Big Boy units use standard-sized high flow vessels (known in the industry as 20" Big Blue) that are capable of treating up to 15 gallons per minute.  These units are built with full-flow double-sized “big blue” vessels and accept jumbo-sized 4.5" X 20" cartridge.  Big Boy units come with 1.5" ports (you can “bush” down to any smaller size if your pipe size is smaller). These are tough, heavy duty units built to deliver very clean, bacteria-free water.
