water problem

Jeepit · 06-19-2015, 07:38 AM

After we fill camper with fresh water and drive to campground sometimes more than 1/2 the tank is gone.
What are we doing wrong?

Multiple threads about this. It siphons out of the overflow hoses. Some have, including myself, added caps on the overflows so I can get to my site with all my water..

When I fill the fresh water tank I go inside and turn on a faucet for bit and that has helped us from not having the water siphon out the overflow valve.

^^^ what they said and...

Wasting gas or Diesel.

Our fuel mileage went up 20% when we stopped doing that.

Find a spot close to the campground to take on water. The drive on the highway will be more pleasant too.

Also finding a proper place to dump tanks before hitting the highway home helps too.

For me some State campgrounds here in NY the water is near the office. Then you have to drive to your site, maybe 1/2 mile into the park. And that is where I lose 1/3 of my water. Not driving down the highway wasting gas.

Definitely find and plug the overflow line!

I know Winding Hills (a county park near where I live) has some steep hills between the office and the campsites.

So I have 2 tubes coming down near tank. Are these the culprits?
And what type of caps are you using to seal off?

Anything that will seal 'em off and stay in place. I had some automotive vacuum service plugs lying around.

I extended mine to be near the fill location so I could reach them. I used garden hose males ends and screw caps.

Wish I'd thunka that instead of lying in the mud twice!

No those are the lowpoint drains in most cases. On the 5'er there is a black flat hose that extends through the belly covering usually near the drain spigot. If you fold it over and clamp it that usually does the trick, just remember to take it off once you are level.

On a TT I cannot say what that hose looks like.

The way I found it was the hose with water coming out when I overfilled the tank. Clear plastic, just ahead of the FW tank, slightly to starboard 1/2" ID.

My low point drains are nowhere near the tank. They are upfront under the bathroom. My overflow tubes are right under the axles..But like mike837go said, look for the overflow when filling. It looked similar to Niagara falls in the rainy season..

Those two tubes are probably your low point drains. To find your overflow, fill the tank to the top and your overflow is the tube with water coming out under the trailer.

My 2010 29BHS has two clear braided hoses that come out just near the tank. (running below the underbelly liner) They start to overflow when the tank is full, and it does siphon out of the tank almost 1/3 of the tank. I bought some hose barbs with threaded end, hose clamps and pvc caps from home depot.
When when it starts to come out the overflows, I put on the caps, (finger tight only - it still drips a little, but not enough to worry about) When I get to the campsite, I put the dog's water under the overflow and catch the few drips.
Since I always dry camp its the best modification I have done. I used to always run low on water before I did it. Now I arrive with a full tank and have not run out yet.

Fold the overflow hose over and use a reusable zip tie. What I do. Spark plug works too.

oldmanAZ · 06-23-2015, 12:12 PM

I was wondering about trying a large binder clip, something like this...

I'd try it and report but my TT is at the dealer getting a FW tank leak fixed.

silverark · 06-23-2015, 12:47 PM

I was going to try a pair of these.

Cosmik Debris · 06-23-2015, 12:58 PM

What gets me is that some of you show models newer than my 2013 and this is still an issue. Obviously they have too long of an overflow outlet tube in the fw tank. Why? It only needs to be barely extending into the tank. Instead of fixing it we all have plugs and clamps and zipties hanging down.Throw Ellie Mae up on top with granny to complete the picture.
