✔ High-Capacity Flow – Rated at 96 GPM (commercial) / 120 GPM (residential) to handle large pools with ease.
✔ NSF Certified – Meets strict safety and performance standards for residential pool filtration.
✔ Flexible Valve Compatibility – Choose from three Jandy backwash valve options (sold separately, see below).
✔ Versa Plumb Ready – Designed for Jandy equipment pads with universal union connections for easy installation.

Why Choose the Jandy DEV48?

When sand and cartridge filters fall short, DE filtration is the gold standard—and the Jandy DEV48 is built to prove it. The internal grid assembly coats with DE powder to intercept even the finest contaminants, leaving your water genuinely clear rather than just treated. With a 50 PSI max working pressure, durable composite construction, and a standard 6–15 PSI startup range, this filter is designed to run reliably season after season.

Ideal for:
🏊 Large Inground Pools: Sized for pools requiring serious filtration capacity.
🔄 High-Flow Equipment Pads: Pairs cleanly with variable speed pumps running at higher GPM settings.
🔧 Jandy System Builds: Designed to integrate seamlessly with Jandy automation, valves, and plumbing.

Compatible Backwash Valves (Sold Separately):

The DEV48 filter body does not include a valve — choose the option that fits your equipment pad and plumbing preference:

🔵 BWVL-MPV-80 – Jandy Multiport Backwash Valve – 6-position multiport for full control: Filter, Backwash, Rinse, Recirculate, Waste, and Closed.
🔵 BWVL-SLD – Jandy Slide Backwash Valve Kit – Simple 2-position slide valve with pre-plumbed universal union kit included. NSF/ANSI 50 certified.

What's Included & How It Works:

1️⃣ Prime the Grids: After installation, add 5.0 lbs of DE powder through the skimmer with the pump running to coat the internal grid assembly.
2️⃣ Circulate: Water passes through the DE-coated grids, trapping fine particles that bypass other filter types.
3️⃣ Backwash & Recharge: When pressure rises 8–10 PSI above normal startup, backwash the filter and recharge with fresh DE powder.

Includes: Filter tank · Pressure gauge · Air release assembly · Universal unions
⚠️ Backwash valve sold separately. See compatible options above.
