If you live close enough to your neighbor (most semi-detached homes would fit this description) you can attach your external faucet, from your non functioning household water, to that of your neighbors FUNCTIONING water supply with a common garden hose and By opening the valves on the waterless house, and then the working house. The house with the functioning water supply will supply the non functioning house.

You might call this an Irish solution to an Irish problem. And since we are not currently paying for the water, we aren’t stealing water, just loaning it.
