  1. For older toilets: Check to see if the problem is with the float ball. If the float ball is stuck in the up position, it could be causing the water to continuously run. Simply push down on the float ball until it is in the correct position.

  1. If the problem is with the flapper, try adjusting it. The flapper is what keeps the water from running out of the tank. If it is not positioned correctly, it could be letting water escape. Try moving it around until it forms a seal.

  1. There could also be a problem with the fill valve. This is what allows water into the tank. If it is not working properly, it could be causing the toilet to run constantly. Try cleaning it or replacing it if necessary.

  1. The water level in the tank could be too high. All fill valves have an adjustment level for the fill valve float. In the center of the tank, there is an overflow tube that should be approximately 1” above the water level. If there is water running into that tube, the water level is too high. If this is what you are seeing in your toilet tank, you will need to adjust the fill valve float. 

If your toilet is still running (away) after trying these repairs, give the pros at Instant Plumbing and Rooter a call!

Frequently Asked Questions

Q: How do I know if the float ball in my toilet is causing the running water issue?

A: If you have an older toilet with a float ball, check if it’s stuck in the up position. This can cause the water to continuously run. Gently push down on the float ball to see if it returns to the correct position and stops the water flow.

Q: What should I do if adjusting the flapper doesn’t stop my toilet from running?

A: If adjusting the flapper doesn’t work, it might be worn out or damaged. Inspect it for any signs of wear or cracks. If it looks damaged, it’s probably time to replace it. Replacing a flapper is a simple and inexpensive fix that you can usually do yourself.

Q: How can I tell if the fill valve is the problem, and how do I fix it?

A: If water continuously flows into the tank or the toilet fills up too slowly, your fill valve might be the issue. Try cleaning it first to remove any debris. If that doesn’t work, you might need to replace the fill valve, which is a bit more complex but still doable as a DIY project.

Q: What’s the correct water level in the toilet tank, and how do I adjust it?

A: The correct water level is usually about 1 inch below the top of the overflow tube in the center of the tank. If the water level is too high, adjust the fill valve float. This is typically done by turning a screw or sliding a clip along a rod.

Q: When should I call a professional plumber for a running toilet?

A: If you’ve tried these DIY fixes and your toilet is still running, it’s time to call in the pros. Persistent running water in a toilet can indicate a more complex issue that requires professional expertise. Don’t hesitate to call Instant Plumbing and Rooter for reliable and efficient service.
