To troubleshoot a Square D Pumptrol, follow these steps:
1. Check the power supply: Ensure that the pump is receiving the correct voltage and that there are no power interruptions or wiring issues.
2. Inspect the pressure switch: Verify that the pressure switch is properly set and adjusted according to the manufacturer’s instructions. Check for any damage or signs of wear.
3. Test the contacts: Use a multimeter to check the continuity of the contacts in the pressure switch. If there is no continuity, it may indicate a faulty switch that needs to be replaced.
4. Examine the pressure tank: Inspect the pressure tank for any leaks or damage. Also, check the air pressure inside the tank to ensure it is within the recommended range.
5. Check the pump motor: Test the pump motor by listening for any unusual noises or vibrations. If there are any issues, the motor may need to be repaired or replaced.
6. Consult the user manual: If troubleshooting steps do not resolve the issue, refer to the user manual or contact Square D customer support for further assistance.
By following these troubleshooting steps, you can identify and resolve common issues with a Square D Pumptrol.
Square D Pumptrol pressure switches are used in various residential and commercial plumbing systems to regulate water pressure. Although these switches are usually reliable, issues can arise with the switch or the associated water system. If you encounter problems, troubleshooting can help you identify the cause and potentially save you money on a professional visit.
Step 1
Check that all fusible switches and circuit breakers providing power to the Pumptrol pressure switch are functional and switched “On”. Also, inspect the wires for cuts, pinches, or frays. If the switch still fails to operate once power is properly supplied, disconnect all power before continuing.
Step 2
Visually inspect the switch contacts for any severe burning or pitting. If these issues are present, replace the contacts with Square D part number 9998PC241 for 9013F models and part number 9998PC205 for 9013G models, as recommended by the manufacturer’s website.
Step 3
If the switch contacts are in good condition, ensure that the entry to the switch diaphragm is clear of debris, sand, or deposits. To do so, remove the switch body from the pipe and inspect the opening into the diaphragm located at the bottom of the switch body. Remove any obstructions.
Step 4
Reinstall the switch and check whether it operates correctly. If the switch seems to function but fails to maintain proper pressure, adjust the cut-in and/or cut-out settings.
Step 5
To maintain a constant differential between the cut-in and cut-out settings while adjusting these values, adjust the range nut. The range nut is the 3/8-inch nut that adjusts the larger of the two springs in Models FSG, FYG, FRG, and Type G Pumptrol switches. For example, turn the range nut clockwise to increase the cut-in pressure and counter-clockwise to decrease the cut-in pressure. Three and a half revolutions of the range nut will alter both the cut-in and cut-out settings by roughly 10 psi.
Step 6
To change the cut-out setting while retaining the cut-in pressure, adjust the differential nut. All Pumptrol models except FTG and FHG will have this option. The differential nut is the 3/8-inch nut that adjusts the smaller of the two springs in Models FSG, FYG, FRG, and Type G switches. For example, turn the differential nut clockwise to increase the cut-out pressure and counter-clockwise to decrease the cut-out pressure. Adjusting the differential nut will only change the cut-out setting while leaving the cut-in setting unchanged.
