Swimline HydroTools Olympic Skimmer Weir Door, 8926

This is the HydroTools 8926, the replacement weir style door flap for HydroTools and Olympic skimmers. It measures 5-3/4 inches wide by 4-7/8 inches tall.

Why the weir matters

The weir door is the piece that makes a skimmer skim. It floats up against the water line so the pump pulls a thin, fast sheet of surface water over it, which is what carries leaves and film into the basket. When the pump shuts off, the door falls closed and traps what you just collected. Without it, debris drifts straight back out into the pool overnight.

Before you order

Weir doors are not interchangeable between skimmer brands, so measure the flap you are taking out against 5-3/4 inches wide by 4-7/8 inches tall. If those match, this one drops in by hand with no tools.
