winterizing - i'm late !

If you have done it yet, get it winterized on Sunday. Check the clear plastic water strainer on the input side of the pump, its quite vulnerable.
I know -7C is not cold for some people in Ontario, saw 3 people in shorts and sweat shirts at Costco (Barrie), including one in shorts and shirt pumping gas, standing in 6" of snow.
Water does freeze at 0C and with the forecast its not likely to melt for a while, only get worse. You may have to figure a way to get heat to the pump etc, to get the job done, or expect big repairs next spring.

I would turn the heater on and try to winterize after it thawed out. Did you pull the plug on the water heater and drain?

A neighbor down the street put off winterizing a motorhome, destroyed the water lines, water heater, toilet, faucets, outside shower, p-traps and the drain valves on the gray and black tank.

My thoughts exactly. We use an electric space heater during winter to keep the rig above freezing.

Basically i'm worried about running the pump. Likely i'll wait till a warmer weather spell develops as i'm pretty sure i drained things well. Ha, unless not knowing gets the better of me.

I'll update when i have a conclusion. Thanks All.

Until you are sure it is thawed, running the pump would not be a good idea. Removing a "P" trap (kitchen or bath sink), will tell you right away, if you have frozen pipes. If you have ice in the traps, you have it everywhere.

If your lines are frozen, running the furnace, with cabinet doors open, could take a couple days to thaw. Shore power and electric heaters, blowing into areas with plumbing lines, along with furnace heat, will speed that up. No shore power, maybe, you could bring a generator.

Other items that may help (depending on access to shore power):

Hair dryers
Disposable hand warmers (wrappped around the pump or "P" traps / outside shower)
Electric heat pads

Fastest thaw would be in a heated building.

19F for a few days...ouch, hard extended freeze.
Hope for the best, but not good.
Get over there and get it done...and again, hope for the best.

I would open the low point drain on the Fresh water tank and hope for the best with your water lines since I expect all liquid inside the lines have frozen up with hopefully no damage. The next warm day you have I would take a day off and blow out all the lines and get RV-antifreeze onboard. Hope your water lines were nice to you!!

If that was a hard freeze (below freezing both day and night) for more than a day, I'd be worried too.
