If you are the owner of a swimming pool, ensuring your pool filter operates at optimal pressure is crucial. Knowing what your pool’s PSI (Pounds per Square Inch) should be is the key to the proper functioning of your swimming pool filter. In this article, we’ll provide comprehensive details on what PSI is and what it means for your swimming pool, as well as tips on how to check and adjust the PSI on your pool filter.

What is PSI?

PSI, or “Pounds per Square Inch,” is the unit of measurement used to assess the water pressure in various systems, including swimming pool filters. Simply put, it is an expression used to signify the amount of pressure that is required to maintain the operation of a machine, such as a pool filter system. As pool water flows into the filter, pressure builds up, allowing the filter to trap debris and other unwanted particles.

What should My Pool’s PSI be?

The ideal PSI range for your swimming pool in-ground or above is between 10 and 20 PSI when your filter is operating, however, the target PSI value will vary based on your pool’s make and model. A higher PSI value indicates that your pool’s water is struggling to flow freely, indicating a dirty or clogged filter. A PSI reading that is too low means that water’s water flow rate is not optimal, which can affect overall water quality and reduce the lifespan of your pool pump.

How to check my pool filter PSI?

Easily access and monitor your Swimming Pool filter PSI by following the steps below;

1. Find the PSI gauge: The PSI gauge is typically located at the top of the filter near the pump.

2. Turn off the pool filter: Turn the pool filter off before you check the PSI meter to get an accurate reading.

3. Look at the PSI gauge: Check the PSI gauge indicated on the meter on the filter system. The PSI reading will indicate your current PSI value.

If your PSI reading is below the recommended range, your pool filter may not be filtering your pool water as efficiently as it should, in this case, it’s time for a deep pool filter cleaning.

How to adjust my pool filter PSI?

Adjusting pool filter PSI is not difficult - it can be done in a few simple steps. Here are five tips for adjusting your pool filter PSI;

1. Check the Filter Basket: The filter basket on your pool filter plays an important role in maintaining a working PSI. Make sure it is cleaned and emptied regularly.

2. Check the Pool Pump: It’s important to ensure that your pool pump is well-maintained and working correctly. Check if the impeller is turning freely or if there is debris blocking the pool pump.

3. Backwash the Pool Filter: Backwashing your swimming pool filter should help lower the PSI value. If the PSI value persists even after backwashing, it may be time for a filter cleaning.

4. Inspect Pool Filter for Damage: The filter itself should be checked for any signs of damage, cracks or deterioration. A damaged pool filter can indicate that it’s time to invest in a new one.

5. Consult your Pool Pump & Filter User Manual: If you are unsure how to adjust your pool filter PSI, it's a good idea to refer to your Pool Pump and Filter User Manual for guidance.

Final thoughts

Ensuring your pool is maintained at optimal PSI can impact your pool’s overall water quality and the longevity of your pool filter system. We hope that this article provided useful insights on why PSI matters, how to check and adjust it, and how often to perform maintenance. Remember, proper pool maintenance is essential to the lifespan of your pool and its equipment, which should ultimately reduce maintenance and repair costs in the long run.
