Off-Grid: Patio Sink Install with Gravity fed Garden Hose Adapters

I've recently installed an outdoor sink, faucet, and drain for the patio. It's convenient to have easy access to outside water for hand washing and other uses. The faucet's hot and cold water lines are supplied with gravity fed collected rain water from the cabin's roof. A couple adapters were needed to connect each water line.

Faucet Water Supply Hose Adaptation

In the picture above you can see the braided hot and cold water supply hoses from the faucet. The female threaded connectors are 3/8". In the picture below you can see the 3/8" male to 1/2" IPS male adapters, and the 1/2" IPS female to 3/4" female garden hose adapters that I purchased from the hardware store. Thread Seal Tape was used to wrap the male connection threads a few times to act as a gasket to ensure a water tight connection.

In the pictures below you can see how the adapters have been connected and tightened.

Next the adapters are attached and tightened onto the faucet water supply hoses.

Hot and Cold Water Supply Connected

In the picture below you can see the faucet's cold water supply hose connected to the hose that is gravity fed from the cabin's south side of the roof rain collection barrels. The faucet's hot water supply is connected to the hot water from the rocket stove boiler that also feeds the outdoor hot shower. Both gravity fed water supply hose lines are connected to the faucet hoses with a standard male 3/4" threaded garden hose connector. You can see from the faucet test that the gravity fed water is providing a conservative flow. It's just enough for me to wash up with without draining the rain barrels too quickly.

Sink Drain Installed

In the picture below you can see how I drilled, carved, and filed a perfectly sized hole for the black drain hose. It happened to be an almost perfect fit for the sink drain hole.

I filled in the space between the drain hose and the porclean sink drain with hot glue. I will eventually purchase a proper sink drain kit.

Sink Drains to Wild Strawberry Garden

We take care not to put anything in the sink that is not safe for plants or animals. In the picture below you can see the drain hose from the sink where it empties into the wild strawberry garden.

I'm looking forward to easily washing my hands outside after working in the garden.
