Calor Lite Bottles

GlosJive

Hi, converted over to the Calor Lite bottles last year and have experienced 2 out of the 4 calor lite bottles to leak when connected up.  With the second leaking bottle called in to the caravan centre for a safety check, they advised it was the hose connector
onto the bottle that was faulty.  Changed this to no avail, so now believe the bottle valve to be faulty.

Has anyone had a similar experience or have I been unlucky? A new experience after over 30 years of caravanning.
