The relief valve is how that air comes back out. Open it on startup and hold it open until water rather than air comes through, and the tank is full. Skip that step and the gauge reads low, the filter runs on a pocket of compressed air, and pressure can build in a way nobody wants near a plastic tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen it needs replacing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRelief valves live on top of the filter in full sun and get operated by hand several times a season. The seal hardens, the stem seizes or the body cracks, and it starts to drip whenever the pump runs. Tightening a weeping relief valve does not fix it and usually splits the body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eListed for the Jandy CS series cartridge filter.
