This article is written around my 2009 Bailey Senator Arizona – but this could probably be done on many other caravans that already have an on-board tank (or you are fitting a tank).
On holiday in France recently, we had problems (yet again), with the O rings of the Whale water inlet (connection to the external barrel), such that I couldn’t even fill the onboard tank properly (which is a pain in itself – messing with manual change-over valves!).
It occurred to me then that if I *could* fill the onboard tank (even by pouring water in the top), I wouldn’t have to bleed the air every time the offboard tank ran out of water! (I have already fitted an Audible alarm to the low level warning light for the onboard tank -which you can’t see on the Bailey, unless you make a point of looking!).
I couldn’t find my spare O rings at the time, but I fixed the external filler using “gas grade” PTFE tape (thicker than the cheap water stuff), that I always keep in the van as part of my “first aid kit” (good to refit worn screws for example). I wrapped it around the damaged / missing O rings.
Anyway – I decided I wanted an “auto-fill” to my on-board tank – similar to a modification I made to my Lunar around 20 years ago.
I looked on the market – there is NOTHING, nothing on Ebay, Nothing on “The Web”, nothing on YouTube, nothing in the Forums on how to do this… No gadgets, no advice, no discussion – maybe I’m the only one that wants this ????
So here is how I did it on my Bailey Senator:
Oh – and BTW if you came here looking for “Tracker” – I will also tell you how to replace the battery in your On-board (hidden) Tracker device. (Bailey Senator Arizona only – Other Bailey’s may be similar!)
