I have a hot water cylinder which has low carbon steel pipework to it - I have tried to add some pictures
I need to replace the cylinder because it is leaking and I am not able to find anyone who is comfortable to work on this this because it is barrel steel - Has anyone worked on this kind of system before?
1) It i try and put some stillstons on it am I likely to get the nut to crack and the thread to remain intact? This looks like heavy duty commercial pipework so I am nervous but I need to get this reduced to copper so I can replace the cylinder - I have found a shop which has black iron fittings that can thread onto a 2inch pipe and reduce it but it depends on geting the but off in tact
2) If I have to cut the steel pipework without a thread can I use a Priomfit compression nut? Are these leak proof and reliable for water?
