Trying to help a friend with a running A.S. toilet
Never seen a design like this before. Searched the heck out of google and goole images and can't find any visuals.
It's an American Standard toilet. No idea which model. Water fill doesn't shut off completely.
It may be 3 years old or so.
The valve assembly has a twist knob on top (may be yellow), with a black body underneath.
The "float" is a large plastic reservoir that manages to defy the laws of physics and sink even though there are no holes for the air to escape. I believe the plastic float thing has Fluidmaster stamped in it.
Cleaned and inspected the flap and it does not appear to be stiff or deformed (despite our very hard water in Chicago).
Anyways, found some info in my searching-- does this sound like the dreaded "smart valve?" Does continued running sound like the typical problem?
Is the "silent recall" still in place?
