Abstract
The present invention relates to a residential home water filter system and method. The water filter system comprises a filter stage, a water purification stage, a water storage stage, and a back-up water softening stage, to deliver filtered and purified water to consumers when needed. Water from a pressurized water source first flows through filter 16 and then to a first junction 18 to a reverse osmosis system 22 when a pump 24 is activated or to an ion exchange water softener 20 when the pump 24 is deactivated. The filtered and purified water is then stored in tank 26.
Claims5
A system for supplying purified water to a building comprising:
- a pressurized water source;
- a first junction to supply water from the pressurized water source alternately to a first water line leading to a reverse osmosis apparatus and to a second water line leading to an ion exchange water softener;
- at least one filter between the pressurized water source and the first junction;
- a pressurized tank configured to receive water alternately from the ion exchange water softener and the reverse osmosis apparatus via a second junction, wherein the reverse osmosis apparatus supplies water to the pressurized tank through the second junction via a third water line, and wherein the ion exchange water softener supplies water to the pressurized tank through the second junction via a fourth water line,
- wherein the third water line leading to the second junction from the reverse osmosis apparatus comprises a pump for increasing the pressure of the water through the first water line,
- wherein the water is supplied through the reverse osmosis apparatus when the pump is activated to fill the pressurized tank, and further wherein the water is supplied through the ion exchange water softener to fill the pressurized tank when the pump is deactivated,
- wherein the pump is deactivated when the water in the pressurized tank supplied by the reverse osmosis apparatus is depleted to a predetermined amount thereby filling the pressurized tank with water from the ion exchange water softener.

A method of distributing purified water to a building comprising the steps of:
- providing a pressurized water source;
- providing a system for providing purified water to the building comprising a first junction to supply water from the pressurized water source alternately to a first water line leading to a reverse osmosis apparatus and to a second water line leading to an ion exchange water softener, at least one filter between the pressurized water source and the first junction, a pressurized tank configured to receive water alternately from the ion exchange water softener and the reverse osmosis apparatus via a second junction, wherein the reverse osmosis apparatus supplies water to the pressurized tank through the second junction via a third water line, and wherein the ion exchange water softener supplies water to the pressurized tank through the second junction via a fourth water line, wherein the second line leading to the reverse osmosis apparatus comprises a pump for increasing the pressure of the water in the first water line, wherein the water is supplied through the reverse osmosis apparatus when the pump is activated to fill the pressurized tank, and further wherein the water is supplied through the ion exchange water softener to the pressurized tank when the pump is deactivated;
- supplying water from the pressurized water source to the building, wherein the water is purified through the reverse osmosis apparatus but not softened within the ion exchange water softener or softened through the ion exchange water softener but not purified through the reverse osmosis apparatus;
- activating the pump to supply water from the reverse osmosis apparatus to the pressurized tank;
- drawing water from the pressurized tank to distribute around the building;
- deactivating the pump when the water in the pressurized tank supplied by the reverse osmosis apparatus is depleted to a predetermined amount;
- and
- filling the pressurized tank with water from the ion exchange water softener.
