Hey there! As a supplier of Submersible Borehole Pumps, I've seen firsthand how important it is to keep these pumps running smoothly. One key aspect of maintaining your submersible borehole pump is adjusting the pressure switch correctly. In this blog, I'll walk you through the process step by step.
First off, let's understand what a pressure switch does. The pressure switch in a submersible borehole pump is like the brain that controls when the pump turns on and off. It senses the pressure in the water system. When the pressure drops below a certain level (the cut - in pressure), it tells the pump to start pumping water. And when the pressure reaches a set upper limit (the cut - out pressure), it shuts the pump off.
Why Adjust the Pressure Switch?
There are several reasons you might need to adjust the pressure switch. Maybe you've changed the water usage in your home or business, and the current settings aren't giving you the right water pressure. Or perhaps the pump has been acting up, cycling on and off too frequently, which could be a sign that the pressure switch needs some tweaking.
Tools You'll Need
Before you start adjusting the pressure switch, gather the following tools:
- A screwdriver (usually a flat - head or Phillips, depending on the switch)
- A pressure gauge to measure the water pressure accurately
Step 1: Locate the Pressure Switch
The pressure switch is typically located near the pressure tank of your water system. It's a small box - like device with wires connected to it. Once you've found it, make sure the pump is turned off. Safety first, folks! You don't want to get electrocuted or have water spraying everywhere while you're working on the switch.
Step 2: Check the Current Settings
Use the pressure gauge to measure the current cut - in and cut - out pressures. The cut - in pressure is the point at which the pump starts, and the cut - out pressure is when it stops. Most pressure switches have a label that shows the factory - set pressures, but over time, these can change.
Step 3: Adjust the Cut - In Pressure
To adjust the cut - in pressure, look for a large nut or screw on the pressure switch. This is usually labeled as the “cut - in” adjustment. Loosen the lock nut (if there is one) and then turn the adjustment screw. Turning it clockwise will increase the cut - in pressure, while turning it counter - clockwise will decrease it. Make small adjustments and then use the pressure gauge to check the new pressure.
Step 4: Adjust the Cut - Out Pressure
The cut - out pressure adjustment is often a smaller nut or screw on the pressure switch, sometimes labeled “cut - out.” Similar to the cut - in adjustment, loosen the lock nut (if present) and turn the screw. Turning it clockwise will raise the cut - out pressure, and counter - clockwise will lower it. Remember, the difference between the cut - in and cut - out pressures is called the “pressure differential,” and you want to keep this within a reasonable range.
Step 5: Recheck and Fine - Tune
After making the initial adjustments, turn the pump back on and let it run until it reaches the cut - out pressure. Then, let the water pressure drop until the pump kicks back in. Use the pressure gauge to double - check the new cut - in and cut - out pressures. If they're not exactly where you want them, make some more small adjustments and repeat the process until you get the desired pressures.
Tips and Tricks
- Don't make large adjustments all at once. Small changes are easier to control and will help you avoid overshooting the desired pressures.
- If you're not sure what pressures to set, consult the pump's manual or a professional plumber.
- Keep an eye on the pump's performance after adjusting the pressure switch. If it still seems to be having issues, there could be other problems with the pump or the water system.
