Hayward filter leaking a little at after cleaning.

[Titan7]

So I cleaned my Hayward cartridge filter a couple weeks ago, put everything back together. Tighten the band to 150inch pounds as recommended my the mfg. started up and noticed at prime I am getting a slight dripping from the filter. Tighten just a hair more it stopped.

Well tonight I added acid so I turned the pump on, well 3 hours later my wife asked why is the pump running on high. For whatever reason one it primed it stared at high speed vs dropping to 30%.

When over to the EQ pad, it’s wet on the pad so I am guessing high speed just mad it leak more.

So tomorrow I will pull the lid off and reset the o ring, it’s only 1 year old.

Do I need to drain the entire filter bottom or can I just depressurize and drain just below the mid section to clean and o ring again. Mgf says no lube, so I will try it again.

Yes. just remove the top part of the filter and reset the oring. Be sure there is no grit or debris on the mating filter halves or on the oring. I am not familiar as to why Hayward would not want to lube an oring seal. I always lubed mine (Pentair model).
You may also want to rotate your top an inch or so from where it is now.
