Pentair Vacuum Plate Adapter | Admiral S15 & S20 Skimmer | 85001900

Description

The Pentair Vacuum Plate Adapter (85001900) is the OEM replacement adapter for the Admiral S15 and S20 skimmer lines, enabling vacuum head attachment directly through the skimmer for manual pool vacuuming.

When vacuuming your pool through the skimmer, the vacuum plate adapter seals over the skimmer basket opening and directs suction to the vacuum hose connection. Without a properly fitting adapter, suction is lost and effective vacuuming is not possible. This is the correct OEM replacement when your existing adapter is cracked, warped, or missing.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Pro Tip

The vacuum plate adapter must seat flush and form a complete seal over the skimmer basket opening to maintain suction during vacuuming. Before ordering, confirm your skimmer model number — it is typically molded into the skimmer body or printed on the underside of the lid. The S15 and S20 are distinct skimmer lines; verify your model against the Fits Into table above to ensure this adapter is correct for your installation.
