We have been losing anti freeze from the engine so when Hilary stripped the bed yesterday I took the opportunity to check the hoses to the calorifier only to find a leak on the calorifier it self.
So a £500 later a new calorifier and expansion bottle which meant total re plumb and rewire the immersion heater.
After a lot of water and a couple of leaks I completed the job today.
Moving out of the marina tomorrow and in for blacking.
