What is the proper psi for a sand filter pool pump?

The proper PSI for a pool filter will vary based on the manufacturer and the type of filter being used. However, a good rule of thumb is to operate a sand filter pool pump at 10-15 PSI (pounds per square inch) below the maximum recommended PSI for your specific filter.

For example, if your pool filter recommends operating at 50 PSI, you would set the pump pressure to 35-40 PSI. This allows the filter to operate efficiently without putting excessive strain on the pump or filter media.

It is also important to monitor the pressure gauge on your pool pump regularly. If the pressure drops too low (below 10 PSI), the filter may not be able to effectively remove dirt and debris from the water. Conversely, if the pressure rises too high (above the maximum recommended PSI), it could damage the filter or pump.

By following these guidelines, you can help keep your pool filter operating efficiently and your pool water sparkling clean.
