 toilet hissing
Author: gholman (WA)

Hi folks,

Hopefully a beginner question...

Toilet started hissing sound, and the water level in tank has dropped by 3/4". Thought it might be the flapper because when I pressed on the flapper the sound stopped. Replaced flapper. Nope, still hissing. Unless replacing the flapper didn't fix it.

The sound seems to come from the Toto Max Flushing System.

Any ideas what I should try next?

Thanks -

Gareth

The hissing is probably from the fill valve. Turn off the water supply and see if the hissing stops.

Chain too short and holding up flapper?

Yep it does. OK - going to research how to adjust/fix the fill valve now. Thanks!
