How to Repair a Leaking Pull Chain Toilet
Repairing a leaking pull chain toilet may not be the most interesting job to do but since the bathroom is one of the most important rooms in the house, you have to what you have to do. To repair a leaking pull chain toilet, here is what you should do.
Step 1 – Get the Repair Area Ready
Remove items around the bowl to get some space to move around. Wipe off any water spill on the floor tiles to remove any potential hazard of slipping.
Step 2 – Check Toilet Tank Water Level
Carefully take the top off the toilet tank and look for the overflow tube. When water level gets too high in the tank, it will overflow at the top of the overflow tube and drain into your toilet bowl.
Listen for any sound of water running or overflowing into the tube. Lift up the float. You should hear the sound stop as it shuts off the toilet fill valve. The float automatically stops the water from feeding into the tank when it becomes full.
Step 3 – Adjust the Float Level
If the water stops when the float is lifted, adjust the float level so it shuts off water at the adjusted level – which should be lower than the overflow tube. The float can be a plastic ball on the end of a metal rod. It can also be a plastic cylinder that slides down or up via a plastic shaft.
Adjust the plastic-ball type by turning the adjusting screw at the end of the rod opposite the float. For the cylindrical-float type, find the thin metal rod which connects the float to a valve-arm. Move the adjusting clip by pinching the float to move further down in the water. Flush the toilet after making adjustment to the float and observe the tank as it refills. Ideally the valve will shut off when the level of the water is about an inch below the top of the overflow tube. Readjust the float if needed.
Step 4 – Flapper Cleaning or Replacement
If the problem is not about water overflowing into the overflow tube, the problem is on the flapper, at the bottom of the tank. When the flapper leaks, the tank water level goes down until the float drops down below its setting and water starts to refill the tank.
Check the pull-chain if partially lifting the flapper. Adjust this by loosening the chain to give enough length to let the flapper sit fully at the bottom. The pull-chain should show some slack. Shut off the main water supply valve to prevent continuous supply of water. Flush out remaining water inside the tank. Check for mineral deposits that lodge along the sides of the flapper causing water to pass through. Clean it gently using water and a scrubbing sponge.
Check flapper to see if it's worn out or warped. If so, buy a replacement of this from the hardware store.
Step 5 – Finishing Up
After making repairs, turn the shut off valve on. If leaks persist, close the shut off valve and prepare to replace your toilet with a new one.
