Hi all! Am hoping the tfp forum can help out once again... I have a 36 sf stainless steel DE filter manufactured by Andrews Advantage probably original to the pool build about 21 years ago. No model or serial can be read off the unit. I am in need of a parts list or diagram. Specifically I am trying to determine what part number is the main o ring. Normally my parts match up with the pentair nautilus but not in this case. I have scoured the pool stores to find a match to no avail. Best I can tell the o ring is 3/8" thick x 18 5/16" inside diameter. Does anyone have experience with this filter and can shed any light?
Thanks for reading.
PS_ I did communicate with Pentair who seems to have bought AA and didn't get very far with them
