We are currently have a spirited discussion in our area about whether to run our pumps wet or dry in sub zero temps. Am wondering what other departments do and the rationale behind it. Anyone have and good facts from manufactuers on this topic.

Use the little search button on the left. There are probably 5+ threads on this that should give you lots of back and forth discussion with no final answer. :D
As a guy that lives in sub zero temps, we drain our pumps and lines from mid october to march. Simple reason being if you are an extended run the pump (especially on older trucks - newer models have heaters) will freeze and blow the packing out or crack your pump. Showing up at a rural fire with a frozen pump is counter productive - unless you park close to the fire! It has happened several times in the surrounding area - and it is costly to fix. By the time your pump is primed and ready to go the hose should pe pulled and ready. Really what does priming add to your operation 20 seconds?? Better to take the time than put a piece of equipment in the shop!
