Turn Off the Water Supply

The first step is to turn off the water supply to your RV. This will prevent new water from entering the water tank as you drain it. To do this, simply close the valve on the hose coming out of your freshwater hose.

Method 1:

  • Locate the fresh water tank drain valve. This is usually located near the bottom of the tank on the outside of the RV.

    If your RV has a shut-off valve for the fresh water line, turn it to the off position.

  • Open the fresh water tank drain valve and allow the water to drain out.
  • Once the water has finished draining, close the valve and reattach any fittings or valves that were removed.
  • If your RV has a water filter, be sure to remove and clean it according to the manufacturer’s instructions before putting it back in place.
  • Once everything is back in place, open the shut-off valve and turn on the fresh water pump.

Method 2:

The first step is to open all the faucets in your RV – this includes the ones in the kitchen, bathroom, and shower. Doing this will help ensure that all the water is drained from the tank. You may also want to turn on the outside shower (if your RV has one) to help speed up the process.

Method 3:

Most RVs have a freshwater tank that holds around 40 gallons of water. When you’re getting ready to leave your campsite, it’s important to drain the tank so the water doesn’t go bad. Here’s how to do it:

  • First, find an empty tote or other container that can hold at least 40 gallons of liquid.
  • Next, locate the fresh water tank on your RV. It’s usually located near the back of the vehicle. Then, with the help of a friend (or two), carefully lift up and remove the cap from the tank. The last step is to slowly pour out all of the water in your tote into the tank until it’s empty.


In conclusion, for the sake of convenience and safety, you should drain the water from your RV before storing it in a garage or outside of your home. This way, you’ll be able to store your RV in the garage or outside of your home without worrying about having to drain the fresh water tank.
