I noticed today my pool filter dripping water. Not from the bottom plug, or from the center sealing ring, but from underneath. I could not see or feel anything dripping down the sided. I feel with my fingernail what appears to be a crack under neath in the housing. Bummer. Here are some pictures of my current filter. What is it? I do know it is a DE filter. Based on my info in my signature, what model filter would you recommend as a replacement? Are the inlet outlet openings standard in their placement so no additional plumbing work is required? Thank you in advance.
