How to keep your tanks & water lines from freezing!

When it comes to freezing up your RV, the first rule is: Don’t let it happen. Freezing water in a line is expanding water, and it will likely cause damage. Let’s look outside first. When nighttime lows drop below the freeze point, most RVers abandon any idea of hooking up a hose to their “city water” inlet. Fill the rig’s fresh water holding tank and let your RV’s water pump keep water at the ready. Of course, it’s critical that you keep the RV warm — keep the heat on to keep the rig’s water lines from freezing up.

Here are our top RV freeze protocols to keep freezing at bay:

  1. Fill all holding tanks and then drain tanks and close the valves, check water level in batteries, fill as necessary

  2. Fill freshwater tank, test pump operation then turn it off.

  3. Fill propane (LP) tanks

  4. NOTE: 2-40 lbs. LP bottles will last 6-7 days at 20* ambient, 65* on furnace

  5. As freezing temps start to drop at night, take a shower, disconnect the “city water hose”, drain the black and grey tanks again and close the drain valves. Use the on-board water pump as needed. Conserve, conserve, conserve!

  6. Turn LP side of the water heater “on” in case electricity goes out. (yes, both electric and LP can be on at the same time)

  7. Hunker down until it warms up.

  8. If you have to leave the RV for shelter you can set the furnace to 45*F so that LP will last longer, and this should prevent any freeze damage inside the RV.
