How to Stop a Toilet From Running

A toilet that is constantly running can be extremely annoying. Learning to stop a toilet from running could give you peace of mind, which should help lower your water bills.

This toilet issue can have a few different causes. With minor problem, it may be something you can do about it on your own. For more serious issues, you will need to call a plumber Hamilton for help.

Let’s learn how to stop a toilet from running:

1. Open your toilet tank

If your toilet is always running, there is probably something wrong inside its tank. To find the cause of your problem, you first have to remove the tank’s lid.

Lift it, then put it down somewhere where it won’t risk falling and breaking. You don’t want to have to replace a cracked or chipped lid after you manage to solve your running toilet problem.

2. Adjust the height of the float

The float of your toilet tank is the part that controls the level of water in the tank. There are different models of adjustable floats, but you need to know that if your toilet’s float is set too high, the water will spill down the overflow tube. This means the fill valve will not shut itself off, and your toilet will keep running.

Look inside the tank. There should be a mark indicating where the water should stop filling it. If you can’t find any mark, note that the water should ideally stop around 1 inch down the top of the overflow tube.

If there is more water than that in your tank, you will need to adjust the height of the float, either by turning a screw, sliding a clip down a rod, or bending the lift arm of the float ball.

After adjusting the height of the float, flush your toilet to see if the tank now fills at the right level.

3. Check if the float has a bent lift arm

If the metallic lift arm of your float ball is too bent, it might cause some flush issues by forcing the float to sink into the water.

All you have to do is straighten the lift arm to restore its normal shape. Then, flush the toilet to see if it refills to a proper level.

4. Check your toilet’s fill tube

The fill tube of your toilet tank is a small flexible tube that goes from the fill valve to the overflow tube. Its purpose is to refill the toilet bowl after each flush.

If this tube is disconnected from the fill valve, or if the water that squirts out of it doesn’t fall right inside the overflow tube, your toilet will have a weak flush and could keep running after being flushed.

To fix this problem, ensure the tube is attached to the valve and adjust it so it will send water inside the overflow tube and down your toilet bowl.

5. Adjust the flush rod or the flapper chain

The flush rod and the flapper chain lift the flapper when you flush the toilet. If the flapper chain is too short, or if there are knots, the flapper cannot close, which explains why your toilet keeps running: it keeps trying to replace the water leaking down the bowl.

To fix this problem, adjust the chain on the rod so it will be long enough to allow the flapper to close. Don’t let it be too long, though.

If the chain is too long, or if the flush rod hits the toilet lid when you flush, you will not be able to flush properly.

6. Replace the flapper if it’s worn-out

Perhaps the water is leaking down the bowl because the flapper is worn-out. To replace it, you will have to remove the damaged one to take it to the hardware store, so you can buy a new one of the same type.

Start by turning off the water, then remove the old flapper and its chain. Buy a new one, snap it back, and attach the new chain to the flush rod.

Finally, flush your toilet to ensure the new flapper creates a good seal and stops the toilet from running endlessly.

7. Call a plumber if your toilet is still running

If there was nothing wrong with your toilet’s float, fill tube, chain, or flapper, the problem could be caused by a worn toilet tank gasket.

This gasket keeps a seal between the tank and the bowl of your toilet. If it’s damaged, the water will leak down the bowl, and the toilet will keep running.

If you need to replace a toilet tank gasket, it’s best to call a professional plumber who will be able to do it for you in about half an hour.
