Heavy on the technical side...

Working Principle
As the pump runs, pressure is increased until it reaches the pre-defined pressure level. When the pre-defined pressure level is reached the integrated pressure switch automatically shuts the pump off.
The pump is equipped with positively checking outlet valves which ensure that the pressure is maintained after the pump shuts off.
When water is demanded (at the faucet, shower etc.) the pressure decreases. After a moderate drop in pressure, the integrated pressure switch automatically turns the pump back on. The pressure setting of this pump is factory set and cannot be changed without voiding the warranty.
As with all demand water pressure pumps, this pump is rated for intermittant duty (20 minutes maximum run time).
