Hayward SPX1099K Skimmer Weir

What This Part Is Used For
The Hayward SPX1099K Skimmer Weir is the swinging skimmer door used in compatible Hayward skimmers. It sits in the skimmer throat and helps hold debris in the skimmer while maintaining surface draw.

Why This Part Matters
Without a working weir, surface skimming is noticeably weaker and debris can wash back into the pool when the pump shuts off. That leads to more vacuuming and less consistent water clarity. Replacing the weir restores proper surface pull and debris retention.

Installation and Fitment Guidance
Remove the old weir and inspect the hinge points before installing the new one. Confirm the door swings freely and does not bind. Confirm by manufacturer part number before ordering.

Common Service Context
Techs usually replace skimmer weirs after winterizing, when plastic becomes brittle, or when the door goes missing. It is commonly diagnosed when debris is not collecting in the basket or when leaves float past the skimmer with the pump running.
