An apparatus for purifying and dispensing water of a quality suitable for human consumption comprises a first reservoir for holding unfiltered water. The water moves by the force of gravity downward through a water filtering and purifying cartridge into a second lower reservoir. An electrically powered hydraulic pump and associated electrical controls and plumbing enable the pump to periodically lift water from the second reservoir to the first reservoir to permit its return through the filter thereby enhancing the purity of the water before it is dispensed. The apparatus may include first, second and third reservoirs wherein the first reservoir is nominally at the same level as the second reservoir with the unfiltered or filtered water being pumped from the first reservoir and passed through the filter into the second reservoir. The associated electrical controls and plumbing enable the pump to periodically move water from the second reservoir to the third reservoir from which the water drains by gravity through the filter into the second reservoir thereby enhancing the purity of the water before it is dispensed.
An apparatus for purifying and dispensing water of a quality suitable for human consumption comprising a water filtering and purifying cartridge, a first reservoir for holding unfiltered or filtered water mounted at least in part above a second lower reservoir for holding water that has first moved from said first reservoir by force of gravity downward thru said filter into said second reservoir, an electrically powered hydraulic pump and associated electrical controls and plumbing to enable said pump to periodically lift water from said second reservoir to said first reservoir to permit its return thru said filter, thereby enhancing the purity of the water before it is dispensed.
