• Economical, reliable pump is designed for pressure tests up to 300 psi
• Manual pump is budget friendly for occasional testing
• Pumps are self-priming and work with pressurized or non-pressurized water supply
• For more frequent system tests, consider REED EHTP500 and DPHTP500 power pumps
• Pump consists of a durable aluminum housing, steel pump handle and piston, plus stainless steel springs and ball bearings

Hydrostatic test pumps are designed to test water meters, plumbing lines, pressure vessels, solar systems and sprinkler systems, in both residential and commercial buildings. The test pumps are portable and can be used to test modest irrigation lines. Pump operation requires the user to first fill the system that needs to be tested. Next, the user raises the system pressure by actuating the test pump handle. Finally, the user closes the pump's ball valve at the desired pressure. The user determines leakage-based on dropping pressure as indicated by the hydrostatic test pump's pressure gauge. The pump has a relief valve that reduces the likelihood of over pressuring the system. Hoses are sold separately.
