After backflushing my DE filter and recharging, DE shoots into the pool slowly over the next several weeks.
I had the filter professionally disassembled/inspected -- no problems found. I also replaced the multiport valve. The problem continues.
My backyard is sloped and the equipment sits about 4-5 feet below water level, causing increased water pressure on the multiport that perhaps affects its seals. Water seems to seep slowly through the multiport even when it is closed (multiport is new, and spider gasket looks fine). I don't know if an imperfect multiport seal would cause DE to leak into the pool, or if perhaps the DE filter itself has invisible defects. The DE filter is unknown age, probably 10+ years (?). My pool guy is stumped.
I was thinking about scrapping the DE filter and buying a new cartridge filter, until I realized how much small debris (pollen, seeds, etc) falls into the pool in spring & fall. I must backflush 2-4 times each spring and fall, and I don't want to disassemble a cartridge filter that often. Backflushing the DE is way faster/easier than filter disassembly.
Any thoughts about either (a) solving the DE leak, or (b) using a cartridge filter in a high-pollen area (two large trees nearly overhanging pool, which I will not cut)?
