Leaking Filter

[f30er]

My filter is dripping on top at the pressure relief looking valve. Filter pressure is reading 10psi. It's a Sta-rite System3 S7M120.
Any ideas?

If opening and closing the valve doesn’t stop the leak then it may have been damaged over winter. It probably needs to be replaced. See INYO Pools for parts -

Also, you may be able to completely unscrewed the Open/Close knob and remove it from the valve body. Check to see if the rubber o-ring at the end is chewed up or damaged. You may be able to replace the o-ring.

Nope opening and closing didn't stop it. Will check the o-ring but that gauge is brand new. I installed the whole thing less than a month ago. We did have a pretty cold spell for a few days so hoping that didn't damage it.
