Finally, attach the fill tube hose to the overflow tube.
TOILET OVERFLOW TUBE AND FLAPPER ASSEMBLY INSTALL
Install a new fill valve assembly and reattach the supply line. Disconnect the supply line, and remove the nut on the bottom of the tank to remove the old fill valve assembly. Sponge the final few cups of water from the bottom of the tank. Shut off the water supply to the toilet and flush to empty the tank. Step 6: If that doesn't stop the leak, replace the fill valve.First, try to adjust the float level so the water stops flowing before reaching the overflow level. If the water level in the tank is up to the top of the overflow tube, you probably have a fill valve problem. In this case, a steady trickle of water will run constantly, flowing into the overflow tube in the toilet tank. Step 5: If the toilet is still leaking, you may have a problem with the fill valve.If necessary, gently pull the small tube upward until its end is correctly placed. Step 4: Inspect the small refill tube that connects the fill valve to the refill-overflow tube to be sure the smaller tube ends slightly above the standing water level of the filled tank.Check for corrosion or deposits on the seat and the ball stopper or flapper valve. If the ball or flapper valve itself is worn out, replace it. For toilets with a chain pull attached to the flapper valve, make sure the chain is slack when the valve is seated to ensure a snug fit. If they are crooked, gently straighten them. If not, look at the lever and guide rods that operate the ball stopper. Step 3: If the toilet periodically refills without flushing, examine the ball stopper or flapper valve.If it’s slightly damaged or worn, replace it. Examine the inlet float valve by removing the two screws or bolts and lifting the top of the valve housing out.
