First off I wanted to thank everyone here for posting such great and detailed information, I went from a green swamp to nice and clean in less than a week!!
I am a first time pool owner who purchased the house last Aug. The pool had some workarounds done by ther previous owner: both the suction and return lines were pvc pipes going from the equipment pad, across the deck, over the coping, dropping a foot into the pool.
I had some work done by a pool builder who repaired one of the return lines, closed off the second one and installed a new skimmer and plumbing to the pump. He also informed me the drain is not working. I had him do just enough to make it functional without spending too much money (house needed work too).
I was thinking of getting a new pump and cleaning up the plumbing around it. I've been reading up on pumps (2 speed vs VS.) but was wondering what you guys think of the filter I have and how having only a single (1.5") return line come into play when choosing the pump. Eventually it'll need replastering and I'll look into repairing the drain and adding more return lines then.
