A running toilet can raise your water bill and it wastes hundreds of gallons of water per day. Start by inspecting the toilet flapper for any issues. Toilet flappers are typically the issue when it comes to a running toilet. If it's not the toilet flapper, adjust your toilet's water level. If neither are the cause of your running water, most likely the toilet fill valve needs replacing.
CHECKING THE TOILET FLAPPER
- Turn off the water to the toilet.
- Flush toilet again to drain all the water.
- Adjust the chain if you need to. If it's too short water it can allow water to keep draining. If it's too long, it can get stuck in the flapper also allowing water to continuously drain.
- Inspect the flapper for signs of age and/or mineral build up. If it's worn, replace the flapper. If it's dirty, soak it in a bowl of vinegar for half an hour then scrub it clean with a small brush.
CHECKING WATER LEVEL
- Check water level in tank. If the water level is too high, water will constantly drain into the overflow tube.
- With the tank full, look at the open tube in the middle of the tank that connects to the toilet bowl.
- Adjust the the float to lower the water level if you see water draining into the tube. Adjust the screw attached to the float arm by turning the screw counterclockwise a quarter of a turn to lower the float. Continue adjusting until the water level is just right.
REPLACE THE FILL VALVE
- Shut off water to the toilet and drain the tank.
- Remove the original fill valve with a wrench.
- Take the old fill valve to the hardware store and ask for a suitable newer replacement.
- Install the new fill valve and turn the water back on.
- Test the fill valve and check the water level making adjustments to the float until the level is just right.
