1. They ran the hot and cold facet until AF ran through (toilet also), but they did not add any additional straight antifreeze in the sink traps or toilet. Maybe enough of the AF went down the drains to protect the traps?
2. At the end, they drained the grey and black water tanks. Should there be some AF in these tanks over winter?
The manual says to put 1 gallon of AF down each sink drain and toilet to protect the traps and the black and grey water tanks. They did not do this step.
You had a better experience than me. My dealer would not let me watch what they do for their $90 winterization service. They wanted another $80 to dump the tanks; I refused that expense. Did it myself yhe next day.
I stopped at a store a few miles away and noticed water pouring out of the RV. They told me later that they leave the fresh water drain open, a heads up would have been appreciated.
I couldn't find the cap and the service writer didnt know what happened to it or if it even has a cap. It might just have a valve.
