Fresh water fill line

[billyray50]

Noticed than when I have tried to fill fresh water tank the water would just pour out. Looking back when taking delivery of TC at Truck camper warehouse it did same thing. In my haste doing PDI after TCW set up camper on truck and setup in their full service sights overnight I thought tank was full already. Spoke with Adventurer service rep and was told it that Fill hose maybe kinked or slope is not correct. Went and purchased a 4' 1/2 inch water hose and cut the end off. Shoved the piece of hose down fill port and definitely felt some restriction but got hose past it and was able to fill water tank. Looked online and seems to be common problem with all types of RVs. Any suggestions?

Good luck Billyray. Just filled mine up again the other day (same exact camper) and did just fine. Must be kinked or blocked. Hope you get it figured out soon and feel free to PM me again anytime if you want me to reference things or such.

Thanks will do...

I agree the obstruction is somewhere in the distance your new hose covers.
but this obstruction is not nessassarly a Kink in the hose.

See in the picture where after pipe goes over copper line, than sags before going up into basement? if that sag is enough that water can fill 100% of the line that same water is going to cause a block, preventing additional water to get into tank unless you pressurize the fill side to force this water to keep moving.

by bypassing this sag with new line your introducing fresh water after that sag.

a restriction in the vent line can compound this water stuck in the low point of the hose.

Well I would agree other than the fact if you look at the my pic showing fill line the water tank is all the way in the front of camper so no way the 4 foot hose enters the fresh water tank.

It means the obstruction is somewhere in the first 4' of the fill tube.

You already shoved a hose down the fill tube and determined that there was an obstruction. Once past the obstruction you could fill just fine.

That means the vent tube is fine.

The obstruction is in the fill tube.

I agree.

I will throw in my 2.74c here.

I have never seen Billyray50's problem in person, but I did camp next to him one night :).

When he pushed the 1/2" hose into tank fill line, I bet it went all the way into tank entrance, now the Larger fill tube is acting as the vent tube since the actual fill is through the 1/2" inner house.
The say way a coax hose that are now used at gas station pumps works. There is an inner hose that delivers the product (fuel) and outer hose is the vent of fumes back into the station vapor recovery system.

Whazoo, i did try and blow thru small hose covering vent line. After blowing in as hard as i could the air seemed to come right back out? Maybe vent line is kinked?

Why not leave new hose in fill line?

As I needed to use a piece of hose with cut off end anyway-after a few times pulling it in and out I realized it could just live there. Filed off about 1/8" from female hose end so cap would screw back on.

Ours just chokes, no kinks-fair slope but unless filling really slow just easier for water to come back out. No issues with the additional hose, also vents around it. I only pull out enough to attach hose- inch or 2

Only caution is with the added hose, too easy to turn water volume up since it will take it, but also easy to pressurize the tank. If I can hear the air I turn down.

That is an idea !! I will that tomorrow. Thanks.

I'll double on the vent tube as a possible. If it has water in it it will act exactly the same as a kinked fill hose. Pucker those lips, ok or get a small section of vacuum tubing and cover the vent hole. Now blow! And jump back cuz that will pressurize the tank making for a cool shower as the water shoots back out the fill hose, just like a kinked fill hose will. Actually Ive had both issues in different rv's.

Wouldn't hurt to continue using the 1/2 hose. A benefit of using it allows the tank to vent right up the fill pipe.

Good luck Billyray. Just filled mine up again the other day (same exact camper) and did just fine. Must be kinked or blocked. Hope you get it figured out soon and feel free to PM me again anytime if you want me to reference things or such.

Yes Bedlam i think so too. In first pic the freshwater line lays over that copper pipe and from my view since i cannot get in that far in basement storage hose has a narrower shape to it.

You may not be able to get your head in that far, but you may be able to take a picture with the flash on and your arm extended inside (even better if you have a selfie stick).
