Well, the pool renovation job is moving along but I need some advice. We'll be coring 3 new holes in the pool, two for returns and one drain. Will a 2 1/2" core be large enough to pass a 2" pipe? How about a 2" core for a 1 1/2" pipe? I know that seems like "Who's buried in Grant's tomb?" but I'd rather ask a dumb question than screw up the job.
Next question: We're setting new skimmers (level, which they weren't before) and were wondering, is there an ideal distance for the waterline to be from the bottom of the coping? We'll install 6" tiles so does that automatically make the answer 3" or can that vary? Thanks for your help!
