Understanding Pressure Gauges

Knowing how to read your pool filter pressure gauge and what to do if it’s not reading right can save you time and money. Most pools come with a pool filter pressure gauge; it’s the gadget that reads the amount of pressure building up inside the filter. Understanding this device is pivotal in keeping your pool healthy and safe.

You should get into the habit of checking your pressure gauge once a week. The typical swimming pool gauge is located on the top of the filter. It's a round device with numbers ranging from 0-60 divided into 10's or 5's by tick marks. The numbers represent the force of water flowing through your system in pounds per square inch or psi for short. Make sure you know what the normal operating pressure is (it should be recorded when a new pressure gauge is installed). Generally, your filter needs cleaning if the pressure rises more than 10 psi over the original marking. Double check in your owner’s manual if this guideline is right for your pool.
