Yo! I have a steady leak through my backwash valve. It leaks more when running but dribbles while off. I’ve taken the valve out and re-lubed the o-rings which seemed to help for a couple days. This has been ongoing for a while and I’m wondering what I’m missing? Any help is appreciated.

Might just be time for a rebuilt kit. New seals and such. Or consider replacing with a multiport valve to give you more options (i.e. recirculate, waste, etc).

What Pat said 
Needs a rebuild kit. The orings are probably compressed and deformed with age. Lube won’t help.

Thanks guys... ordered a new rebuild kit.... Amazon told me I bought the same kit in 2019.

Do you backwash a lot? My filter is oversized for my pool volume so I almost never backwash, just clean out the filter once per year. If you don’t already do so, I suggest you clean out the filter yearly and you open up and clean out that valve as well as inspect and lube the orings generously. The interior surfaces can get DE on them and that can be abrasive to the o-rings.
