Product Usage

1.The automatic water supply of the tap water pipeline does not require an elevated water tank. It directly pressurizes the entire building's water supply, and the pressure is stable. It is more suitable for pressurization on water heater pipelines with insufficient water pressure. The water supply will not fluctuate between cold and hot, and can supply water to multiple households' faucets.

2.The automatic water supply system for underground and open-air wells can be used for shallow wells with a water level of no less than 8 meters, and can be transported to residential faucets without the need for water supply. It can also meet the water supply needs of two or three story residential buildings.

3.Insufficient water pressure in household water storage tanks can greatly increase water pressure and maintain stable water pressure.

4.The room heating water circulation is used for solar water heaters used in residential buildings, apartments, schools, high-end villas, hotels, canteens, domestic boilers, etc., as well as for supplying water to domestic boilers.

5.High rise residents can directly install self-priming pumps indoors. The self-priming pump has an 8-meter suction range. As long as this pump is installed indoors, high-rise residents can easily suck up the tap water from upstairs, and the water output is strong and powerful.
