I just purchased a 22x52 Ultra Frame pool, and I am in the planning phase for site prep. I've read the intex links on the sticky of this forum and got me wondering about hard plumbed lines. Can you run those over say 20 feet, If I want my sand and saltwater filter away from the pool, can I run those pipes underground a short distance (20 to 30 feet) ? I havent seen any that have tried that, or at least that I have found. What are your thoughts on this? I do plan to leave it up year round, so I would drain a little water and blow out the lines. I am a little stressed over the site prep work. Appreciate your feedback.
