After a toilet is flushed, water will refill within the tank and then stop once it reaches a certain level. However, when parts of the toilet are broken or malfunctioning, water will continue to run (annoying, we know). If you find that one of your toilets is running with no plans of stopping, there are things you should be checking that will usually solve this plumbing problem.

toilet repair and replacement

Adjust the Water Level

The tank’s water level is decided by the height of the adjustable float piece. When the float is at too low of a height, the flush will be weak and might not flush all of the waste. However, when the float is set too high, water will constantly pour into the overflow tube and the fill valve won’t shut itself off. Adjust the height of the float accordingly to make sure the water level in the overflow tube is at the water level mark. This water level mark is equivalent to an inch below the critical level mark on the fill valve.

Fix the Flapper Chain

Attached to the flapper is a chain that needs to be a specific length in order for it to open and close during a flush. A flapper chain that’s too long will prevent the flapper from fully opening, shortening the flush. On the other hand, a flapper chain that’s too short will prevent the flapper from fully closing, allowing water to continuously leak into the bowl. Inspect your current chain and make sure it’s in good condition and that it has a small amount of slack when closed. If it doesn’t, adjust the chain accordingly or replace it altogether.

Inspect the Flapper

Each piece inside of the toilet tank should be inspected when the water continuously runs, especially the flapper. When the flapper is worn out or cracked, the result will be the same as if the flapper chain was too short. If there’s any damage associated with the flapper, head to the hardware store and pick up a replacement. You should turn off the water leading to the toilet and bring the flapper to the store to get as close of a match as you can. Once you install the new flapper, make sure it creates a complete seal by giving it a test flush.
