I have a Jandy DE filter (DEL60) and I'm pretty new to pool care. The previous owner told me to take apart the filter and clean the grids twice a year. So last year I took it apart and when putting it back together I realized the O-ring was seriously stretched. (Filter probably about 10 years old) So when I put it back to together the oring seal leaked pretty bad. I purchased a new one, and it was snug, and after lubing it up with silicone, the leaks were gone.
However, this year I go to clean it again and now putting it back together the leaks are back! The o-ring is snug as well, so it hasn't stretched at all. The guy at the pool store told me to beat the container ring firmly with a mallet as I tightened it down. I did this but still get some leaks when the pump runs. I'm on my 3rd try, so I thought Id ask for help before I take it down again.
Couple of questions for all you pros.
1. Are there any tricks to getting a good tight seal? I don't want to over-tighten the ring... Currently I coat the ring in a bit a silicone, place the ring on the bottom half, place the top half of the filter on carefully trying to seat it evenly. Then slowly tighten the ring as i try to make sure its evenly clamping down.
2.How much silicone should i be putting on this ring? Whats the method you guys use to apply?
3.Can I use just straight silicone from a caulking tube from home depot? The silicone from the pool store seems to be very expensive for the amount you get....
