We recently moved into a house with 2 pressure assist toilets (American Standard). I've never seen these before, so I'm a little confused about how they work and how to fix them...
The first problem was that the flush on both toilets was really half-hearted. The flappers would shut after only about 1/3 of the tank had drained. To solve this, I adjusted the floats above the flappers (moving them from mid-way along the chain to right down on top of the flappers), and shortened the chains. This seemed to do the trick, and the flushes were a lot better since the flappers stayed open longer.
Now, I've noticed that the toilets hiss continuously (and occasionally make trickling noises). It's a really quiet hiss, but it looks like a small amount of water is always running down the inside of the overflow tube. Did I make the flappers so buoyant that they're no making a firm seal anymore? Or is this another issue?
Thanks in advance for any thoughts!
