Powered by a cordless drill to keep weight off this test pump, the included hose (with quick disconnect feature) permits the pump to be set near the work instead of being held close to the work. Reed’s new DPHTP500 uses a corded drill with 1/2” chuck or 1/2” cordless 18V or higher drill capable of 1,500 RPM (drill not included). The pump supports the drill motor in forward or reverse, saving the life of the drill. These pumps are designed for pressure testing both residential and commercial water systems and have a capacity of 500 psi and 1.3 gpm.
