Sell Water FLOW SWITCH Discount 1 -1/2 INCH Automatic SWITCH Pump Before SANWA Pump best price

Welcome. A flow switch is an automatic pump that works if there is water flowing, it will conduct electricity when the water flows and will decode the current if the water stops. It 's usually used for booster pumps, but it can also be used for shallow water pumps that are made booster. The booster pump on the market is quite high, so it 's common for people to use shallow water well pumps to make booster, but it' s a problem to buy a well pump that 's automatic to make booster. It can 't work to the maximum because it automatically uses a pressure switch that will cause the pump to die in a short time or usually people call it "print-check". So the solution is that you can use a NON-automatic shallow well pump, and use this device as an automation, the results that you get will be maximized by spending the economical money compared to buying booster pumps.
