Wintering in an RV

Well today the 23rd January 2021 was our first real taste of actual cold weather in an RV. Today we discovered that our pipes were starting to freeze. We were lucky enough to get away with just the hot water freezing in the kitchen, all others were unaffected  luckily enough We think that the reason for this is that the bathroom water lines are in the service area underneath the floor next to the passthrough. While the water pipes that run from the service area to the kitchen (a total of about 6 feet) are close to the outer skin under the kitchen floor. We have since added a heater to that area and pointed it down the access pass that runs down the middle of the RV towards the back where the fresh water tank is located.

The heater faces an area where electrical cables and water lines make their way to the kitchen, back further towards the rear of the RV where the fresh water tanks are mounted and the 50 AMP socket is mounted. There is a furnace duct that is dedicated to directing warm air to prevent freezing but It needs some help when it's below minus 15 outside.

Well we did have other issues mainly with the sewer hose. It froze solid We figured the issue arose from too many tight bends and as too gradual slope for the flow from the RV to the RV park's drain. Well, we were partially correct with regards to the bends in the pipe. There is a fair distance for the water to travel but at least it's straight now. It's been around - 15 degrees C for the last 48 hours and water seems to be flowing through okay without it slowly freezing up over time.

A gradual slope with minimal sharp bends in the hose is the way to go. It's about 8 feet with a drop in height of about 2 feet from the RV to the park's plumbing. We check it periodically by tapping it to see if ice is building up in the pipe. If so we run a sink full of hot water to melt it.
