We have placed four new flappers on the toilet.
Then replaced a new flush, flapper valve system.
The flapper continues to leak causing the toilet to run.
Then we replaced the new flapper with four different ones.
What is the next step?

Hi Csmar

You can try installing another flush valve. If that fails, then your next step would be to call in a PLUMBER.

This is a simple job with no "tricks" or hints to offer you. Sorry, but that's all I have here!

Good luck!

Sound like another refill tube problem.

Is the little tube from the fill valve to the overflow pipe attached to the top of the overflow pipe, or is it sticking down inside the overflow pipe?
