Pumps, including suction and booster pumps, run idle when there is little or no water. This leads to malfunctions ranging from wear and tear of chamber parts to burnout of the pump.
Unless it's an announced water cut, or you'd have to check constantly to see if there is enough water in your water tank–which could be quite inconvenient.
Pumps in Walrus' TS_B and HS_B series are all designed with low-water cut-offs. The design prolongs the life of the pumps and makes your life easier. Moreover, if you live in an old building or can't seem to find a solution to the water leaks in your home, try our TQC_B or HQC_B series, which are installed on rooftops for automatic flow control. The design prevents the building up of continual pressure in your water pipes and the pump won't be activated frequently by the leaks in your home.
