I have a Jacuzzi j-c150 cartridge filter. It has begun leaking around the top. I tried replacing the o-ring. No help. What can I try to resolve this issue?
You can try putting more lubricant on the o-ring. It sounds simple but it frequently works. We recommend a silicone or teflon lubricant.
If that doesn’t work, the next step would be replacing the complete lid assembly.
