First time posting but a regular reader. I searched the forums and I couldn't find any information that would help me with my issue. Sorry of this is a repeat.
I am having issues with blown filter cartridges in my Pentair DE Quad 100 Filters. The pool is new this spring and opened in May.
Pool Characteristics:
1) 50,000+ gallons
2) Two Pentair DE Quad 100 Filters (One filter is assigned to the 12 foot deep end. The other filter is assigned to the 3 skimmers)
3) Three Pentair 3HP Intelliflo VSP pump. Each filter has its own pump. The other pump feeds rock slide and waterfall.
4) Return line is 2" and the flow can be split between the 6 wall returns and/or 2 shelf bubblers. (Both filters join into the same return 2' return line.
5) Pentair Hybrid heater
6) SWC generator
7) Sun shelf with 2 bubblers
8) Waterslide and slide
9) Acid dispenser
History:
At the beginning of July we came home to the entire pool floor coated in DE powder. The filter was opened and it was found that all 8 filters had failed, rupturing through the blue rubber end cap. Spoke with my pool maintenance company and no reason was identified as the cause. New filters were placed and we moved on hoping it was a weird one time event. Recently larger white flakes started to appear on the pool floor at the return ports. Some return ports have heaver debris deposits than others. My pools service said it was "pool dandruff" coming from the SWC generator and recommended an additive to help control scaling. Today the filter was opened and we found that 5 of the 8 o filters had ruptured. This time the pool service thinks it may be the high-flow backwash valve causing the problem. I am at a loss as to the reason of continued filter cartridge failure. Any help would be appreciated.
Thanks
