How to Fix a Toilet That Won’t Refill

A toilet that won’t refill can be a major inconvenience, especially if you’re in a hurry. There are a few different reasons why this might happen, and the solution will vary depending on the cause. In this article, we’ll walk you through the steps to troubleshoot and fix a toilet that won’t refill. We’ll also provide some tips on how to prevent this problem from happening in the future.

So, what causes a toilet to not refill?

There are a few different things that could be causing your toilet to not refill. Here are some of the most common causes:

  • A clogged fill valve: The fill valve is responsible for regulating the flow of water into the toilet tank. If it becomes clogged, it can prevent the tank from refilling properly.
  • A faulty float: The float is a small, buoyant device that controls the level of water in the toilet tank. If the float is damaged or misaligned, it can prevent the tank from refilling properly.
  • A leak in the toilet tank: If there is a leak in the toilet tank, water will constantly be draining out, preventing the tank from refilling.
  • A problem with the water supply: If there is a problem with the water supply to your home, it can prevent the toilet from refilling.

How to troubleshoot a toilet that won’t refill

Once you’ve identified the possible cause of your toilet’s problem, you can begin troubleshooting. Here are the steps to follow:

1. Check the fill valve. The fill valve is located at the bottom of the toilet tank. It is a small, cylindrical device with a hose attached to it. To check the fill valve, turn off the water supply to the toilet and flush the toilet. If the water does not stop flowing into the tank, the fill valve is likely clogged. You can try to clear the clog by using a thin, pliable object, such as a wire hanger. If you are unable to clear the clog, you will need to replace the fill valve.
2. Check the float. The float is a small, buoyant device that controls the level of water in the toilet tank. It is located on the inside of the tank, near the top. To check the float, turn off the water supply to the toilet and flush the toilet. If the water level in the tank does not rise to the top of the overflow tube, the float is likely damaged or misaligned. You can try to adjust the float by gently bending the rod that it is attached to. If you are unable to adjust the float, you will need to replace it.
3. Check for leaks in the toilet tank. To check for leaks in the toilet tank, turn off the water supply to the toilet and flush the toilet. Look around the tank for any signs of water leaking. If you see any leaks, you will need to repair or replace the toilet tank.
4. Check the water supply. To check the water supply, turn on the water supply to the toilet and flush the toilet. If the toilet does not refill, there is likely a problem with the water supply to your home. You will need to contact your local water provider to resolve this issue.
