Gauge reads low sand filter pressure

[MarcsPool]

My psi is about half of what is normally is. I have strong pressure coming from jets. I checked skimmer pressure using the ‘min/max’ pressure gauge you get with the Hayward Ultra Vac vacuum and its reads over ‘max’. Both baskets are clear. Everything looks and acts and sounds normal. I’m thinking it’s a faulty gauge but wanted some experienced opinions. Thanks.

Remove the gauge, with your pump stopped, and clean the orifice in the filter and gauge. You may have some grains of sand blocking the gauge.

Does the gauge go to 0 when the pump is stopped?

No it doesn’t but cleaning out the orifice fixed it! Thank you so much. I wish I would’ve found TFP 20 years ago. Thanks again.

If the gauge does not go to 0 when the pump is off it should be replaced as it is inaccurate.
