Hayward W490R Automatic Skimmer Vacuum Plate

What This Part Is Used For
The Hayward W490R is an automatic skimmer vacuum plate used to connect a vacuum hose to a pool skimmer for suction cleaning. It sits at the skimmer opening and provides a dedicated suction path to the vacuum line. This lets you vacuum the pool using the skimmer as the suction source.

Why This Part Matters
Without the correct vac plate, the hose connection may be loose and pull air, causing poor suction and loss of prime. A proper plate improves vacuum performance and helps protect the skimmer setup during cleaning. It also keeps the vacuum connection stable so you are not fighting the hose every few minutes. Correct fitment matters because skimmer throats and baskets vary by model.
