About This Item
The Pentair Spring Check Valve (27001-0130S) is the OEM replacement spring check valve for the Sta-Rite System:2 Modular Media (PLM Series) cartridge filters and System:2 Modular D.E. (PLD Series) filters.
IMPORTANT: OPTIONAL EQUIPMENT
This spring check valve is listed as optional equipment for the PLM and PLD filter systems — it is not included as standard. Verify whether your filter configuration uses or requires a check valve before ordering.
IMPORTANT: PLD SERIES — MODEL YEAR APPLIES
For PLD series filter systems, this check valve applies to 2009 and later models. Confirm your filter's manufacture date or model revision before ordering if you have a PLD series unit.
The spring check valve prevents backflow through the filter's internal plumbing, maintaining directional flow and system pressure integrity. When the valve fails or becomes worn, backflow can compromise filter performance and reduce circulation efficiency.

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.
Poolaroo Pro Tip
The compatibility data confirms this check valve fits all PLM series models — so if you're unsure of your exact PLM model number, you're covered across the full PLM range. For PLD series filters, check the label on your filter tank or the original installation manual to confirm your unit is a 2009 or later build before ordering. When replacing the check valve, inspect the valve seat and surrounding housing for wear or debris that may have contributed to the original failure — a clean seating surface ensures the new valve seats correctly and holds backflow pressure as intended.
