Water Tank Pressure Switch Adjustment

The pressure tank should be set at 2 psi less than the cut on pressure.

Water tank pressure switch adjustment.

As you re adding air keep checking the tank air pressure with a tire gauge. Normally this switch is pre set to the correct pressure but you can modify it without any special tools or materials using just plumbers pliers. It makes use of two pressure systems to control the water flow and adjusting the water pressure involves adjusting these systems. Air can be added with a compressor or bicycle pump.

Check pressure in the tank with your pressure gauge. The well pump water pressure switch controls the rate at which the pump will turn on and off.

How to set the water pump cut in and cut out pressures. Here we are discussing setting the water pressures at which a water pump will turn on to get more water and off to stop pumping water from the water source into the water tank. Release or add air as necessary to make the pressure 2 psi below the pressure switch pump cut in setting. Even if the tank air pressure is too low you should still see some air pressure at the tank air valve when all water has left the tank.

In a bladder type water tank with proper pressure adjustment when all water has left the tank you ll see air pressure at 2 psi below the pressure switch cut in setting. The air in the tank should be 2 lbs less than the kick on pressure when the pump engages if you are currently at 18 lbs then adjust when the tank is completely drained of water if you are running 40 60 then you will want 38 lbs of air. If you adjust your cut on pressure you will also need to adjust the pressure tank air charge.
