Running only off of onboard tank

Reading people experiences with water pressure surges got me thinking about running only off onboard tank. Campground I parked at, left me 10' short of attaching to the trailer, but could reach onboard tank.

also took note, the "host" a traveling full timer, kept his water turned off, along with a higher quality pressure regulator AND and pressure gauge on his water line.

It was actually fine, and gave me a good idea on when I needed to dump grey tank. As the fresh water tank was run down, grey tank needed to be dumped :)

Have ordered an accumulator.
  • One nice thing about being "unplugged" from city water is as long as you keep your water pump off you don't have to worry about internal water leaks springing up on you while you are away or asleep.

    About the only benefit to full hookups for me is you don't have to be as stingy with the water when showering.
  • Running from tank when on a water site is a viable option at times for many reasons.
    I have done it on occasion , but I prefer to use CG water most of the time
  • We also often use the tank/pump. We almost always drive with a full fresh water IF it's good tasting water and hence no concern about the next water for drinking.

    Yes we drink water from the tank and never had a problem in 30 years likely do to the occasional treated city water.
  • I don't necessarily use the fresh water tank all the time, but there's always fresh water in it. Couple of times, there was a problem with the Campground water so we used the onboard tank, and if we leave the RV for any length of time and I am hooked to water, I shut off the water and even shut my secondary shut off at my 45degree brass fitting inline at my water filter
  • I always do.

    The campground I stay at in winter has a habit of water line breaks, I don't have to mess with pressure regulators and hoses, leaks, or run out a gallon of water to get rid of the hose taste.

    And yes, you can approximate your gray tank level by how much water you've used.
