A malfunctioning flapper can lead to a leaky toilet, wasting water and increasing your utility bills. Replacing the flapper is a relatively simple task that can be completed in a few minutes. This step-by-step guide will walk you through the process of replacing a flapper in a toilet tank.
Materials You’ll Need
- New flapper valve
- Adjustable wrench or pliers
- Screwdriver (optional)
Step 1: Turn Off the Water Supply
Locate the water supply valve behind the toilet and turn it off clockwise. This will stop the water from flowing into the tank.
Step 2: Flush the Toilet
Flush the toilet to empty the tank. This will make it easier to work on the flapper.
Step 3: Remove the Old Flapper
- Chain-operated flappers: Grip the handle of the flapper chain and pull it up to detach the chain from the flush valve. Then, unhook the flapper from the overflow tube.
- Lever-operated flappers: Use an adjustable wrench or pliers to loosen the nut that holds the flapper in place. Then, lift the flapper off the flush valve.
Step 4: Clean the Flush Valve
Use a damp cloth to clean any debris or mineral buildup from the flush valve. This will ensure a good seal for the new flapper.
Step 5: Install the New Flapper
- Chain-operated flappers: Hook the new flapper onto the overflow tube and then attach the chain to the flush valve. Adjust the length of the chain so that the flapper sits about 1/2 inch above the flush valve when it’s closed.
- Lever-operated flappers: Place the new flapper over the flush valve and tighten the nut until it’s snug.
Step 6: Adjust the Flapper
- Chain-operated flappers: Adjust the height of the flapper by moving the hook on the overflow tube.
- Lever-operated flappers: Adjust the position of the flapper by turning the adjustment screw on the flush valve.
Step 7: Turn On the Water Supply
Turn the water supply valve back on counterclockwise. Wait for the tank to fill up.
Step 8: Check for Leaks
Once the tank is full, flush the toilet and check for any leaks around the flapper. If you notice any leaks, adjust the flapper as needed.
Troubleshooting Tips
- Flapper won’t close: The flapper may be too low or the chain may be too short. Adjust the height of the flapper or lengthen the chain.
- Flapper won’t open: The flapper may be too high or the chain may be too long. Adjust the height of the flapper or shorten the chain.
- Toilet runs continuously: The flapper may be worn or damaged. Replace the flapper.
