There’s nothing more annoying than the constant sound of a running toilet – and it’s not just irritating, it can also lead to higher water bills and wasted resources. At Hudson Plumbing, we understand that plumbing issues can sneak up on you, but a running toilet is one you can often fix yourself with a little guidance. Here’s what to do if your toilet won’t stop running.

Step 1: Remove the Tank Lid
Start by carefully removing the lid from the back of the toilet tank and setting it aside. Be gentle – it’s made of porcelain and can crack easily.
Step 2: Check the Flapper
The flapper is a rubber valve at the bottom of the tank. When you flush, it lifts to let water flow into the bowl, then closes to refill the tank. Over time, flappers can wear out or become misaligned. Check to see if it’s sealing properly. If it looks worn, warped, or doesn’t seal tightly, replacing it is usually a quick fix.
Step 3: Inspect the Chain
The flapper is connected to the flush handle with a chain. If the chain is too short, it may prevent the flapper from closing. If it’s too long, it might get caught under the flapper. Adjust the length so there’s just a bit of slack when the flapper is closed.
Step 4: Adjust the Float
The float controls the water level in the tank. If the water rises too high, it will continually drain into the overflow tube. For older ball-style floats, gently bend the arm downward. For newer column floats, adjust the slider up or down.
Step 5: Check the Fill Valve
If none of the above fixes work, the issue could be a faulty fill valve – the mechanism that refills the tank. Sediment or wear can cause it to malfunction. Replacing a fill valve is inexpensive and can be done with basic tools.
