I can't get my flush valve to work properly. I replaced the filler with a new fluid master, and replaced the whole #4 valve assembly. I have a one-piece from 1936 that has the three bolt holes from the original valve. I replaced those plugs (cleaned the holes first with wadded paper towels) and put the new assembly in. Now, every 6 or seven minutes enough water leaves the tank somehow to prompt a small "flush"/refill. I have snugged the new brass ring down pretty tightly, and I've even squirted food coloring in the tank to try to trace the leak with no luck. The rubber flapper seams pliable, all new parts are fully secured and everything was dry when I installed it. Anyone have any ideas that I can try? I forgot to mention that I think I have the water level set correctly (above the tilt valve) Thanks in advance!

What about the small refill tube? What did you do with that?

I put it back down the overflow channel in the corner where the old one was. No water drips out of it once the intial fill is done.

Knock on wood, I think I've got it figured out now; I put the old flush valve cover back on (the rubber disk) and I haven't had a leak in about half an hour after flushing. I think the one that came with the new assembly didn't sit right (which is weird since it comes as a set). One thing I did notice is that even when the new one was totally screwed in there was some play with the brass screw... The shaft was able to move up and down a little, so maybe there wasn't enough constant downward pressure (but that's how it was designed). With the old disk installed again the fit is snug, and maybe that's the solution... And maybe the new one should be fitted with a washer to snug it up? I guess I'll cross that bridge when the old one wears out.

And maybe you should raise the small refill tube OUT OF THE OVERFLOW channel. It should terminate above the opening.
