My husband and I have an intex pool from last year. We already have it opened and ready to go for this season. We want to install a through wall skimmer in the pool but the question we have is that the pool has two inlets that connect to the pump that clean the pool. We have a sand pump connected. First off we aren't sure what would be the best way to plug both of those holes once we have the new skimmer in place. Both holes are far down on the pool and are both next to legs of the pool. So we can't use either for the wall skimmer. I hope this makes sense.
