Yesterday one of my husband's friends came by and winterized our RPOD for us.
My husband is away working. He'll be home briefly on Friday to take said RPOD in for a safety recall to put some lights on it. It'll stay at the shop for a week or two until he can get back in to Red Deer to collect it.
I did what I could to the trailer, but I have neither the physical strength nor the right wrench to open the hot water valve, and neither do I know how to pump anti-freeze through the pipes.
The friend stopped by and took care of it in about 10 minutes. I watched, I fetched, I tried to learn, and I am very grateful.
