Why Is My Toilet Constantly Running?

July 7, 2021 | Blog

Is your toilet running? Better go catch it! It’s not an uncommon problem if your toilet doesn’t stop running after the normal flush cycle, but you may not know why your toilet is running or how to fix it. Parker & Sons Plumbing is here to help you figure out what to do if your toilet won’t stop running. Sometimes, people will wait and hope the toilet will stop or they will try and jiggle the handle in hopes something will happen. Unfortunately, neither of those is going to solve the situation. It’s important to address the problem as soon as you can because otherwise it can waste a lot of water and can cause your bill to go up.

So, What Is the Problem?

You can inspect your toilet yourself. But it’s never a bad idea to hire a professional to make sure there aren’t any other issues. Furthermore, you might need some tools and materials to be able to fully inspect your toilet and diagnose the problem. Some things you may need are rubber gloves, cutting pliers, toilet replacement parts, a replacement fill valve and a multi-bit screwdriver.

Check the Float

One of the common reasons for toilets to continue to run is water overflowing into the tank bowl from the overflow tube. If there is too much water in the tank, this can happen.

If this is the case, you’ll want to lower the float. To do this, you’ll need to loosen or tighten the screw until the float arm lowers. This will lower the water levels in the toilet.

Another way is to lower the water in the toilet with a column float attached to the fill valve. Then loosen the screw or clip, push down the float, and then tighten everything up again.

Check the Flapper

A typical toilet has a flapper that seals the water in the tank. A very common reason for toilets to continue running is that the flapper is old and needs to be replaced. Flappers that are too old, start to not seal away the water as well anymore. That can result in water constantly passing from the tank into the bowl, which causes it to continue running.

When you flush the toilet, the lift arm in the tank raises and pulls on a chain that is attached to the flapper. When it raises, it allows water to go into the toilet bowl. After enough water has been released into the bowl, the flapper re-seals the tank.

If the flapper is the cause of your running toilet, you can remove that old flapper and replace it with a new one that you can get at the hardware store.

Before you switch the flappers, it’s recommended to drain the water from the tank. You can do this by shutting off the water supply to the toilet and then flush the toilet to drain the water. To remove the old flapper, detach the chain and take the flapper off the pins from the side of the overflow tub. Then, connect the chain and attach the pins of the new flapper.

Shorten the Refill Tube

Another potential cause of your running toilet could be that the refill tube is continuing to pump water into the bowl. This can happen if the refill tube is too long or isn’t positioned properly in the overflow tube. If this is the case, you’ll need to shorten the refill tube.

To shorten the refill tube, pull the tube out of the overflow and hold it above the opening of the overflow tube. From there, trim it off and clip it to the side of the overflow tube to keep it from shifting.

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Shakira C.

Excellent Service! We had some work done on our kitchen and Parker and Sons were able to come out to our house and help us with our remodel. Great guys and great service. I would recommend them to anyone needing a plumber service.

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
