Well, it was -8 the other night in the Black Hills of SD. I saw the forecast so I hung a trouble light 100 watt bulb in front of the water manifold thinking that would do it, wrong! The next morning no water so I resorted to a small electric heater and in a couple of hours still no water. I then pulled off the filter housing thinking if that's froze I'm screwed. It wasn't? It was a little low in water so I filled it back up to the top and away she went, water! Ive had a few filters on cars that you had to prime or it wouldn't prime its self. Oh well, no damage so we were happy!
