Fixing a Leaky Floatcup Assembly

 
A floatcup assembly is the part of your toilet that seals the opening between the tank and the toilet bowl. When the toilet is flushed, a rubber tank ball or flapper lifts out of the way and water rushes into the bowl. After a few seconds, the tank ball settles back down on the hole, sealing it and allowing the tank to refill. An old, worn tank ball or flapper is prone to leaks. The best way to fix it is to replace it.
 

 

Adjust the tank ball (or flapper) so it is directly over the flush valve. The tank ball has a guide arm that can be loosened so that the tank ball can be repositioned. Some tank balls have a ball guide that helps seat the tank ball into the flush valve. Make sure these parts are lined up and working smoothly. Turn off the water and flush toilet to empty tank.

 

 

 

 

Replace the tank ball if it is cracked or worn. Tank balls have a threaded fitting that screws onto the lift wire. Clean the opening of the flush valve using emery cloth (for brass valves) or a scrub pad (for plastic valves).

 

 

 

 

Replace the flapper if it is cracked or worn. Flappers are attached to the small lugs on the sides of the overflow pipe. Turn the water back on.
