2 Pee, Or Not 2 Pee.

That is the question.

One of friday's jobs involved a flooded shop due to a burst pipe.  On further investigation, the toilet upstairs was seen to be frozen solid... Down to the very bottom. The water in the tank was also as liquid as a brick. Surprisingly, the ice had not split the porcelain.

There's a little wall mounted heater, low powered, about 100 watts, or less, in the room. But it was not turned on. The tenant was surprised that the pipes had frozen. They're on the uninsulated outside wall, and the night-time temperatures have been hitting -10C or thereabouts for the last couple of weeks, daytimes have rarely climbed above freezing.
