A customer needed his toilet flapper replaced because his toilet was constantly running. Not only is that an annoyance, but it wastes money. Replacing the flapper can help get your toilet back to working normally.
If you notice that your toilet runs constantly and think the flapper may be the cause, you can use these tips to try and fix it:
- Lift open the tank and look inside. You should see a white plastic tube called an overflow tube. Attached to it near the bottom, you’ll see the flapper guides – two arms that hold either side of the rubber flapper. Attached to the guide arms is the flapper – a round piece of rubber that is supposed to fit tightly in a hole in the bottom of the tank. Attached to the top of the flapper will be a chain or metal rod. The chain is hooked to a bar at the top of the tank. There is another rob in the toilet that turns the flow of water into the tank on and off.
- Flush the toilet and watch what happens inside. When you push down on the flush handle, you should see the flapper come out of the hole. The flapper should float for a moment, but as water drains out, it will settle back into the hole. After the flapper closes the hole, the toilet fills with water.
- Replace the chain or wire on the lift bar if the flapper doesn’t lift off the hole. Use the middle hole first. Try another if the flapper doesn’t seal right.
- Untangle any kinks in a flapper chain if it’s still not fitting right.
- Adjust the length of the flapper chain so it doesn’t go into the hole with the flapper, preventing it from sealing. To do this: Move the hook on the chain to a different hole on the bar, or move the hook on the chain down further to shorten it.
- If it’s a wire, move the wire connected to the flapper to a different hole in the bar to see if that fixes the problem.
