A water filtration unit for use in locations close to a pressurized source of raw water, the unit including a molded plastic base and cover and containing a water filtering module and a raw water tap connection and hose connection between the tap connection and the filtering module and a hose connection from the filtering module and a vessel to be filled with filtered water. The hose connections are secured to the base of the unit and the tap connection rests in a sterilizing tank filled with water in which a sterilizing fluid such as liquid chlorine, (domestic bleach) or the like are included. The tank is filled in the base of the unit to prevent the passage of air to the filtering module, and bacteria contamination of the connections when not in use. The base of the unit has means for ready mounting and the cover is hinge-mounted on the base on one vertical side or the other, depending on the location and access to the unit. The filtering module has an upper capped inlet whereby cleaning and testing compounds can be inserted and a drain from the filtering module which attaches to a tap and includes a needle valve which is adjustable to control the flow through the drain. The flow of filtered water and the flow of water through the drain are approximately the same.
A water filtration apparatus for the separation of impurities from a water supply comprising a casing having a base member and a cover member hinged to said base member, a filtration module and a sterilization tank both mounted on said base member, a quick connector adapted for attachment to a raw water tap, the said connector having a raw water inlet and an outlet drain, and a valve controlling the flow of water through the said drain, a pair of hose connections, one hose connection leading from the raw water inlet of said connector to the top of the said filtration module and the other hose connection leading from the lower portion of the filtration unit to the outlet drain of the said connector, and a purified water hose connection leading from the bottom of the filtration unit, the free end thereof adapted to be directed to a purified water receiving vessel and/or to the said sterilization tank, the said sterilization tank adapted to be filled with filtered water and the said quick connector when not connected to a source of raw water is maintained under filtered water in said sterilization tank to thereby prevent the passage of air through the said hose connections to the said filtration unit and to prevent bacteria contamination.
