How to fix a running toilet

If your toilet is running and you have to jiggle the hanle to get it to stop, Greg will show you how to fix this quickly and easily. In many cases this requires no parts and no tools!

The most common problem is that the chain connecting the flush handle and the flapper valve is not adjusted properly and gets caught under the flapper valve, preventing a good seal. The water continually leaks out of the tank, and therefore the tank continually attempts to fill. Watch the video to see the proper amount of slack chain (about 2 links).

Another issue is a some part of the flush mechanism catching on another part. This is not uncommon, especially when a ball float is used. The ball float may catch on the flush handle arm, or even the flapper itself. In the photo to the right, the flapper valve is being held open by the float ball. A slight bend in the ball arm, or turn of the adjustment screw is all it takes to make it operate smoothly again.

If neither issue is the case, the flapper valve itself may be worn out. This is also an easy repair, but you must be sure to purchase the correct replacement part. See How to replace and buy a toilet flapper for detailed instructions on how purchase and install a new flapper valve.
