Running toilet

Is your toilet running?  It's probably the fill valve.  See the photo.  The float on the fill valve moves up and dow,n controlling the water filling the tank.  At times, a worn fill valve's float will cease to rise to the point of "shutting off" the water.  The result is a toilet that constantly fills or "runs".  Fill valves can be tricky to replace, so you may want to call a plumber.

Plumbing tip January 2015: Stop that running toilet

Plumbing Tip: January 2015, Stop that running toilet

1. Identify the float ball and float arm inside the tank.  This is the mechanism that shuts off the water.  Once it floats to the correct level it will activate the shut-off.

2. With tank lid off, and while the toilet is filling after a flush, observe to make sure the float is reaching the proper height.  If not, the toilet will continue to run, as the water will fall down the overflow tube.

3. If your float is not reaching the correct height, simply bend the float arm down. Do this near the middle of the arm.  This will allow the float arm to travel a bit further, and reach the shut-off point.

4. Flush the toilet and observe to see if the bend did the job.
