Peculiar MO (Sunny Low 33 High 55)
Another winterizing lesson learned - this time on a frozen sewer hose. In addition to the tall water faucet at this park the sewer location is just barely downhill from our drain. Another complicating factor is that we are a greater distance from drain to sewer that would serve us best in the winter. We had to use two 10' sections of sewer hose. By taking off the clear adapter and the twist on waste valve blade assembly we got the drain as high as we could. Then by propping up the sewer hose support system with cement blocks and wood we were able to get the best drainage we could for this setup.
Turns out it was not good enough, there was still more than usual water left in the sewer hose. With those cold nights around 20 it froze. Luckily we did not have to dump at that time and could wait for it to thaw out. Bob researched what to do in this situation and found a great article on rv-forum on winter camping. The solution was to buy heat tape and wrap the sewer hose and then wrap with a water heater blanket cut to fit. The water heater blanket was selected since it had a vinyl backing which should prevent moisture problems. We just got some rain and the job held up real well.
Here is the entire length of the finished assembly (click on the link above for a better description and an in-progress version):
Here is a smaller view to show the finished assembly with lots of duct tape.
Our new winter checklist:
- sensor for heated water hose out in the elements; CHECK
- water faucet wrapped with heat tape and covered with pipe insulation and then an inverted trash can sprayed with foam insulation; CHECK
- sewer hose wrapped with heat tape and then wrapped with insulation; CHECK
We are hoping to NEVER need this checklist again! We are also hoping that this concludes all of our winterizing lessons learned. If it gets this cold after this winter wherever we are we are heading SOUTH!!
Till next time,
Bob and Jo
