Thanks for responding. I have had very little luck getting information. Dig plan was aquired and I now have someone to dig the hole for me. I have been given quotes up to $10,500 even though I already have the pool and when I asked for a detailed breakdown of the quote I never heard from them again. When I questioned one contractor as to why we would need 300 feet of 1 1/2 pipe on a 24 ft. pool, he never returned my call. The pool is still sitting in my backyard and a brand new skimmer is in my living room. I found a 3 month old filter and sand pump for $250 that I'm told is the right size for my pool. I have done some research and have read about installing sump pump piping under the pool. Some say it's a waste of money, others have told me horror stories of a hard rain during installation causing the pool to rise out of the ground and having to remove it and start over. Your thoughts? thanks
