How do I change the pressure setting of my well booster system? |Aquasky

Pressure switch settings are adjustable, and if the previous pressure setting doesn’t meet your requirement, you can adjust them to better suit your needs.

 

Please follow these steps.

Step 1-- Turn off power to the well pump.

By either unplugging the power cord from the wall outlet or turning off the circuit breaker.

 

Step 2--Drain the tank of water.

Before making any changes to the pressure settings, you’ll want to ensure the well tank itself has no water within it. This will make recalibrating the pressure of the well tank much easier.

 

Step 3--Find your pressure switch.

The pressure switch is a rectangular black box, usually attached to the tank manifold found at the base of your tank. It is usually found adjacent to the circular pressure gauge, the device that indicates the pressure of the water in the waterline.

 

Step 4--Remove the pressure switch’s cover.

The pressure switch’s cover is usually black or dark gray and is attached to the body of the switch by a nut. Using an adjustable wrench, loosen the nut and remove the cover from the switch. Many pressure switch manufacturers will include an internal diagram that shows demonstrates standard pressure switch settings, like 30/50, 40/60, or 20/40.

 

When you take the cover off the pressure switch, you’ll see two spring-loaded nuts. The larger, center nut controls the switch’s pressure range. If you tighten the center nut, you’ll increase the range. For example, the pressure switch was calibrated with a 30 psi cut-on and a 50-psi cut-off, tightening the nut could increase the range to 35 and 55.

 

The smaller nut located beside the larger nut adjusts the differential between the cut-on and cut-off pressure settings. If you tighten the small nut, you’ll increase the cut-off level while keeping the cut-on level at its original setting.

 

Step 5--Examine the pressure switch. ( Pressure difference )

Pressure switches will have nuts internally that can be rotated to modify the cut-on and cut-off pressure. Most commonly, pressure switches will use a single nut to raise both the cut-on and cut-off pressure simultaneously. This maintains the necessary 20 psi differential between the two pressure settings. The set relationship between the cut-on and cut-off pressure is crucial for the performance of your pump and well.

 

Step 6--Adjust the pressure settings with a wrench. ( Pressure range )

Using a wrench, turn the nut clockwise to raise the pressure and counter-clockwise to reduce the pressure. For every complete turn of the nut, the pressure increases

2- 1/2 psi. So, to raise the psi by 10, you will need to turn the nut three and a half times. If your pressure switch uses separate nuts to adjust the cut-on and cut-off pressures, consult the switch’s manual before attempting to adjust the pressures.

 

Step 7--Reset the well tank’s pressure.

Now that you have changed the pressure switch settings, you will need to change the pressure of the tank itself to support the pressure settings. Since the pressure of the tank needs to be 2 psi below the cut-on pressure, use an air compressor to raise the pressure. For example, if your well pump pressure control switch is set to "cut in" (start pumping water from the well) at 30 psi, then set the pressure tank to (30 - 2) = 28 psi. Periodically check the pressure with a tire pressure gauge, and add or release pressure until you’ve reached the desired threshold.

 

Note: Never set the cut-off pressure setting above 60 psi. Some commercial tanks are capable of withstanding higher pressures, but for the safety of your home, you should never let the cut-off setting exceed 60 psi. Pressures higher than 60 psi can damage your pipes, fittings, and switches. This damage can lead to plumbing failure and costly leaks. If the pressure is set at 80 psi, it’s very possible the pump will be unable to reach the cut-off pressure. By the same token, never set the cut-off setting below 20 psi.
