Whole House Water Filtration System Overview

The BG-WHLHS75K consists of two 20" Big Blue Housings which are plumbed in series with a wall mounting bracket, pressure gauge, and hardware. The BG-WHLHS75K system consists of a series of large capacity 1" NPT #20 Big Blue housings allowing for greater cartridge capacities and higher flow rates. Each system is also equipped with a pressure relief button to relieve housing pressure during cartridge changes. All filter housings are manufactured of durable polypropylene, have excellent chemical resistance, and are ideal for many residential, commercial, and industrial applications.

Our cost-effective system also reduces the scale in your pipes, appliances, faucets, showerheads, dishes, and laundry, and reduces the usage of soap and household cleaners.

Its exclusive thread design provides superior sealing and greater security against leaks. The replacement filters are compatible with any 4.5" x 20" filter cartridge on the market. It uses the same cartridges as Ametek, American Plumber, Culligan, Flowmatic, Liquatec, Pentek, and Watts, as well as most other brands of housings.
