In my 1990 Winnebago Warrior, when you fill it with water, you just shove the end of the hose in a hole.About 1/2 the water coming out of the hose comes out around the hose and ends up on the ground. There is a vent line but clearly it's not venting enough.Any way to fix this?Steve

Obviously, the vent line needs cleared. Did you try running the water into the tank at slower flow?If I gravity fill the tank on our 96 Southwind it will do the same thing unless I slow the flow. My vent is clear snd working normal.

Maybe your fill line is kinked or the vent is plugged. Bad business shoving a hose in the filler anyway. That hose end is loaded with germs and who knows what else.

If you put the hose in too far, the hose itself could block the air from escaping. Secondly, I have a short piece of hose I use to put tightly against the vent hole and blow into it to remove any water that mlght be lying in there that may be blocking the air from escaping.

I used an old hose (actually it was new, just sitting around a long time), for a washing machine and cut it in half. Both ends have the female end. I then attach the 1/2 hose to my fill (garden hose), and simply insert it into the camper fresh water fill. The diameter of the washing machine hose is smaller than the fill hole hose, allowing air to escape around it (and the little vent also). I then never turn the spigot on full blast. I always let it fill slow.Before, if I simply put the hose on the end of the fill port, the water would belch back-up. It became quite obvious the water was filling so fast it was causing a vacuum in the fill hose and literally throwing it up back up. When I slowed the water down, it fill just fine.However, I eventually figured it out the tank was filling only 1/2 full when the water started overflowing the fill hole. Even running slow, it would cause a vacuum and then finally belch over (I though it was full, it wasn't).That's when I came up with the idea of the washing machine hose cut in half add-on. It worked great! I shove the hose completely down the neck of the fill hole, run the water a little slower, and I've never had problems since. I keep the washing machine hose right in my pass through, keep it clean in a separate zip lock bag, and use it only for filling the fresh water tank. The most simple solution to your problem is to fill the tank with a slower stream of water. Don't run the hose full blast. It will not back up and belch out that way.And by the way, this same washing machine hose works absolutely marvelous for washing out the water heater. It fits perfect in the anode rode hole and still have room to let air in (vent), and when the spigot is turned on full force, it really blasts the inside of the water heater.I have since added a garden hose turn off valve so I can shut the water off at the end of the hose and not get a bath running back and forth to the spigot, or having to lay the black washing machine hose on a dirty surface. This works fantastic. If you have a washing machine hose laying around, try it.

I also use a dedicated short piece of hose to fill the fresh water tank. I have a spray bottle close at hand that is filled with diluted bleach solution. I also have a supply of wet wipes. I will spray and/or wipe down the end of the hose before using it. I also use the wet wipes and bleach bottle for sanitation when I’m dumping tanks,.

When filling with water, most of it dumps out the side.

I have the same problem and Camco adapter was a simple fix.

Bingo! This works well, but, IMO the ball valve at the nozzle is junk. (it leaks) It helps to be able to shut off the water flow (mostly) at the nozzle instead of the spigot if you don't want to make unnecessary trips and/or get water all over the place when you fill the fresh water tank.

Yep. Amazing how simple to resolve the backflow. :)

I find the ball valve works well enough to stop the flow at the nozzle so I can casually turn off the main valve at the faucet after filling. Then I open the ball valve and let the hose drain.

I built my own fill adapter out of 1/2" PVC with an elbow and a ball valve. Being rigid I can stick it in the filler, turn the hose on slow and do other things while it fills. Won't those soft hose ends kink if you don't hold them the whole time?

Slow flow and a Camco filling device solved my problems. Vent just doesn't allow enough air flow out of tank at fast fill rates

Absolutely! OP, do you rinse the hose end and then spray with bleach?

I'll try the cut-off piece of hose.

Turn the supply tap down to reduce the rate of flow.

That will solve the problem.

Due to poor design I have to feed my fresh water tank slowly or, like yours, fresh water is forced out around the hose. To add to this bad design my tank feeds from the side so you can never reach intended tank capacity. Soon as a left hand turn is made water comes out the fill inlet. I put a short piece of hose with no male end on my fill hose. This takes the water outlet into the tank so air can more easily escape. Helps but does not cure

Take a stiff wire with a rounded end and push it down your vent, turning if necessary to get it to go to the tank. Next put that dirty hose into the fill (Helps to build up your amunities :w) and try and seal it so you can build pressure and hopefully blow your vent clean.
