How to Fix a Running Toilet

 

A running toilet could mean dozens of gallons of water wasted every day it keeps running. You might have tried pulling on the lever and jiggling it around, but sometimes the toilet just will not seem stop. You might have even removed the top cover to find a bunch of tubes that do not look damaged, and so the mystery begins. Before you grab your phone and call a plumber, try following these simple guidelines that will help you find the cause of the problem and fix the issue in no time.

Check the Flapper

The most common source of problems when it comes to toilets that constantly run is the flapper. It is a round rubber cap that is connected to the flush lever, which opens and closes to let the water into the bowl when you flush the toilet. To check if the issue is in the flapper, grab a stick and push down on it at the bottom of the tank. If you notice the water stops running, you are dealing with a flapper that is not sealing correctly.

If this is the case, you should first shut off the water supply valve under the toilet, flush it out, and unhook the old flapper. If it has build-up on the edges that is preventing it from closing properly, try cleaning it out. If it is warped, cracked, or broken you will need to replace the flapper. Purchase a new flapper from your local hardware store, install it according to the instructions on the package, and hook the flapper chain back onto the flush lever arm.

Check the Fill Tube

If pressing down on the flapper did not seem to stop the water from running, your problem might be in the fill tube. The fill tube is the small plastic tube that connects the fill valve to the overflow pipe designed to drain water if the tanks fills up too much. The fill tube should not be underwater, if it is, but it back so that it can level the water.

Check the Float

If the fill tube does not seem to be the issue either, you will want to check the positioning of the float. The float ball shuts off the fill valve when the water reaches its critical level mark. If the float ball is set too high, it might be letting the tank to fill up too much. Simply bend its arm downwards to set a lower water limit.

Check the Fill Valve

If you were not able to find any issues with the previous components, the problem might lie in the fill valve. It might have cracks that are letting the water leak through and will need to be replaced. To do this, first shut off the water supply and drain the tank. Then, proceed to unscrewing the lock nut outside the tank that connects the water line with the fill valve, and remove it. Take the old valve with you to your local hardware store to make sure you purchase the right kind and size. Install and secure the new valve, and finish by adjusting the float to the critical water level mark.
