VIQUA AWP40B-V NSF 42 Certified 3-Piece High-Flow Whole House Pre-Filter Housing with Pressure Relief Valve, Mounting Bracket & Wrench 4.5 x 10 Inch, 1" FNPT, 20 GPM, UV Pre-Filtration

Protect your VIQUA ultraviolet water purification system and improve whole-house water quality with the AWP40B-V NSF 42 Certified 3-Piece High-Flow Pre-Filter Housing. Designed for standard 4.5" x 10" filter cartridges, this manufacturer-certified housing is the recommended pre-filtration solution for VIQUA UV systems removing sediment, chlorine, and particulates before water reaches the UV chamber, ensuring your UV lamp operates at maximum effectiveness for continuous elimination of E. coli, Giardia, Cryptosporidium, and Fecal Coliform throughout your home.Unlike conventional 2-piece housings that require twisting the filter sump against the filter head to compress the O-ring, the AWP40B-V's innovative 3-piece design uses a separate collar that threads onto the filter cap independently. This significantly reduces O-ring wear and stretching, virtually eliminating the risk of leaks at the housing seal and the oversized collar is far easier to grip and remove than traditional housings, making routine filter changes faster, cleaner, and less frustrating. The sump also features a drain port to remove water from the housing before replacing the filter, reducing water spillage during cartridge changes.
