Hi Steve, I was advised to use glycerine by a US Watermaker company but that was about six years ago. You could ask Rod Boreham who is the UK Agent for Dassalter. He seems very switched on and helpful. His Email address is rod.boreham@advanceyachts Amel could tell you how to purge the kinks. Luckily we do not have to worry about frost in Malta!
