Understanding and maintaining your Airstream holding and dump tanks isn’t as difficult as it may seem at first.

What type of holding tanks does an Airstream have?

Airstream Fresh Water Holding Tank

Your fresh water tank holds potable (safe for drinking) water that you can use when your Airstream isn’t hooked up to city water. If you’re boondocking or stopping overnight without access to a drinking water faucet, you can still use the potable water in your fresh water holding tank – just be sure to remember to turn on the water pump so that you have enough water pressure to get water to the faucets, shower and toilet.
