Pentair Admiral S-20 Skimmer Weir Flap | Admiral S-20 Skimmer | 85001500 Tubing inspect the tank's lower manifoldThe Pentair Admiral S 20 Skimmer Weir Flap (85001500) is the OEM replacement weir flap for the Pentair Admiral S 20 skimmer. The weir flap regulates water flow into the skimmer, allowing surface debris to be drawn in while preventing it from floating back into the pool when the pump cycles off. A damaged or missing weir flap reduces skimming efficiency and allows debris to re enter the pool. Specifications Pentair Part Number 85001500 Part Type Weir
