Greetings to anyone who has an older Jayco Journey and can help with this issue. Just got this second hand caravan and am getting ready for a first trip. Tanks won't accept water through the 50mm white plastic fillers. There's clearly a lot of air pressure generated when I try to fill, even with sink tap open inside the van. I can't see any breathers on the tanks, and have checked the filler lines for obstructions. What am I missing?

Welcome to the gang Roger, enjoy here and out in the playground.
Not sure if your greetings cover me or not as I din't have a Jayco.
May I suggest you do a search in the thick blue line above as this has been discussed before. Heaps of info down in the dungeon.
Keep Safe on the roads and out there.

Welcome to GN's Roger, I used to have a Jayco Journey (great van) until 2013. The water tank was always having air blockages when filling - I adapted/fitted a 30cm piece of 12mm clear plastic food grade tube to click connector to fit on end of water hose - just push the tube down the throat into filler which allows air to escape past the outside of tube thus eliminating air blockage. I still use this methodology in current van. Less than $10 fix of annoying problem.

Imperative not to pressurise the tanks because you will break supports and or lift the floor above
Even 1psi (2 foot water column) in a large flat tank can provide a tonne or more bursting force.

Thanks for that Tony,
How does the van isolate the mains pressure when using that connector in a van park?

Thanks for the tip Possum3 - I'll give that a try.

Welcome to the forum, RogerHTas
This seems to be a common fault with Jayco caravan and Motorhomes, not sure about other makes
The main problem seems to be that the water tank is inside the chassis rails, while the filler point is outside the chassis rails
The inlet hose has to then go under the chassis rails, in a "U" configuration
Possum idea of pushing a hose around the "U" section, and into the tank will work, as I had done it on a caravan
You can also fit another hose into the tank, (alongside the original), and use a snap on fitting, to use pressurised water to fill the tank
But...
You have to know what you are doing, because as others have already said, doing it wrongly will cause problems

I presume previous owner fėlled tanks ßo onč check with owner or jaýco ßervice. Failing that check where water tube goes into tanks should be easy to follow. i have starcraft. The connects from inside van wiill most likely be back of cupboard even put some colouring used in icing to checlk which line goes to which tank. I havE 3 waterpoints centre one has hose connection for town water, one connection each side is to put hose into to fill tank, can get a rubber type adapter to fit over connection on van and then mae up coonection to go onto hose . Go to bunnings , i buy there or an
irrigation outlet. Good liuck

Important note; Jayco use "one and a quarter inch American" threaded fitting on their water inlet NOT BSP threaded
