Have you ever annoyed by a leaking toilet flapper? The sound of water running all the time. Also, extra water usage and the resultant added usage to your monthly bill. Here we are going to discuss how to fix a running toilet when it has flapper problem.
Leaking problems with an old flapper
- If the flapper is more than 5 years old, simply change it. The time saved will outweigh the cost of fussing with an aged flapper. Go to the parts of a toilet to find a similar flapper.
- If the flapper is less than 5 years old, check the rubber surface for debris. Wipe slime and/or debris from the underside and seat with a clean cloth.
- If the flat rubber piece is warped then replace it. If you use chlorine tablets in the tank this would be the cause of the warping.
- Cut excess chain if it is interfering with the seating of the flapper. Makes sure the chain is not too straight. It may lift the flapper from the seat. Have ¼”to ½” slack in chain.
how to test for a leaking toilet flapper
Listen for a constant, slow trickle — you may hear the toilet running if the flapper isn’t sealed completely. If there is a leak, you also might notice a slight increase in your water bill.
Remove the tank lid and lay it on a towel on the floor so it won’t get broken. Place a few drops of food coloring into your toilet tank. Don’t flush the toilet for 15 minutes. Check the toilet bowl — if any of the food coloring appears in the bowl, the flapper is leaking.
Inspect the toilet flapper. Turn off the valve that supplies water to the toilet — it’s usually found behind the toilet. Remove the tank lid and set it safely aside. Reach in the tank and pull the flapper up out of the water by its chain or plastic arms. Look for bumps and dirty or eroded areas on the bottom of the flapper — if the surface is uneven, the flapper won’t be able to lay flat and create a tight seal. You can try cleaning the bottom of the flapper, then turn the water back on to see if that solves the leak.
How to fix leaking toilet flapper
1. Turn Off the Water Supply
Before fixing the flapper valve, we need to turn off the toilet inlet valve behinds the toilet. Turn the handle clockwise until it stops turning to shut of the supply of water to the toilet tank.
2. Flush the toilet and empty the Tank
As the running toilet flapper is at the bottom of the tank. we need to flush the toilet and let the water in the tank out. The tank doesn’t need to be dry to replace the flapper, you just need make it so that you don’t have a tank full of water making things difficult for you.
3. Remove the Tank Lid
Lift and set it aside carefully. This piece is not reinforced porcelain, so take extra care when removing and setting it aside.
4. Remove the Chain
There is a chain or strap from lever attached to the flapper . Removing the chain on the lever.
5. Remove the Old Flapper
The flapper has 2 “ears” which hold on to the overflow tube. Pull the ears off and remove the old flapper from the tank. Place it in the garbage. Time tends to make these valves shed layers, so be careful. The coating they build up over time is difficult to remove from painted surfaces if it splatters.
6. Install the New Flapper
Place the ball portion of the flapper in the tank opening and put the ears on the overflow tube.
7. Reattach Actuator Pull Chain
Once the valve is in place and properly attached, you need to attach the chain that actuates it to the flush handle. You may have to adjust the length of the chain by moving it up or down the actuator arm.
8. Turn Water Supply On
Reach below and behind the toilet and turn the water supply valve, or angle stop, back on. Allow the toilet to fill. Replace the toilet tank lid very carefully in order to not break it.
9. Test the flapper working properly
Once the water level in the tank reaches the desired fill level, adjust the shutoff valve to maintain the proper level. Test your installation and the seal of the valve by flushing the toilet. Make sure the water turns off at the proper level and stays off. Wipe up any spilled or splashed water.
