Pressure Switch
Pump turns on automatically when tap is opened.
The pump can push water up to approximately 100 feet (30 meters), but its maximum suction capacity is limited to 25 feet (7.5 meters) horizontally and 6 feet (1.8 meters) vertically. To ensure optimal performance, it is recommended to keep the water line as short and as level as possible, and to avoid steep inclines.
We recommend using a 1/2-inch diameter hose with a total length of 25 feet between the water source and the showerhead or tap to ensure optimal water pressure. Using hoses with larger diameters, such as 5/8 inch or 3/4 inch, may result in reduced water pressure.
Yes, the pump is equipped with a pressure switch. This means that when a tap or showerhead is opened, the pump detects the drop in pressure and automatically starts pumping water.
This pump is designed for intermittent use only (maximum 15 minutes at a time). Continuous operation will reduce the pump’s lifespan and is not covered under the warranty.
