How does this replacement module improve pool and spa filtration?

Installing a fresh 36 sq ft DE module refreshes the media surface area and restores the filter’s ability to trap fine particles. Expect more consistent water clarity, a steadier pressure differential across the filter, and fewer manual backwashes when the element is in good condition.

• Replaces worn or torn soft DE element to recover filtration efficiency
• Maintains designed surface area (36 sq ft) for proper flow and turnover
• Helps lower system pressure spikes and reduces pump strain

Will this module fit my Sta-Rite System 2 modular filter?

The 27002-0036S is made for the Sta-Rite System 2 family that accepts PLDE36-style soft DE modules. Confirm your filter housing model number and element orientation before ordering to ensure compatibility.

• Specifically matches 36 sq ft PLD70/PLDE36 soft-module dimensions
• Designed for direct swap-in installation—no custom trimming required
• Check your housing part number or existing element label for model match

How do I install and maintain the replacement module?

Replacing the module is a straightforward maintenance task: drain and open the filter, remove the old soft element, seat the new module, reassemble the housing, and reconnect plumbing. Follow standard D.E. system procedures—add diatomaceous earth per the manufacturer’s dosing instructions after reassembly.

• Turn off pump and relieve filter pressure before opening
• Inspect manifold and O-rings; replace damaged seals for a tight fit
• Add correct D.E. charge and run for a few minutes, then backwash as normal
