RV Dual Action Low Boy RV Water Pump  131-5This attractive water fixture offers the convenience of three water pumps in one fixture:1. A full stroke of the handle up and down causes the fixture to function as a hand pump providing greater water flow with minimum effort. 2. To lift the handle to the up position activates an electric water pump to produce a smooth flow of water. 3. To press the handle to the down position delivers city water. The Low Boy is often used where clearance is a factor, such as in a folding trailer.
