A leaking toilet tank can be a frustrating and wasteful problem. Not only does it waste water, but it can also lead to higher water bills and potential damage to your bathroom floor.
Fortunately, fixing a leaking toilet tank is a manageable DIY task that you can accomplish with a few tools and some basic knowledge. In this guide, we will provide step-by-step instructions on how to address this common issue.
Step 1: Identify the Source of the Leak
Before you can fix the leak, you need to determine where it’s coming from. Common sources of toilet tank leaks include:
- Fill Valve: The valve that refills the tank after flushing.
- Flush Valve: The valve that releases water from the tank into the bowl.
- Tank Bolts: The bolts that secure the tank to the bowl.
- Cracks in the Tank: Visible cracks that can cause water to seep out.
Inspect the tank and surrounding areas carefully to pinpoint the exact location of the leak. You may need to flush the toilet a few times and check for drips or water pooling around the base.
Step 2: Turn Off the Water Supply
Once you’ve identified the source of the leak, the next step is to turn off the water supply to the toilet. Locate the shut-off valve, typically found on the wall behind the toilet, and turn it clockwise to close it. This will prevent any more water from entering the tank while you work on the repair.
Step 3: Drain the Tank
Flush the toilet to drain as much water as possible from the tank. Hold down the flush lever to ensure that most of the water is emptied out. Use a sponge or a towel to soak up any remaining water in the tank.
Step 4: Fix or Replace the Fill Valve
If the leak is coming from the fill valve, you may need to adjust, repair, or replace it. Here’s how:
Adjust the Fill Valve: Sometimes, simply adjusting the fill valve can stop the leak. Check the float and ensure it’s not set too high. Lowering the float level can reduce the water level in the tank, preventing overflow.
Replace the Fill Valve: If adjusting doesn’t work, you may need to replace the fill valve. To do this:
- Disconnect the water supply line from the fill valve.
- Remove the old fill valve by unscrewing the locknut underneath the tank.
- Install the new fill valve according to the manufacturer’s instructions.
- Reconnect the water supply line and turn the water back on to test for leaks.

Step 5: Fix or Replace the Flush Valve
If the leak is due to a faulty flush valve, follow these steps:
Inspect the Flapper: The flapper is a rubber seal that covers the flush valve opening. If it’s worn out or damaged, it can cause leaks. Replace the flapper if necessary.
Replace the Flush Valve: If the flapper replacement doesn’t fix the leak, you may need to replace the entire flush valve assembly. To do this:
- Remove the tank from the bowl by unscrewing the tank bolts.
- Take out the old flush valve and install a new one according to the manufacturer’s instructions.
- Reattach the tank to the bowl and tighten the tank bolts evenly.
Step 6: Tighten or Replace Tank Bolts
Leaking tank bolts can cause water to seep from the tank. Here’s how to address this issue:
Tighten the Bolts: Use a wrench to tighten the bolts evenly. Be careful not to overtighten, as this can crack the porcelain.
Replace the Bolts and Gaskets: If tightening doesn’t stop the leak, replace the bolts and gaskets. To do this:
- Drain the tank and remove it from the bowl.
- Remove the old bolts and gaskets.
- Install new bolts and gaskets, ensuring they are aligned properly.
- Reattach the tank to the bowl and tighten the bolts evenly.
Step 7: Repair Cracks in the Tank
If you discover cracks in the tank, you may need to repair or replace it. Small hairline cracks can sometimes be sealed with a waterproof epoxy. For larger cracks, it’s best to replace the tank entirely.
Step 8: Test the Repair
Once you’ve completed the repair, turn the water supply back on and let the tank fill.
Check for any leaks around the fill valve, flush valve, and tank bolts. Flush the toilet several times to ensure everything is working properly and no leaks are present.
