I just had the floor of my IG gunite pool painted with an epoxy coat and it is currently in the 7-day curing process. I want to take advantage of the fact that it is empty and blow out and seal all of the pipes before I refill the pool. The return lines and skimmer lines are not really any different from a normal closing after draining below them. But I'm wondering about the main drain line.
Is there any reason not to blow out the main drain line and put a rubber plug in it before refilling (other than the hassle of diving down and removing it in the spring)? The deep end is 8.5 feet.
