I looked around the forum but didn't find an answer. How often do you replace your main o-ring on your DE filter tank (the o-ring between the two halves)? In my case, it's a Jandy DEL60 which I purchased in 2006. I just opened it up and did my yearly rinse of the grids. I put everything back together and now I have a small leak (a drip every 6-8 seconds). I tried loosening the clamp, repositioning it slightly, and reclamping, but the leak is still there. I put a very thin coating of silicon lube on the o-ring when I put it back together.
Think I should put more lube on the o-ring? How much is too much? Or should I purchase a new o-ring (pricey)?
Last year I had a very small leak also that eventually stopped, but this one is a little more.
