Water Leak??

[spike43]

Afternoon all:

Filled my 2011 321 RLTS fresh water tank to almost full at home. Got to campground (dry camping) and fresh water was only 1/3 full.
Cant see any signs of a leak.
Any ideas

Was your low point drain valve closed all the way? Could have filled full enough it spilled out the overflow too....

Welcome the to the wonderful world of the overflow tubes!


Every time the water sloshed (accelerate, brake, uphill and down) some water went out the overflow.


Find them and cap them with valves. Open when filling and camping. Close during transport.


Or, we have water filling places near where we camp. It takes a couple of days to collect a full tank. But it better than hauling hundreds of pounds of water several hundred miles...

Having the same problem. the dealer is looking into a fix from the mfg.
for now just folded the soft rubber nipple on the end of the overflow and put a tie wrap on to hold it folded and that stopped the problem

You'll have to undo the tie wrap when camping or filling. The tank needs to breathe when stationary or the tank will be damaged.

Only pinch off the vent when traveling.

As has been said, a lot of water can leak out of the overflow tubes. Though they come out of the top of the water tank, often a siphon effect can happen. Putting a valve on the tube end underneath the trailer will work to stop this. Fill the tank till water comes out of the overflow and once the flow stops, closed the valve. Since your water tank fill spout usually always has a breather hole/tube (Usually, just above and left of the fill spout, just a little smaller than a dime sized hole with a screen), you needn't worry about opening the valve underneath until you go to fill the tank again. The breather tube will allow the tank to breath.

Thanks I forgot to mention that important point.
I do leave the small vent hose open to prevent pressure from changing as I go up and down in elevation.

So has anyone taken this to the dealer for repair? If so what did the Mfg say?

Update:
talked with the service rep at my dealership today. He said this is common on many brands of RV and they fix it by just re routing the overflow pipe. I will update after the "fix" and let everyone know if it works.
