How to Repair a Peerless Toilet Tank
Peerless toilets are easy for anyone to repair. The most common problem with Peerless toilets is water continually running from the tank into the bowl. If you notice this with your toilet, the flapper inside of the toilet is defective and needs to be replaced. Any local hardware store or plumbing supply company will carry a universal replacement flapper that will fit your Peerless toilet tank.
