If your toilet is constantly running, you’re not alone. A running toilet can waste gallons of water, increase your water bill, and be an annoying problem to deal with. The good news is that it’s a relatively easy issue to fix, even for beginners. In this complete guide, we will walk you through the steps of fixing a running toilet and help you understand why it happens in the first place.
Why Is Your Toilet Running?
Before diving into how to fix a running toilet, it’s important to understand why this issue occurs. A running toilet typically happens because of one or more issues in the internal components. Here are the most common causes:
- Flapper Valve Issues: The flapper is responsible for sealing the tank and allowing water to flow into the bowl. If the flapper is damaged or not sealing properly, water will keep running.
- Float Issues: The float controls the water level in the tank. If it’s set too high, water will continually overflow into the overflow tube, causing the toilet to run.
- Fill Valve Problems: If the fill valve is faulty, it may not shut off correctly, allowing water to flow constantly into the tank.
- Corroded Parts: Over time, parts like the flush valve or chain may corrode, causing the toilet to run.
Now that you know the potential causes, let’s walk through how to fix a running toilet with simple steps.
Step-by-Step Guide to Fix a Running Toilet
Fixing a running toilet can be a simple process if you follow these steps carefully. Before starting, make sure you have the necessary tools: a new flapper, fill valve, or any other replacement parts depending on the problem you identify.
1. Turn Off the Water Supply
Before making any repairs, you need to turn off the water supply to the toilet. Locate the shut-off valve behind the toilet near the wall and turn it clockwise until it’s completely closed. This will prevent water from flowing into the tank while you work.
2. Check the Flapper Valve
The most common cause of a running toilet is a worn-out or improperly seated flapper valve. To check it:
- Lift the toilet lid and flush the toilet. Look at the flapper at the bottom of the tank.
- If the flapper is damaged or doesn’t sit flat on the flush valve, you will need to replace it.
To replace the flapper, simply unhook it from the chain and remove it from the valve. Install the new flapper, adjust the chain length, and test it by flushing the toilet again.
3. Check the Float Level
The float is another common cause of a running toilet. If the float is too high, it will cause water to spill into the overflow tube, which leads to constant running. To adjust the float:
- Locate the float inside the tank. Depending on your toilet model, it may be a ball or a cylindrical float.
- If the float is too high, gently bend the arm downward or adjust the float’s position to lower the water level.
Once the float is adjusted, test the toilet by flushing and checking if the water stops running.
4. Inspect the Fill Valve
If the flapper and float are working correctly, but the toilet still runs, the issue may be with the fill valve. To inspect the fill valve:
- Turn off the water supply and flush the toilet to empty the tank.
- Examine the fill valve for any visible signs of damage or corrosion.
- If it appears damaged, you’ll need to replace it. A faulty fill valve may not shut off, causing water to continuously enter the tank.
To replace the fill valve, remove the old valve by unscrewing the nut holding it in place. Install the new valve according to the manufacturer’s instructions and reconnect the water supply.
5. Check for Leaks or Corrosion
Lastly, check for any signs of corrosion or leaks in the tank. Corroded parts or seals can prevent the toilet from functioning properly and cause it to run. If you see any corrosion on the flush valve or the fill valve, it’s best to replace those parts to prevent further issues.
6. Test the Toilet
Once you’ve addressed the flapper, float, and fill valve, turn the water supply back on and let the tank refill. Flush the toilet a few times to ensure the problem has been fixed. If everything works as it should, your toilet should no longer run continuously.
Additional Tips for Preventing Toilet Problems
To avoid dealing with a running toilet again in the future, here are some maintenance tips:
- Regular Inspections: Check the internal parts of your toilet regularly to ensure they’re functioning properly. Look for any signs of wear or damage and replace parts as needed.
- Avoid Harsh Cleaners: Don’t use harsh chemicals in your toilet, as they can corrode parts and cause leaks. Stick to gentle cleaners and disinfectants.
- Mind the Water Pressure: Excessive water pressure can strain toilet components. If you notice your toilet constantly running, it may be worth checking the water pressure in your home.
