Trouble with the gas. Help Please. Forums

We have run up against a new problem with the Gas installation in our 2006 Geist 55. For over thirty years in Caravans and Motorhomes we have used a combination of Camping Gas and Calor. Until recently we always used Propane in both with a regulator on each cylinder.
Our new van has the new layout of a single regulator fixed on the side of the gas box and we had a splitter with a gauge on it to connect the two cylinders which we worked on the basis of one off/one on.
During the early part of this year we used only the Camping Gas with a metalised gas pipe and everything worked well. Just before we set off on our latest visit to France we changed over to the Calor Butane cylinder and immediately noticed a fall off in power on the gas rings. The drop was acceptable however and so on we went . After about a week we started to smell gas and when I checked the system I found that one of the joints in the pipe from the Calor was weeping a liquid. I immediately tightened the fittings but the smell went on so I stripped the system back to the Camping gas on a single direct connection to the regulator. In other words I took out the Calor gas from the loop.
The gas smell disappeared completely and the gas rings and fridge worked fine. Last weekend we were off to a wedding and the site we used did not have electrics so we started up the Truma heater on the Camping Gas cylinder to run the water and space heating. Nothing would work and we have not been able to get it going on either.
I have booked the van in to the Suppliers next week but would like to know what may be wrong before I take it along. Can anyone help?
A couple of other points - the regulator and the top of the Calor Gas cylinder are about level and are connected by a new proprietary plastic pipe.

first the dumb question did you remove the outside vent cover?
are all the regulators the same pressure ?
is there a auto cut off for low pressure for the water heater also there was a post on here last year about water in the gas bottles

Not sure if this is any help, but there have been reports, of fluid blocking regulators which may explain your lack of gas flow?

Have a look at this link from the Caravan Club:

Thanks for your help. The Caravan Club posting seems to cover the problem very well.

Our heater does not have a flue cover. There is only one regulator for the new systems, as for the pressure cut off I can't see anything in the instructions about that but thanks anyway.
