Abstract
An apparatus for filtering and/or purifying water flowing through a water distribution system has a water filtration/purification cartridge mounted inside a housing. The apparatus provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus backflowing into contact with the outlet side of the filtering and/or purifying matrix of the cartridge to prevent possible contamination of the outlet side of the matrix from such backflow and thereby cause water exiting the outlet port apparatus to be contaminated.
