Product details

Pentair 85001500 is the replacement weir door for the Admiral S20 skimmer. It is the hinged flap that sits in the skimmer throat.

Why the weir matters

The weir floats up and down with the water level and holds a thin sheet of water spilling over its top edge. That is what gives a skimmer its grip on the surface, and it is also what stops leaves and bugs washing straight back into the pool when the pump shuts off. A weir that is cracked, warped or missing leaves a skimmer barely skimming.

Sizing

Two dimensions are on record for this part. The listing gives it as 8-1/16 inches, and the specification sheet gives 8 inches wide by 5 inches high. Both figures are carried here. Measure the old weir first if your Admiral skimmer is an older build or has been repaired with mixed parts.
