First, I am new here and very very new to pool care. Great forum. Already learned a lot just reading some posts!!
My problem: We have a fiberglass inground pool that was installed last fall. It is now up and running for the summer. We have been working on getting it clean and ready. Today we noticed while vacuuming it that dirty water was coming back out of the return jets. We shut the system down and checked the filter (Pentair Clean and Clear). We noticed that the rubber end cap on the filter cartridge is cracked and the "bands" around the pleats are broken. Could this be causing dirty water to get back in the pool? I read that this could be caused from the filter being "plumbed backward". I also read that the filter cartridge has an average life of 3 years. I just don't see how this would happen after the pumps only been running for about 2 months. (The pool was winterized right after installation)
Please forgive my lack of pool terminology and knowledge. We have not received any support from the pool installers and it's becoming REALLY FRUSTRATING!
