Sounds like a plan. Thanks, again, Richard. When my husband gets back in town this weekend, that will be on the top of my list. Any idea what this is? There is one below each skimmer opening. I’m thinking it’s one of those skimmer leveler devices? My guess is that the second open hole in the bottom of the skimmer goes to that and maybe the main drain isn’t plumbed to the skimmer at all. UGH. Why didn’t I request the pool build paperwork when we bought this house?
