Inspect the Fill Tube

Ways To Repair Your Toilet

Find the fill tube by removing the tank lid if you’re having trouble with the overflow tube in your toilet.

A short, flexible tube connects the fill valve and the toilet overflow tube. After each flush, this tube squirts water down the overflow pipe to replenish the bowl as the tank fills.

The bowl won’t fill, and your subsequent flush won’t generate a strong siphon if this tube is detached or the water stream doesn’t reach the overflow tube. Carefully reattach the fill tubing to the fill valve.

Ensure the fill tube directs water into the toilet overflow tube and sits about an inch above the overflow tube’s lip.

Make sure the water flows down the overflow tube when you flush the toilet. If you take this step as soon as possible, you will know how to stop a running toilet in seconds.

Get the Fill Height Just Right by Monitoring the Float

Monitoring the Float

Mark one inch down the overflow tube if you can’t find it. Next, observe if the water stops flowing after flushing the toilet.

If it doesn’t, and the water keeps running, you may adjust the float level in the toilet tank. If your toilet is older, you may need to bend the brass rod that connects to the float ball to make adjustments.

Modern toilets, on the other hand, often require you to crank a screw or slide a clip along a rod. Make sure to flush the toilet after every modification. Once you’ve reached the desired level, adjust the float until the water stops pouring.
