Press Control Pump Controllers Descriptions
This automatic pumpo control is mainly used in household for controlling the running of pump.Joint screw:G1″male
1.It start the electric pump automatically after a pressure decrease(taps opening)and stops it when the fluid flow interrupts at the maximum pressure level of the electric pump(taps closed),keep the household water supply system in water supply state with a constant pressure.
2.Protect the pump, in the case of water shortage or jam,it is able to indentify these fault and at the same time stop the pump

Water Pump Pressure Switch Safety Warnings
The following safety warnings emerged from responding to reader questions about adjusting the water pump pressure control switch:
Watch out: don’t run the water pressure control with too narrow a differential between the cut-in and cut-out or the pump may just sit there short-cycling until you burn up the motor. If your pump is staying on for less than 30 seconds (I prefer longer), you may be heading for trouble.
Watch out: setting the cut-out water pressure too high can cause the pump to never turn off or at high pressures you may find leaks at fixtures. And high water pressure that exceeds the rated water tank pressure can burst the tank – a very dangerous event. Also make sure your pressure tank has a relief valve installed.
Watch out: do not try setting up the pressure on the pump pressure control switch in this case. Since your pump is tripping the circuit breaker there is a problem to find and fix first: such as a failing pump motor, wiring error, or other unsafe condition.
The pressure control switch sets the water pressure at which your pump turns on and off. Typically these switches are set to turn on at 20 and off at 40 psi or on at 30 and off at 50 psi.
If your neighbor set the pump cut-out pressure too high, your water pump may simply be unable to ever reach the “Cut off” pressure – so the pump will run until it overheats and shuts off by an internal thermal overload switch. Usually these switches reset automatically when the pump cools down.
But running the pump this way is
– DANGEROUS – too much pressure could burst a water pressure tank or other plumbing parts, even injuring someone
– and it can ruin your well pump by burning out the motor
You need help from someone with a bit more expertise, perhaps a real plumber who knows how to adjust the pump pressure control correctly.
Watch out: messing with a pump pressure control switch exposes live electrical connections – you can be killed if you touch live wires. Another catastrophe to avoid is setting the pressure too high, causing leaks or worse, a burst water tank that could injure anyone nearby.
Watch out: If the clicking pressure switch is switching the pump on and off very rapidly, say every second, TURN THE PUMP CIRCUIT OFF immediately to avoid damaging the equipment. Then check for a clogged water filter, a water valve that should be open is closed, or a waterlogged preside tank
Watch out: I wouldn’t keep pressing on the relay. There’s live 120V or 240V in that switch – touching exposed wires or connectors is asking for a potentially fatal shock. Keep me posted, what we learn will help other readers.
