ABSTRACT:
The present invention comprises a reverse osmosis water purifying unit in which all the components of the unit are housed in a protective enclosure. In one form the protective enclosure is a water tight protective enclosure which itself is vented to the drain. The only external connections to the enclosure are by means of sealed bulkhead fittings. These fittings are used to connect the water purifying unit to a main water supply line, a dispensing faucet and a drain line. A fourth fitting communicates the inside of the enclosure directly to the drain, or alternatively, the inside of the enclosure is coupled to the drain line internal to the enclosure. The enclosure protects the components of the water purifying system from exposure to outside abuse and damage, and also act to contain and direct and leakage that does occur to prevent any spillage from escaping from the enclosure. Use of a drain line larger than the water supply line allows containment of a leak of any size within a relatively low pressure enclosure. In another form, the protective cause is not sealed, though upon opening, provides easy access to the internal components while providing a water proof service tray to eliminate spillage of water released upon disassembly of the water purifier for servicing.
