I just had a terrible thought and wanted to run it by others who know. I drained my pool in December (eastern Long Island), getting the water level below the returns and just above the pool lights. I blew out all the lines. Plugged the pipes by the pumps, etc. But I did NOT put plugs on the returns (I have 6 of them). I was thinking that is what I did the prior two winters.
Yesterday we had about 3 inches of rain and the water level is now above the returns, so water must have gotten into the lines. I can drain the pool down today while it's relatively warm, but do I have to blow out the return lines again afterward, and then plug the returns at the pool side? I really do not remember plugging these holes in prior years, but I clearly do it on my spa (I plug the jets - 8 of them).
