The Reed Electric Hydrostatic Test Pump offers a smooth running 3/4 HP quiet motor. The pump is designed for pressure testing water systems such as water meters, plumbing lines, pressure vessels, solar systems and sprinkler systems in both commercial and residential buildings. The output pressure is adjusted by easily turning a knob and watching the attached gauge. A built-in bypass allows for automatic water recirculation once the set pressure is reached. The hose-to-pump connection offers a quick disconnect with a built-in check valve to allow for easy setup and portability. The durable pump has a stainless steel piston and brass cylinder for longer life. Replacement kits are available to sustain the efficiency of the pump.
