7 Ways To Fix A Leaky Toilet Tank
Before we continue, it's recommended that you read our previous article on 'How to Detect A Leaky Toilet' in order to help you determine what's actually going on in and around your leaky toilet tank. If you're not sure how your toilet actually works, click here. Once that's settled, try out one of the following 7 possible fixes, ranked from least to most challenging.
1. If your leak is coming from where the tank and bowl connect:
If this is the issue with your leaky toilet tank, the fix involves simply tightening the nut or replacing the washer.
Find the nuts that connect the tank to the bowl.
Use a flathead screwdriver to steady the bolt.
Use an adjustable wrench to tighten the nut.
Replace the washers if water continues to seep out.
A leak springing from where the bowl and tank connect is a simple fix.
2 to 5. If your leak is coming from the handle:
Toilet tanks control water height by way of a float ball, a water-intake assembly, or a metered fill valve, and an issue with any of these may cause a leak from the toilet handle. Additionally, the overflow pipe may be too long. Here's what you can do.
- Check to see if the float ball is too high; if so, water is running into the overflow pipe and out of the handle.
- Bend the float ball arm down slightly so that the water comes up to about 1” below the overflow pipe.
- Flush the toilet to ensure that enough water gets into the bowl. If the water level is insufficient, then adjust the float ball arm up slightly until the tank fills with water.
- Lower the water level by adjusting the water-intake assembly.
- Pinch the clip attached to the thin metal rod.
- Slide the clip and the cup down to lower the water level. Move 1” at a time.
- Flush the toilet to ensure that enough water gets into the bowl. If the water level is not sufficient, adjust the cup slightly upward.
- Adjust the knob of the metered fill valve.
- Turn the knob counterclockwise 1/4 of a turn using a screwdriver.
- Adjust the knob 1/4 turn counterclockwise until the water is below the overflow pipe.
- Flush the toilet to ensure that enough water gets into the bowl. If the water level is insufficient, adjust the knob slightly clockwise until enough water fills the bowl.
- Check the overflow pipe.
- Check to be sure that the overflow pipe is 1/2” below the handle.
- Use a hacksaw to shorten the pipe, if needed.
The handle may be the culprit when dealing with a leaky toilet tank.
6. If you have a spraying refill tube
If your leaky toilet tank is the result of a spraying refill tube, simply replace the tube and cut it to the appropriate length to stop the spraying.
Replace the tube and cut it to the appropriate length to stop the spraying.
7. If your leaky toilet tank has an issue with the flush valve:
If you have a damaged flush valve, it will have to be replaced, and this means you actually have to move the leaky toilet tank. Again, contact the experts at WaterSmart if you need assistance.
Place towels on the floor to catch excess water.
Turn off the water supply to your toilet.
Flush your toilet to drain the tank.
Loosen the nuts for the supply tube using an adjustable wrench.
Loosen the nuts that hold the tank on the bowl, keeping the bolt stable with a flathead screwdriver.
Lift your tank off the bowl and place it on top of the towels that you have already laid out on the floor.
Replace the flush valve assembly by first removing the old flush valve assembly and unscrewing the locknut on the bottom of the tank.
Cut the pipe to 1/2” below the top of the tank using a hacksaw.
Place plumber’s putty on the washer at the foot of the new flush valve assembly.
Push the assembly against the tank opening. Scrape off any excess putty.
Tighten the locknut with a monkey wrench. Replace the gasket over the locknut.
Replace your tank by first placing the tank back on top of the bowl and tighten the nuts that connect it to the bowl.
Turn the water supply back on and fill the tank.
Flush the tank to ensure that the leak is gone.
Yes, this is quite a process, and we recommend calling a professional plumber to get the job done right.
The surest way to fix a leaky toilet tank is to call a professional plumber.
