How long will 40 gallons of water last in an RV?

How long will 40 gallons of water last in an RV?
From my personal experience, the length of time that 40 gallons of water will last in an RV can vary depending on a few factors. Here are some things to consider:

  • Water consumption: If you are using your RV’s shower, sink, and toilet frequently, you will go through water more quickly than if you are conserving it.
  • Number of people: Obviously, the more people using the water systems in your RV, the faster you will go through your water supply.
  • Toilet paper usage: Some RVers recommend using special RV toilet paper that breaks down more easily in the tank, but regardless of what kind of toilet paper you use, using too much can fill up your black tank more quickly.
  • Tank capacity: As mentioned in the input, it’s a good idea to empty your black tank when it is at least two-thirds or three-quarters full. This will help prevent any overflow or unpleasant odors.

In my experience, with two people using the water systems in our RV moderately, 40 gallons of water can last us about 5-7 days. However, if we are more conservative with our water usage, we can stretch it out to 10 days or more. It really depends on your individual habits and needs.

Overall, it’s important to be mindful of your water usage and tank capacity when RVing. With a little planning and awareness, you can make your water supply last longer and avoid any unpleasant surprises.
