or are Fluidmaster washers / diaphragms unique?


I haven't had one fail, but they do warn that they're quite suspectable to any debris in the supply. There's a procedure when you install to remove the cap, invert a mug over top and turn the water on full, to ensure any debris is flushed out of the pipework before it's put into service. Might be worth repeating that.

Mmmmm - Wish I had a service valve!!!

Do I ask my wife to hold the mug - or work the stop tap?

Turn off the stop c*ck & fit a service valve?
