  • One of the most inexpensive ways to prevent your water hose from freezing is probably disconnecting it. Below is a step-by-step process on how to do it.
  • Step 1: Make sure that your RV’s holding tank is filled with water. It’s always a good idea to fill it so that you’ll have enough water supply after disconnecting the hose.
  • Step 2: After the tank is filled, disconnect the hose and put it somewhere away from the cold.
  • Step 3: Use a heating pad and put it over the water pump of your RV. Lay a few towels on top of the pump. The towels act as an insulation device just in case an electric supply is nowhere to be found.
  • Step 4: Put a small lamp on the compartment near the holding tank. The lamp acts as an extra protection to keep your water supply from being frozen.
  • Step 5: Empty the black and gray water tanks. Doing so will offer enough room especially for possible overnight waste within the compartments. After doing such, rinse the water hose to prevent solid waste from getting frozen inside.
  • Step 6: Tightly close the sewer valves. You can now freely use the water on your holding tank for ordinary use. Keep in mind that you have to use it wisely to avoid water shortage.

Tip 2 – Use a Heat Tape

  • Using a heat tape is another way to prevent your RV’s water hose from freezing. Heat tapes work wonders as it produces heat to maintain the right temperature of the water pipes. Wrap the heat tape along the pipe’s length and leave it hanging on the hose’s end. Use an insulation tube to cover the heat tape and make sure that it covers the length of the entire hose. Lastly, secure the insulation by covering it with duct tape. Heat tapes use electricity as a means of heating the pipe, making it stay dry during colder conditions.

Tip 3 – Check if Your Faucet is Running

  • Keeping the installed faucets running is another way to keep the hose from freezing. Constantly moving running water prevents the risk of freezing especially during low temperatures. Before anything else, make sure that the black and gray tanks of your RV are emptied as mentioned on the first tip. Don’t forget to rinse the black tank to prevent leftover solid waste from hardening. Once emptied, keep the gray tank’s valve open. While the black tank’s valve, on the other hand, should be remained close to prevent it from spreading foul odors. Doing so will ensure that there is a constant stream of water without worrying about overflow. Lastly, turn on your kitchen and bathroom faucets. Doing so will make a slow and consistent stream of water. Note: Only do this technique if you’re sure that the pipes will freeze.


  • We hope that these tips helped you out on keeping your RV’s water hose protected from freezing conditions. Being unprepared will result in more hassle later on especially if your water pipes and hose starts to freeze. But with the help of the tips above, you can now bid goodbye to freezing water hoses.
