The Jandy BWVL‑NVL‑75 is a 2‑in‑1 side‑mount backwash valve used to direct water flow through a pool filter during normal filtration or when backwashing to waste. Built with Never‑Lube® CPVC thermoplastic, it’s designed for smooth internal flow and avoids a “dead‑head” handle position that can block flow. This valve is made to fit Jandy SFSM Series side‑mount sand and D.E. filters, and it can also be used on Jandy DEV and JS Series filters when installed with the proper unions. It includes pre‑installed filter‑side factory unions plus 2" × 2½" plumbing‑side unions, and it’s rated for up to 50 psi.
