The handle needs to be held down for 15 seconds to allow all the water to drain from the tank. Anyone know how to make sure the flap in the tank stay up while the water drains out. It doesn't float upright when initially flushed. In all other aspects the flap works fine.

Try to shorten the chain a link or two, that may help... Back to you... Milo

This could be as simple as adjusting the linkage. Make sure that there is a quarter inch of play in the linkage when the flapper is seated. Does it flush. Better now? Good luck, Tom
