I am purchasing a 24' Southport GLX above ground pool. In doing research on these pools, one place said I needed 2 suction floor drains and that they will connect to my sand filter. The other 2 places I shopped at had no idea what I was talking about. Are they trying to rip me off? Are these necessary? Is there alot of maintenance on them? Of course the seller would do the maintenance for me including a hefty monthly fee. I live in a small town and the closest pool seller/supply store is 45 miles away. Do you recommend the floor drains? I'm a total newbie at this and will appreciate any input. Thanks in advance for your help!!!!
