I’m having a 15x26 ABG installed on Monday. The installer gave me only a few days notice. I called the water delivery company and the soonest they can get here is Thursday. The installer doesn’t think it’s a big deal. Said he’ll add 2-3 inches of water to get the wrinkles out and that should be fine. Do I need to be concerned about the pool being mostly empty for 3 days? It’s a resin pool so I believe the sides are pretty flimsy until it’s full of water.
