Hi Meir
With your help, we have found the leak. It is coming in through the black steel panel that is bonded to the bulkhead. A small water test has proved this now that everything is out. I am not sure if anyone has attempted to remove this in the past. I wouldn't want to risk damaging the bulkhead. Second option is to try and seal the panel and test again before putting the heater box back. Any advice would be welcome.
