‍A running toilet can be a frustrating and costly problem for homeowners. Not only does the constant sound of running water become an annoyance, but it can also lead to an increase in water bills. Fortunately, identifying and fixing a running toilet is a relatively straightforward process. With the help of Johns Plumbing and Drain Los Angeles, we’ll explore the causes of a running toilet and provide you with a step-by-step guide on how to fix it.

Signs of a Running Toilet

A running toilet is easy to identify if you know what to look for. One of the most common signs is the sound of running water, even when the toilet is not in use. Another sign is if you notice the water level in the toilet bowl is constantly fluctuating. You may also see water leaking out of the base of the toilet. If you suspect that your toilet is running, it’s important to address the issue as soon as possible to prevent wasting water and potentially damaging your plumbing system.

Causes of a Running Toilet

There are several reasons why your toilet may be running. One of the most common causes is a malfunctioning flapper. The flapper is the rubber seal that sits at the bottom of the tank and controls the flow of water into the bowl. If the flapper is not sealing properly, water will continue to flow into the bowl, causing the toilet to run. Another common cause of a running toilet is a faulty fill valve. The fill valve is responsible for refilling the tank after each flush. If the fill valve is not functioning correctly, it can cause the tank to overfill and lead to a running toilet. Other causes of a running toilet may include a damaged float, a clogged inlet valve, or a broken chain.

Tools Needed to Fix a Running Toilet

Before attempting to fix a running toilet, it’s important to have the right tools on hand. You’ll need a pair of pliers, an adjustable wrench, a screwdriver, and a replacement flapper or fill valve, depending on the cause of the problem. It’s also a good idea to have a bucket and a towel on hand to catch any water that may spill out of the tank.

Step-by-Step Guide to Fixing a Running Toilet

Now that you have the necessary tools, it’s time to fix your running toilet. Follow these steps to resolve the issue:

  1. Turn off the water supply: Locate the shut-off valve behind the toilet and turn it clockwise to shut off the water supply.
  2. Drain the tank: Flush the toilet and hold down the handle to allow the tank to drain completely.
  3. Remove the tank lid: Carefully lift the lid off the tank and set it aside.
  4. Inspect the flapper: Check the flapper for any signs of wear or damage. If the flapper is worn or damaged, it will need to be replaced.
  5. Replace the flapper: If the flapper needs to be replaced, turn off the water supply to the toilet and flush the toilet to drain the tank. Remove the old flapper and replace it with a new one. Be sure to follow the manufacturer’s instructions for installation.
  6. Check the fill valve: If the flapper is not the problem, check the fill valve. Turn the water supply back on and let the tank fill. If the water level in the tank rises above the overflow tube, the fill valve may need to be adjusted or replaced.
  7. Adjust or replace the fill valve: To adjust the fill valve, turn the adjustment screw clockwise to decrease the water level or counterclockwise to increase the water level. If the fill valve needs to be replaced, turn off the water supply and follow the manufacturer’s instructions for installation.
  8. Test the toilet: Once the flapper or fill valve has been replaced, turn the water supply back on and let the tank refill. Flush the toilet to make sure that it is no longer running.

Tips for Preventing a Running Toilet

Preventing a running toilet is as simple as following a few simple tips. First, avoid flushing anything other than toilet paper down the toilet. Flushing items such as feminine hygiene products, wipes, or paper towels can cause clogs and damage the plumbing system. It’s also a good idea to periodically check the flapper and fill valve for signs of wear or damage. Finally, consider installing a low-flow toilet, which can help to conserve water and reduce the risk of a running toilet.

When to Call a Professional Plumber

While fixing a running toilet can be a DIY project, there are times when it’s best to call in a professional plumber. If you’ve tried to fix the problem yourself and it persists, or if you’re unsure about how to proceed, it’s best to leave it to the experts.

Our water heater began spewing water this morning.  John was the first plumber in the area to answer my call, and was able to get to my house within 10 minutes of the call.  He fixed the problem promptly and for what seemed to be a reasonable price.  He was friendly and informative.  I will definitely call John again and will recommend him to neighbors.  Thanks, John!

John has done numerous plumbing projects around my house and has always done excellent work.  He's quick to respond to my inquiry's and even replaced my water heater on a Sunday.  Most recently, I had him install a water purification system and new faucet.  His prices are reasonable and he will continue to be my go-to plumber.

Project: Install, Repair or Replace Plumbing or Fixtures

Comments: I am very pleased. I've had John do the top priority job of repairing a leaking drainpipe and his work looks to be top notch. I'm definitely thinking of using him for the larger job of repiping the whole house (replacing the failing M-type copper with L-type). And again, John's bid is within my budget considerations. Highly recommended.

Camera Locate Breakage for a Plumbing System

Comments: We had them run a snake from our sewer line out to the street, as we have lots of trees with roots that sometimes get into the line. They came as scheduled, did a great job and the price was as quoted.
