Abstract
A sanitary pump station for removing waste from recreational vehicle and pleasure craft waste tanks is provided. A pump station housing encloses a motor driven pump provided with at least a pair of one-way valve arrangements in both inlet and outlets to the pump. A waste hose is connected to the pump inlet and stored on a reel device within the housing. A water hose connected to an external water source is also provided. The water hose is also stored in the housing on a second reel. The respective hoses may be pulled from the housing, selectively, and after use, may be rewound on the reels by a rewind mechanism selectively engageable with drive pulleys associated with the respective reels. A universal adaptor is also provided to enable connection between the waste hose and the termination valve of the waste tank.
