A hydrostatic test pump is designed to test the pressure in a water or gas line up to 12,000 PSI to ensure the lines are safe from leaks. Once a line has been installed for a sprinkler or gas line the user will pump fluids into the line and build the pressure up to a specific PSI, the pressure is then held in the line to evaluate if the pressure remains constant. If there are no leaks the pressure will remain the same, leaks can be detected by a loss in pressure or using a leak detection device that can detect any air bubbles in the line.
How do you do a hydrostatic pressure test?
Do not use the pump to fill pipe that is to be tested.
Use only clean water and do not remove intake line strainer except to clean. Sand and other contaminants will damage the hydro pump.
When drawing water from a drum be sure the intake hose is not resting against the wall of the drum, restricting the intake suction.
Start your test by turning on the pump or manually start pumping to build pressure in the line
Stop the pump when you have reached your desired pressure or PSI on the pressure gauge
Lock the pressure in and wait to see if the pressure lessens and inspect the line for any leaks
If pressure remains constant the line is clear of leaks.
Do not use hose or fittings which are rated for less than the test pressure
Do not run this pump dry always have fluid when running it.
DO not tamper with engine setting.
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 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 inside.
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
