very slow filling water tankson jayco.

I think you have a problem. I've never heard of this sort of installation on any camper van.

Might be a good idea to ring Jayco.....something does'nt sound right.

Briggzee,

From my experience the caravans and campers that I have owned are relatively slow to fill.

Inlets on the bottom of the side of the tank are reasonably common and most are around 25-30mm diameter.

A few things to check out.

1.Are the breather/overflow outlets blocked. These are usually on top of the tank and dribble when the tank is full.

Do the tanks have breathers lines fitted. Probably not.

I made up my own using PVC trickle fittings, plastic hose and high grade sikaflex (not any old silicone ) I used a Ryco universal fuel filter at the open end to keep out bugs, dust etc.
These help to speed things up but the tanks have to come out to fit them. They are 12.5mm plastic hose and have a filter of some sort on the open end. This end must be fixed at least 150mm above the top of the tank

2. What size filler hose is fitted and what diameter tank inlet, the tank inlet is the limiting factor.
Anything under 25mm will be slow

Not much else I can suggest

Hi Craig

I never fill my twin tanks from the filler cap.

I have fitted valves between them on both inlet and outlet so I can use them one at at time. This also prevents you loosing all your water if one gets a leak.

I pressure fill my tanks one a a time from the drain tap until the water starts flowing from the over flow. This way I get 2 full tanks with no air lock.

Hi
briggzee
It is possible that the vent lines going back up to the filler have a slight bend in them and are filled with water that will give a restriction for filling. Have two tanks on my caravan and one fill point have both bleeds hooked together and have no problems filling tanks. Both tanks inlets are pipes halfway up tank. Breather lines are dripper tube have dripper filter to stop bugs ect entering system.
