The line should be filled by some other means. Do not use hydrostatic test pump to fill pipe that is to be tested.
Use only clean water in a hydrostatic test. Do not remove intake line strainer except to clean. Sand and other contaminants will damage the hydro pump.
When drawing water from a drum to conduct a hydrostatic testing, be sure the intake hose is not resting against the wall of the drum, restricting the intake suction.
Do not use hose or fittings which are rated for less than the test pressure being used on the test pump or the hand operated test pump.
Do not run this pump dry always have fluid when running a hydrostatic test.
DO not tamper with engine setting on the hydro pump.
Do not pump chlorine solutions, except for diaphragm hydro pumps. Chlorine can damage the pump and valve seals on the test pump. (With the exception of the diaphragm pump)
When you have finished using your hydro pump and are going to store it until your next job, we suggest running 50/50 water/antifreeze solution through it. This will lubricate your pump and prevent rust in the test pump
Piston roller test pumps are primarily used in testing water, landscaping, irrigation and plumbing lines. These units are dependable and simple to run, designed for testing lines up to 16 inch in diameter; with volumes up to 10 GPM and pressures up to 450 PSI
