Abstract
A feeder insert apparatus for a tubular water filtration cartridge utilized in household point of use water filtration systems. The feeder insert allows a chemical to be fed into a incoming water supply at a controlled rate by employing a bypass system that allows a predetermined amount of incoming water to flow past the feed chemical without contacting the chemical. The amount of water in the bypass flow can also be manually adjusted through the use of two adjustment mechanisms, an adjustable ring and a rotatable end cap, located on the feeder insert.
