About This

• WHOLE-HOUSE HIGH-FLOW FILTRATION - This extra-large 20-inch housing holds 4.5" diameter Big Blue cartridges for whole-house, high-flow, and heavy-sediment applications, giving you greater capacity and fewer vessels at your point of entry.
• HEAVY-DUTY CONSTRUCTION - Durable polypropylene sump and HFPP cap thread together with a single large closure and an EPDM O-ring; the large 1-1/2" NPT internal port passes a greater volume through the cap. No pressure-relief button on this model.
• TESTED AND CERTIFIED - This housing is Tested and Certified by NSF International to NSF/ANSI Standard 42 for material and structural integrity; polypropylene housing and cap with an EPDM seal stand up to a broad range of chemicals.
• CARTRIDGE COMPATIBILITY - Accepts 4.5" diameter, 20-inch "Big Blue" cartridges, so you can match the media to your water with large 1-1/2" NPT inlet and outlet connections for high-flow installs.
• PRESSURE AND TEMP RATING - Rated to a maximum 90 psi and 40 to 100 degrees F for 20-inch sumps; protect against freezing to avoid cracking. Cartridge, mounting bracket, and wrench are NOT included and are sold separately.
