This week’s low temperatures in San Antonio averaged 28 degrees, with daytime highs in the 30s. Unless you prepare for them, these temperatures can wreak havoc on RV water systems. With temperatures in the 20s, water hoses can freeze, tanks can freeze, and water lines to disastrous effect.

What should you do to prevent RV issues from frozen pipes and possibly frozen tanks?

First, empty your black and gray water tanks before the cold weather and unhook your sewer hose. Store your sewer hose.

Second, fill your fresh water tank and unhook all water hoses.

The only connection is to electricity when temperatures stay below freezing for extended periods during the day.

Bertha looks like this when the weather is going to be below freezing because, buttoned-up, she can retain all the heat generated by the furnace, heat pump, or space heater. The furnace ducting is run to provide heat to the wet bay.

Notice the silver ducting in the wet bay. This allows for safe operation and helps prevent frozen tanks and pipes.

The bottom line is that it only takes a minute to protect you and your RV from costly repairs and other issues when the temperatures drop and stay below freezing. Thankfully, I learned this lesson by reading and YouTube instead of by living it.
