Can anyone tell me how to install a household water pipe pump?

1. First determine the height of the lowest water level. If the height difference between the self-priming pump and the water level is greater than 10 meters, theoretically it will not be able to suction it up. It's actually 8.9 meters. If it exceeds the limit, a booster pump should be used.

2. Secondly, if the pipeline is filled with water and the water pump is started at the power frequency, water hammer is inevitable.

3. Finally, there is no need to use valve 1 because there is a faucet that can be closed. Valve 2.3 should use a check valve, so that it does not need to be opened and closed every time it works.
