Fluidmaster 400

Is there an adjustment on these so they don't shut off quite so fast, can't find the paper that came with it?

It shuts off with a 'boom' and the pipes shake. I'm on city water and the pressure doesn't seem excessive.

Thanks,

Baldwin

If it is not a pressure problem I don't see anything pertaining to your problem in my instruction manual. (just bought an American Standard toilet and they come with the Fluidmaster valve). I am including their website that has more solutions to problems. Good luck.

Never thought of looking there. Here's what it says:

Prof. Flush:
If you have a sudden banging of your water pipes or toilet valve when it shuts off, you have what we call "Water Hammer. If you are not using a Fluidmaster fill valve then this is a perfect oppurtunity to purchase at Home Depot the Whisper Fill Valve by Fluidmaster. This fill valve has a specially designed regulator that will reduce the noise as well as stop the "BANG" of your pipes.


I'll have to find me one of these.

Thanks

The Fluidmaster 400 is not particulary prone to hammer; it does taper the flow somewhat before shut off. It is quite possible that you have a high pressure problem, which no valve can overcome.

If you have water hammer you need a slow closing ball ****. Those are the ones with the arm and float ball. I like Wolverine Brass. You will pay more but it's worth it.

OK, I went and watched the float. It rises slowly with the water level about half way, stops for maybe 3 seconds then snaps to the closed position. Is this normal or maybe something is binding inside the valve for a couple seconds?

I installed this about a year ago and I sure the banging wasn't there then. We do have a lot of white chunks in our water.

I'm gonna check the pressure, out of curiosity, then buy a new valve and see what happens.

Thanks guys,

Baldwin

Whoa, white chunks in the water (esp the hot)?

Google the following:
"water heater" AND diptube
