Working of the Kohler Toilet
There is a lever on the side of the toilet and when you pull it. It pulls on the chain which in turn lifts the flapper valve allowing water to flush off. After the water leaves the tank, the chain releases, the flapper goes back to its position, and the tank refills.
Detecting the Problem
There is a test that you have to take to detect the problem that is causing the toilet leakage. For that follow the steps:
- First of all, flush the toilet so that all the water leave the tank
- Then refill the toilet and mark the water level in the tank
- Now turn off the water supply
- Leave the toilet unused for almost 6 hours
- Now check the results
Case 1: If the water level is not changed, it means that the fill valve needs to be replaced
Case 2: If the water level changes but it are at the level of the flapper, it means that the flapper is damaged and needs to be changed
