Do you need a stop valve for the pump at home?
Pump used at home do not take the water stop valve, the water level is too low, it can not pump up. In addition, there is no stop valve, not immediately pumping water, will have to wait a short time.The valve is actually a floating ball valve, when water is accumulated to a certain height, the float top, open the valve linkage; row water, reduce the water level, the valve is automatically closed, it realizes automatic drainage to steam pipeline.
Must be connected, in the low-end water pipe, the valve is also called the bottom valve is to prevent the intrusion of water, at the same time, but also to ensure the pump again next time when starting the pump and piping in enough water to prevent idling.
It is better to connect with the pump. If it is a self suction pump, it can not be connected, but when it is pumped, it does not immediately have water, and the submersible pump is not necessaryMy home is a self suction pump, fully automatic control, I took the check valve, in the pump suction port position is very good, as long as it has started, there will be water out
