Wonder why your toilet won’t stop running? That constant leaking, humming sound coming from your toilet isn’t just annoying — it’s expensive.

Toilet leaks waste up to 200 gallons of water per day. The average Fort Worth home water bill is $40-60 per month — an unfixed toilet leak can double that cost (or more). 

Tarrant County homeowners are already facing rising water bills. Don’t add to them by leaving a running toilet unfixed — we used our service data and expert plumbing knowledge to compile a list of why your toilet won’t stop running, and what you can do to fix it.

Here’s what to do if your toilet won’t stop running:

• We identified the 5 most common causes of running toilets. Your fill valve, flapper and float are the most likely culprits, but it may also be your flapper chain or toilet handle. Good news: many of these problems have DIY solutions!
• Is it a cracked pipe or fill valve? Look out for a cracked overflow pipe or broken fill valve. These are common issues with older units and wobbly toilets.
• Call a local plumber for help. Don’t attempt to DIY fix a cracked overflow pipe or broken fill valve. We’re here to help.

Our Plumbers Explain Why Your Toilet Won’t Stop Running

We asked three of our master plumbers why toilets run continuously. The reason your toilet won’t stop running lies in your tank. Shut off the water valve behind your toilet, take the lid off, and you’ll likely find the culprit with a simple visual scan.

Most continually running toilets have an issue with one of 3 parts:

1. Flapper: The rubber or plastic disc that seals the opening between your toilet tank and toilet bowl. Most flapper issues related to running toilets stem from worn out flappers with poor seals.
2. Float: The device attached to your toilet fill valve that moves up and down to open and close the valve. Most float issues that relate to running toilets are due to the float level being set too high.
3. Chain: The chain that connects your toilet handle to the flapper. Most chain issues that relate to running toilets stem from the chain being too short or long.

The top 5 reasons your toilet won’t stop running

We analyzed our recent Tarrant County service calls for toilet repairs — specifically ones related to water flow issues. These are the 5 most common reasons why your toilet won’t stop running:

1. Toilet handle is stuck. First, check if your toilet handle is too tight or a bad fit. Loosen the handle slightly and check to see if the problem is fixed.
2. Flapper is worn out. Worn down flapper seals allow excess water to leak from your tank into your toilet bowl. 
3. Float height is too high. The float signals when your water tank has filled to a sufficient level. Make sure the float height is set below the overflow tube to avoid this issue.
4. Flapper chain is the wrong length. If your chain is too short, the flapper won’t close completely. Too long, and it may pinch between the flapper and flush valve — this causes water to leak into your bowl. Aim for ½” of slack on your flapper chain.
5. Fill tube is disconnected. Make sure the fill tube is properly connected to the fill valve. If not, the bowl won’t fill properly after flushing.

Call us ASAP if you find these 3 problems

If you still can’t locate the reason your toilet’s constantly running, look for one of these 3 less common issues. If you find one of them, schedule a service appointment with us quickly — you could waste up to 200 gallons of water per day.

1. Refill tube length. If your refill tube is too long, water will flow from your tank to the overflow valve — this causes a continuous filling cycle.
2. Cracked overflow pipe. A common problem with older or wobbly toilets. A cracked overflow pipe results in continuous water leakage from your toilet tank to your bowl.
3. Faulty or broken fill valve. Check for leaks around your toilet fill valve — you may hear a humming noise, or the sound of constantly running water. A broken fill valve may also cause your toilet to take forever to refill. 

We don’t suggest trying to repair a cracked overflow pipe, broken fill valve, or any toilet leak you can’t identify. We’ll find and fix the problem, and give you a great warranty on parts and labor.
