Can a leaking Jandy "Check Valve" with clear top be "fixed"?

[Poconos]

I know nothing about this particular valve, in fact I never saw one like this. Anyhow, anything that has screws for disassembly should be able to be fixed if nothing is broken. Looks like maybe a simple gasket replacement. Have you tried torqueing the screws to see if that stops the leak? The sequence for tightening on anything with a circular pattern is: label the screws 1 --> 8 in order. Then tighten in this order: 1,5,2,7,4,8,3,7. Also don't go right to the final torque. Walk it up in a few steps. This is a general rule for anything like this including multi-port valve assemblies and even lugnuts on a wheel. Hopefully someone else will chime in with specifics.
Best I can do.

Thank you for your reply, Poconos.

I contacted Jandy (Zodiac Pool Systems) and they're sending a replacement o-ring which is the "gasket replacement" you were referring to.

Hopefully that'd stop the leakage.

Good. Probably will fix the problem.
