Wax rings, seals, and gaskets help form water-tight connections to prevent leaks between and around toilet components. They're made of plastic or rubber and used as replacements for rings, seals, and gaskets that have deteriorated and started to leak. Wax rings seal the drainpipe connection between base of the toilet and the wall or floor. Signs that wax rings are failing include water seepage at the base of the toilet and unpleasant odors from sewer gas. Gaskets and seals seal the connection between the toilet tank and the bowl. They may need replacing when water leaks from the bottom of the tank.,Standard toilet repair parts are universal fittings, hardware, and accessories for fixing, mounting, or enhancing the utility of toilets. They're used on standardized components common to all types of toilets such as toilet seats, waste lines, and water-supply connections. These parts can replace broken components, seal leaks between connection points, secure fixtures to a floor or wall, and facilitate repairs.
