AstralPool - Skimmer Weir Flap (Replacement) - 4402010192

AstralPool – Skimmer Weir Flap (Replacement)

This is a genuine AstralPool replacement weir flap for AstralPool in-wall pool skimmers. The weir flap sits at the skimmer mouth, just below the water surface, and acts as a hinged door that allows surface debris — leaves, insects, and other floating matter — to enter the skimmer basket while preventing it from washing back into the pool when the pump is off. Keeping this part in good condition is essential for efficient surface skimming and overall water quality.

How it works

When the pool pump is running, water flow pushes the flap open, drawing surface debris into the skimmer housing. When the pump stops, the flap closes, trapping collected debris in the basket and maintaining the water level at the skimmer mouth. Over time, constant movement and UV exposure can cause the original flap to warp, crack, or lose its pivot action — making a like-for-like genuine replacement the safest choice.

Compatibility

This flap is a genuine OEM spare part referenced in Fluidra/AstralPool exploded views 74457, 74458, 74459, 74460, 74461, 74462, 74463, and 74464, covering multiple AstralPool skimmer models across the 15 L and 17.5 L ranges for concrete, liner, and polyester pools. Always cross-reference your skimmer’s exploded view diagram or part number before ordering to confirm fitment.

Why genuine matters

AstralPool skimmer components are made from UV-treated ABS plastic engineered to withstand continuous pool chemical and sunlight exposure. A genuine OEM flap ensures the correct pivot geometry and sealing profile for your specific skimmer body, avoiding the poor fit and premature failure that can come with generic alternatives.
