In response to Re: American Standard toilet makes random "pressure release" sound.
: Dear Terry and message board,

: My wife and I have a slightly less than 2-year-old home with new American Standard toilets with the 3142 valves. The toilets work great, and as far as I can tell do NOT leak. However, at random times they'll make a sound as though "releasing pressure."

: It's not a flushing sound, nor is it the same sound that happens when one forces the ball down to cause the valve to allow water into the tank. It's more of a very fast (and fairly loud "PFFFFFFFFFT" sound!)

: Is this "normal" for the American Standard toilet? Is it a sign of problems to come? We know this is happening on at least two new toilets...

The fill valve is most likely going bad. I had the same problem on my A/S Hamilton. I replaced the fill valve with a Fluidmaster 400 replacement valve & it works fine. A/S is still the best toilet maker in the business. Sometimes though, the stock fill valves they use are cheap.
