• Also called a Flush Valve Seat Ball, this device sits on the flush valve seat and attaches to the trip lever with a chain, rod or guide arm.
• When the outside handle on the toilet tank is pressed down, it raises a trip lever that pulls the flapper off its seat. Water inside the tank pours through the opening to flush the toilet bowl.
• The valve stays closed with water pressure. However, once the trip lever lifts the device, it remains off the seat by floating on top of the water until the tank is empty. As the water level drops, the flapper gradually settles back into the opening, sealing it so the tank can refill for the next flush.
• A new style design has replaced the older ball-style. It is connected to the float arm with a chain and eliminates many of the problems associated with wires, rods and guide arms.
