Water tank draining while driving

After filling water tank water drains thru vinyl tube while driving. Wife was following me and notified me of this. Wondered why we went through so much water so quickly. Model TSL 2003 26' 5th wheel. How do I solve this? Tank not accessible as bottom of unit is covered with OSB (factory) Is there a valve not correctly turned? Thanks for any help.

That tube is the over flow from your fresh water tank I have the same thing when I fill my tank it starts to come out of tube but when I hook up hand start out of my driveway it really starts to flow my driveway is up hill so the only way that I have found to stop flow of water is clamp off tube till I get to camping spot when I am all set up I remove clamp other wise i loose to much water.

My tank has 2 places for water to "leak" out. The first is a white plastic spigot that is mounted on the frame rail with a plastic tube running to the bottom of the tank. This is the one for draining the tank before winter or after a trip. The second is an overflow tube that comes out of a port on the top of the tank. It lets me know when my fresh water tank is full during filling.

Does yours have a spigot for draining the tank? If so, maybe it's not closed all the way. Otherwise it's probably just excess water in the tank coming out of the overflow from sloshing around as the trailer moves down the road.

As far as I know, none of the fresh water tanks are baffled.

There is a thread on here somewhere about this, but what a lot of us have done is put a valve on the overflow tubes. I put a barb-thread fitting into the overflow tubes and then a PVC valve. Open the valve while filling the tank, close it, drive to the destination, and then open the valve again. We go through a lot less water.

Might be a stupid question, but does that overflow tube that you guys are putting a valve on act as a vent as well while drawing water from the tank while at your destination? I would think it would be so as stated above, make sure it is opened again once you are all set up......

just thinking out loud here, correct me if I'm wrong.

Thanks

My 322FKS has two of those overeflows and I also did lose alot of water.

I put a valve and joined the two overflows to stop the loss. Now I open the valve when filling and close it after. The vent to allow the pump to work is still at the gravity fill spot.

Yes, there is another thread on this forum that deals with the EXACT problem. The name of the thread is Fresh Water Tank Pukes
Here is the link. https://www.jaycoowners.com/showthrea...ter+tank+pukes

You really only need to read and look at the posted photos (same photos that dalenoel links to above) on the last page of the thread, because the first several pages are filled with responses from disbelievers stating that his lowpoint drains are open and disputing the fact that some Jayco Travel Trailers hold 90 gallons of fresh water (2 45 gallon tanks). The last page has great advice that fixes the problem pronto. His photos are very helpful. Quick fix that works...but you MUST remember to open the valves while filling so the overflow tubes can do their work. Once they begin to flow, close the valve. I do not believe that they need to be open for venting once at your campsite and using water, because my Starcraft 235fb (Jayco twin) has a small vent tube located right next to it.

And I don't believe that it is just a sloshing while traveling problem, I believe the overflow tubes actually siphon quite a bit of water while just standing still (at least mine did until I used the solution found on this thread). Apparently, this overflow tube problem is a long-recognized one with Jayco/Starcraft trailers and one that they can't seem to get fixed at the factory.

What valves are we talking about?

The one kokaneezer and the others added under their fresh water tank where the overflow tubes that have been joined together and had a valve added to eliminate syphoning.

Thanks to all who responded. I didn't know it was a common problem. I now know the cure for this problem. Wish Jayco could have done it differently. Am a little dissappointed with them.
