I recently installed a Toto UltraMax toilet. The toilet works fine. However, the fill valve starts to leak after a week or so. It will shut the water off at the appropriate level. Then a slow leak will occur and the water level will slowly rise until it leaks into the overflow tube after 10 to 15 minutes. I have replaced the fill valve twice, but all three fill valves have this problem. The problem does not begin until the fill valve has been in the toilet for more than a week. I have tried to adjust the height level ever so slightly, but this does not stop the leak.
What is the problem?
How do I fix it?
Thanks.
