Friend of mine, is acting as caretaker for a family member's house. The power got shut off, and the house is cold inside. Down to 37, last he checked. Four burneers on the stove for an hour raises the temp two entire degrees.
Last night, we put RV antifreeze in the drain traps. Toilets, sinks, showers. We considered the dishwasher. But that hadn't run in six month or so, and probably the trap dried out. Washing machine is in the cellar, and should stay warmer.
For $3.97 that might be a lot cheaper than replacing a bunch of broken pipes. I got to thinking. On the way home, I bought myself a jug of antifreeze. Might never need it. But it might be cheaper than replacing a bunch of pipes and such if I need it here, or for a friend some day.
