As discussed else where, we are experiencing a leak in our new Hymer Exsis i water system.
From what I can gather from others mainly @Lenny HB the internal filler cap (blue) is below the top of the tank, see below for those not familiar with Hymer water tanks
Now to me this is just plain DAFT !
After draining the tank and as much of the leaked water I could find, I traveled 20 miles, after which there was just a very very small amount of water in the garage .... so I assume this was previously leaked.
I then filled up the tank ........ at full it didn't come out if the external filler cap but started to drain from an over flow pipe under and in the middle on the van.
Looking inside, there was water coming out of the blue cap and sure enough after returning 20 miles home, there was a lot of water in the garage. So without at this point running the shower etc to see if there is are any further 'pressure' leaks, I think I've identified the problem.
So it appears that with out further action, running with full water is not an option
My dilemma & question now is should I run a beed of seal around the top of the blue cap (or indeed even around the threads ) to seal the system ? Obviously around the threads would likely to be permanent so around the top would be the best idea
What do other owners do, if indeed it is a design fault ?
