Have five year old Mansfield toilet. The trip level needed excessive force
to flush. I traced it to a gummy, sticky flush valve seal. Went to HD and
bought flush valve seal which fits the Mansfield 210 water saver mechanism.
Installed and the flush is good but have serious water leakage from tank
into toilet. I have adjusted the seal dozens of time but with no success.
Does the seal need time to form?
I'm stumped and would appreciate some suggestions.
