I am putting water in my owner-built pool for the first time. However, the skimmers are still plugged with approx 1 9/32" square headed plugs and I can't get them out. I tried the basin wrench sold at ACE hardware, but it was too small and broke quickly. Home Depot did not have anything to help. Does anyone know a place to get a T-shaped basin wrench big enough to get these out? I've tried tracking down the plumber, but he's away for the Holiday weekend.
