FAQ: Plumbing – Fresh Water

In all T’s the water filter only filters cold water going to the galley sink, no matter if the water is from the tank or an outside source.

If you find that water is coming OUT from the City Fill or Tank Fill inlet when you have the water pump on it’s likely an issue with the backflow preventer at the inlet.

If you take the cap off of the inlet you will notice that there is a screen filter inside. Remove the screen filter and turn it around so the bump is towards the outside and not pressing against the backflow preventer and that will usually stop the leakage.

If that doesn’t stop it then have the backflow preventer checked out and/or replaced.

Your Pre – 2022 Travato has an inlet on the driver’s side labeled “CITY FILL”.
It doesn’t “fill” anything, instead it bypasses your water tank and provides water to all of the plumbing fixtures using the water coming through the hose.
Your 2022 or newer Travato has a Nautilus Panel with a “”City Water” configuration.
This sounds great at first until you consider the potential negatives:
1  It’s one more thing to have to hook up or unhook, impeding mobility.
2 If you have a leak someplace you won’t know it until you see/feel water flowing and then you have to run outside to the end of the hose to turn it off.
3 The water pressure in some campgrounds is less than the pressure from your on board water pump.

The majority of Travato (and other Class B brands) owners don’t use CITY FILL or CITY WATER except to flush the lines and fill the Truma during the de-winterizing process.
Instead they use the water from the on board tank and only turn on the water pump when actually using water and then immediately turn it back off.
If you have the pump on and hear it running when you aren’t actually using a plumbing fixture it’s a immediate signal that you should be looking for a leak someplace.
When you are using your fresh water tank, you cycle the water in the tank and thus minimize any buildup.

Travato Water System Configurations Set V1-1

The kitchen and bathroom faucets should not drip when turned off, however the shower head may continue to release water in the hose after you turn off the shower. That shower head dripping is normal and is not a defect.

However, in all cases, it’s a smart practice to turn off the pump whenever you’re not using the fresh water system. In the event you did have a leak, having the pump turned off would prevent you returning to your RV and discovering a major surprise.
