How to Measure and Adjust Your Pool Pump Pressure

Properly measuring and adjusting your pool pump pressure is essential to ensuring the efficient operation of your poolโ€™s filtration system. The first step is to measure the current pressure using a pool pressure gauge, which should be installed on the filter tank. The pressure gauge measures the water pressure in pounds per square inch (psi), which indicates the resistance the water encounters as it passes through the filter. Ideally, the pressure should be within the manufacturerโ€™s recommended range for your particular pool system. If the pressure is too high or too low, adjustments will be necessary.

Adjusting your pool pump pressure can be done by cleaning or replacing the filter, backwashing the filter, or adjusting the valve settings on your pool system. When cleaning or replacing the filter, be sure to follow the manufacturerโ€™s instructions and use the correct replacement parts. Backwashing the filter involves reversing the flow of water through the filter, which flushes out any trapped debris. Adjusting the valve settings on your pool system can also help regulate the pressure, and may require the assistance of a professional.

Backwashing Your Pool Filter

  • Turn off the pool pump.
  • Move the multiport valve to the “backwash” position.
  • Turn on the pool pump and run it for 2-3 minutes or until the water in the sight glass is clear.
  • Turn off the pool pump.
  • Move the multiport valve to the “rinse” position.
  • Turn on the pool pump and run it for 30 seconds.
  • Turn off the pool pump.
  • Move the multiport valve back to the “filter” position.
  • Turn on the pool pump and resume normal operation.

Adjusting Your Pool Valve Settings

If adjusting the valve settings on your pool system, itโ€™s important to understand the purpose of each setting. The “filter” setting allows water to pass through the filter, while the “backwash” setting reverses the flow of water to flush out debris. The “rinse” setting is used to settle the filter bed after backwashing, and the “waste” setting allows water to bypass the filter and drain from the pool. Consult your pool systemโ€™s manual for specific instructions on how to adjust the valve settings.

By properly measuring and adjusting your pool pump pressure, you can ensure the efficient operation of your poolโ€™s filtration system and extend the life of your pool equipment.
