The Pentek 20" Big Blue Housing (Model #150069) is designed to accept standard 20" x 4.5" Big Blue filter cartridges. This heavy-duty housing accommodates a wide variety of sediment, carbon block, and specialty cartridges in the 20" Big Blue format, giving you flexibility to customize filtration based on your water quality needs—whether you're targeting sediment, chlorine, taste, odor, or other contaminants.

The Pentek 150069 20" Big Blue Housing supports a maximum flow rate of up to 15 GPM (gallons per minute), making it ideal for whole-house filtration applications. It has a maximum operating pressure of 90 psi and a temperature range of 40°F to 100°F (4.4°C to 37.8°C). The 1" FNPT inlet/outlet ports allow for high-volume water delivery with minimal pressure drop across the system.

Yes, the Pentek 150069 housing is tested and certified to NSF/ANSI Standard 42 for material safety and structural integrity. The housing is constructed from high-strength polypropylene with a reinforced cap, ensuring durable performance and safe contact with drinking water. This certification verifies that the housing meets rigorous standards for whole-house point-of-entry filtration applications.

While the Pentek 20" Big Blue Housing itself is a long-lasting, reusable unit, the filter cartridge inside should typically be replaced every 6 to 12 months, depending on the cartridge type and your water usage. Sediment cartridges may need replacement sooner in areas with high sediment levels, while carbon block cartridges often last up to 100,000 gallons. Monitor pressure drop and water quality as indicators that it's time for a cartridge change.

Yes, the Pentek 150069 20" Big Blue Housing comes equipped with a pressure relief button on the cap, which allows you to safely depressurize the system before cartridge changes. It also includes a heavy-duty mounting bracket and housing wrench for easy installation and maintenance. The black cap with blue sump design is engineered for whole-house applications requiring reliable, high-capacity filtration.
