Abstract
A filtration system for a pull-down or pull-out faucet includes a multi-channel hose configured to fluidly couple to a spray head, a water filter configured to provide filtered water, and a diverter-equipped T-connector. The T-connector has a first branch configured to receive unfiltered water from a valve cartridge of the faucet, a second branch configured to receive filtered water from the water filter, and a third branch configured to deliver filtered and unfiltered water from the first and second branches to different channels of the multi-channel hose. The spray head also includes an activation switch configured to allow selective output of filtered and unfiltered water from the spray head.
Claims22
A faucet, comprising:
- a spout;
- a spray head;
- a multi-channel hose fluidly coupled to the spray head and disposed in the spout;
- a valve cartridge configured to control flow of unfiltered water;
- a water filter configured to provide filtered water;
- and
- a connector having a first branch configured to receive unfiltered water from the valve cartridge, a second branch configured to receive filtered water from the water filter, and a third branch configured to deliver the filtered and unfiltered water from the first and second branches to different channels of the multi-channel hose;
- wherein the connector comprises a water-controlled diverter.
A filtration system for a pull-down faucet, the faucet having a spout, a spray head, and a valve cartridge configured to control flow of unfiltered water, the system comprising:
- a multi-channel hose configured to fluidly couple to the spray head;
- a water filter configured to provide filtered water;
- and
- a connector having a first branch configured to receive unfiltered water from the valve cartridge, a second branch configured to receive filtered water from the water filter, and a third branch configured to deliver filtered and unfiltered water from the first and second branches to different channels of the multi-channel hose;
- wherein the connector comprises a diverter configured to assume:
- a closed position when the valve cartridge is deactivated such that (i) no unfiltered water enters the first branch from the valve cartridge and (ii) filtered water in the second branch is restricted from passing to the third branch;
- and
- an open position when the valve cartridge is activated such that (i) unfiltered water enters the first branch from the valve cartridge and passes to the third branch and (ii) filtered water in the second branch passes to the third branch.
