Pressure Control JH-2B
Description:
The Pressure Controls are completely silent and are designed to provide an automatic supply of clean water to one or two dwellings.
The Pressure Controller orders the automatic start and stop of the water pump when opening or closing any tap or valve of the system. The controller can keep constant pressure and water flow in the system as long as any tap in the system is open during the pumps operation.
It allows the pump to run at a constant flow. The controller stops rapid cycling of your pump unit, eliminating water fluctuating through your home.
