Why Your Skimmer Weir Door Matters

The weir flap is the small hinged door inside your pool skimmer basket opening. It serves a critical function: it allows surface water and floating debris to flow into the skimmer efficiently, then closes when the pump is off to prevent debris from floating back into the pool. A cracked or missing weir door noticeably reduces your skimmer's effectiveness — replacing it is one of the easiest and most affordable ways to restore peak pool performance.
