Leaky one piece toilet
#1
We have a circa 1957 American Standard one piece toilet which is leaking from tank to bowl (model 327-2005) Have replaced the flapper valve/ flush valve with new brass 0 ring one and put bead of silicon between tank and brass and brass and gasket (per plumbing supply store advice). Also replaced fill valve with Fluid Master 400A- still a slow leak. Please help-
