I have an American Standard Toilet that is that same age as my house, about 18 years old. When the toilet refills the tank after a flush, the noise of the water going in is unbearably loud and to make matters worse, very slow. It can take a full 90 seconds to refill at full supply. I mean the sound is very loud, you can hear it across the house even with the bathroom door shut. I have lived in the house about six years and the issue is about the same as when I moved in. This half bath toilet is near the hearth room off a kitchen and is used by guests….and the wife says “fix the embarrassing toilet!” before the holiday guests arrive.
I think I hear two different noise pitches, with one coming from near the supply line and the other in the tank via the water filling. I have replaced the supply line and the supply line valve shut-off thinking they were clogged or something. I have bleed the lines throughout the house thinking it might be air in the line. No help. I can change the pitch of one of the noises by turning and playing with the supply line cut-off valve to reduce the amount of water coming in slightly, but that only slows the refill down and barley results in a less audible sound.
Is this a bad toilet,
too small of supply line (3/8),
bad fill valve
or god forbid a bigger whole house plumbing issue?
The other four toilets in the house are slow to refill, but not nearly as loud. My wife can deal with slow, but not the noise. Help.
