Handyman Tips – San Jose – When your toilet runs
When your toilet runs, what happens is water continuously flows from the inlet to down the bowl.
There are two valves in every toilet.
The fill valve is where the water comes in to fill the tank.
The flush valve is what the water goes through to move from the tank to the bowl to active the flush.
So the first question is which valve is failing?
Troubleshoot fill valve
When you remove the lid of the tank, you will see (generally to the left of the tank) the fill valve and it’s float.
Fill valves work with a buoyancy mechanism.
The water level raises the float, the float is attached an arm that is attached to the the valve.
There are two possibilities:
- Float is improperly adjusted and it’s hitting something that stops it before the valve is fully closed.
- The valve is broken and doesn’t fully close no matter what.
Troubleshoot flush valve
The flush valve is generally in the middle of the tank at the bottom and consists of two parts; the valve seat (which is attached to the bottom of the tank) and the flapper valve which lifts when you use the handle to flush.
To test if the flush valve is leaking, pour food coloring into the tank until there is no mistaking that the water is colored.
If the water in the bowl becomes colored, the flush valve is not sealing completely.
If the water in the bowl does not become colored, the flush valve is sealing and your problem is the fill valve.
