Check that the water is the pessure cylinder to enough and when to pump enough circuit open circuit and wait for water, not enough again to close the circuit to put the magnetic contactor tag router running pump to use again.
pessure is enough to check that the water pump or cylinder port and circuit to open circuit. Wait for the water and not enough time to finalize the circuit so that a magnetic connector tractors to work the pump again.
Pessure a check that the water pump to pump enough enough and when the circuit is open circuit. And water enough again to close the circuit to ordered magnetic contactor work pumping to use again.
