Actually it's also pretty handy to know how to do it and to have a spare just in case your pipes and your tush are in danger of freezing. We have temps in the single digits and would have a lot of problems is ours was out for long.

Come to think of it, that check for the difference might be a little too cheap. Send more! (Rolling on the floor laughing.)
