20 Inch Big Blue filter housing for Whole house / Jumbo filters with pressure relief is suitable for high-flow and heavy sediment applications. The blue filter housing is made of reinforced polypropylene for strength and resistance to chemicals, and the black cap is made of high-flow polypropylene for stiffness. The black cap has 1” female National Pipe Thread Taper threaded input and output connections and a rubber O-ring to ensure a watertight seal. A pressure relief button on the inlet side of the cap releases pressure in the housing for changing filter cartridges. The housing can be used with a 20” x 4-1/2” filter cartridge (sold separately). It has an initial pressure drop of 1 pound per square inch (psi) at a flow rate of 15 gallons per minute (gpm), a maximum operating pressure of 90 psi, and a maximum operating temperature of 100 degrees F (37.8 degrees C). This filter housing meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is for use in various high-flow applications, including residential drinking water filtration, food service, and irrigation, among others.
