Skimmer Flap

[jjdurrant]

I need to replace the plastic flap that sits in my skimmer.. any idea what size that is?

Varies...best bet would be to take the old weir (flap) it out and measure the old one...or if it's missing, just measure your skimmer opening and deduct 1/4 inch on all 4 sides.

There should be a part number on the skimmer weir door (the flap), and also on the skimmer lid. If there's no number on the weir, the lid number will identify which manufacture and model weir you need.
There are also generic weir doors, which are sized as dmanb2b mentioned above.
