Abstract
A diverter valve housing is secured to an upper end of a pump. A shuttle in the diverter valve housing moves between an upper closed position and a lower open position. A floating ring has an exterior band that abuts an upper end of the shuttle to move the shuttle downward. The floating ring moves upward when the pump operates. A bushing abuts an upward facing shoulder in the floating ring and is adhered within the bushing by a layer of adhesive. The shuttle has upper and lower seals separated by upper and lower spacer rings. A stop ring between the spacer rings limits downward movement of the upper spacer ring and also limits upward movement of the lower spacer ring.
