Waterway Crystal Water 36 SqFt D.E. Filter 72 gpm

The Waterway Crystal Water 36 sq ft DE Filter is a high-performance diatomaceous earth (DE) filter engineered for sparkling pool water and efficient flow. With a reinforced polypropylene tank and 2½″ internal plumbing, it minimizes hydraulic restrictions and delivers smooth, quiet operation. Its design supports long DE cycles and easy maintenance.

Features

• 2½″ Internal Piping — reduces flow restrictions and lowers system noise.

• Fiberglass-Reinforced Polypropylene Body — for strength and chemical resistance.

• Curved Vertical DE Grids — maximize surface area for efficient filtration.

• “Start / Service” Dial on Stainless Steel Pressure Gauge — helps you know when to clean.

• Heavy-Duty Manual Air Relief Valve — for safe purging of trapped air.

• 1½″ Bottom Clean-Out Port — for easy draining of DE and water.

• 3-Segment Clamp Ring — secure lid for maintenance access.

• Compatible with 2½″ or 2″ Valves — gives flexibility for plumbing options.

• NSF Certified — meets safety & performance standards.

Benefits

• High Filtration Efficiency: Can trap very fine particles (DE filtration) for clearer water.

• Optimized Flow: Large internal piping reduces resistance, improving pump efficiency.

• Durable Construction: Tough tank material holds up well against pool chemistry.

• Long DE Cycles: The large surface area of the grids means you don’t need to recharge DE often.

• Easy Maintenance: Access via clamp, drain port, and air valve make it user-friendly.
