Abstract
An apparatus for filtering water has an interface and a filtration/purification canister removably mountable onto the interface. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. The interface provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus from backflowing into the filtration/purification canister and contaminating the portion of the filtration/purification canister downstream of the filter/conditioning/purifying medium held within the filtration/purification canister and thereby causing water exiting the outlet port of the filtration/purification canister to be contaminated.
