The Hydro-Test Unit allows for simple and convenient hydrostatic pressure testing of virtually any piping system, but is specifically designed to pressure test unicoils before installation. The Hydro-Test Unit is a trigger operated electric test pump, complete with 10' discharge hose, and carrying case. Unique design allows for garden hose inlet to flush loop before pressure testing. Once the loop is filled and flushed, the Hydro-Test Unit can build up to 225 psi in seconds. Hydrostatic testing is the best and safest way to pressure test piping systems, and the Hydro-Test Unit is the simplest and most convenient way to do so.

Operation is simple. A garden hose is connected to the pump inlet and used to fill and flush the loop. Once the loop is full, the valve on the discharge adapter is closed and the loop is brought to line pressure. By simply pulling the trigger on the pump, you can boost pressure to 100 psi, and even higher, in seconds. There is an adjustable pressure relief valve to prevent over pressurization.

The supply and discharge adapters provide simple connection to the loop for pressure testing. The supply adapter provides a simple transition from the hose to the loop using quick connect couplings. It also has a shut-off valve as well as 1/4" pressure release valve. The discharge adapter has a shut-off valve as well as a pressure gauge for accurate pressure measurement. The test cap adapters quickly and easily seal the ends of the loop and have quick connections to the supply and discharge adapters. Test cap adapters are available in ¾' , 1", 1 ¼", 1 ½" ", and 2". If required, other types of adapters can be fabricated for larger diameter pipe.
