When there's enough lime and shite in the system you never get a leak with a cylinder!!

I've gotta ask this. I've never fitted a HW cylinder but think the connectors are compression? If so, why are they any different from any other compression? Tom says in his video you can try to nip them up (NOT the HW cylinders though). What is special about them?
I'm guessing that one of the problems that Tom was referring to is not so much the unions/connections themselves - but the copper around the unions on the cylinder. After years/decades it can go a bit thin and tear easier. So if some ham-fisted oaf attends a weeping union on a cylinder and decides to try 'nipping' it up with his 36" Stillies - the metal around the union could tear leading to instant tsunami effect. As well as tearing the metal, it's not a good idea to disturb these joints too much.
It's like the other day I was swapping a leaking auto bottle vent on the primaries to cylinder. As I gingerly undid the old vent and installed the new one, I was careful not to put any strain on the pipe from vent to the union on side of cylinder a few inches along the pipe.
Same when changing a motorised valve on the primaries to cylinder. When you take old valve off, you have to be really careful not to move the short length of pipe that goes from valve to the union in the side of cylinder. Any stress or leverage on the pipe that is free at one end where the valve is removed could result in tearing the metal around the union in cylinder.
Get it wrong, and it's new cylinder and plenty of

Nice video but in situ how easy is it going to be to crack that nut open esp without disturbing the compression ? Also do you have to use hemp+bossWhite - what would you use ?

I have a poor record with cylinder leaks as I find there's always limited access and the fittings have been nipped up before the tanks in it's final location so I'd rather just replace the cylinder. |

Ongoing joke with boiler fitters, don’t repair just tell customer they need a new boiler I’m not laughing |

Ongoing joke with boiler fitters, don’t repair just tell customer they need a new boiler I’m not laughing They paste and fiber wash them at install and that paste takes a good whack to move it so it's a job on my terms. I don't want the "how much"!!!!! In the ear after they think there getting fleeced. |

I mean I could imagine not wanting a job like that espcially if it did gush out. Would you really want the hassle of so much damage being claimed from you? (and could be worse if someone gets scolded) Makes me wonder if dereton should go around making such a job look easy? I suppose if its your own its worth a try. |

I've walked away from many because the custard is thinking, a quick turn with a wrench £10/20, So I educate them that it needs to be drained off first to avoid major damage, I can read their thoughts as I say, " listen, I'm on my way to another job, you have a think and let me know" I think one in ten is about the number who call back and agree to let me drain off, Its possible that one or two chance it and get away with it, but I'm not about to play Russian roulette is someones house, NO SIR  |

I tried getting the fittings off an old one with a lump hammer and chisel. Wouldn't budge. Paste had turned into concrete!! |

Don't know of any videos of Cylinder repair in situ, it's always replace or doing stuff with it when it's out. Don't have to use hemp and boss white. Right amount of PTFE + paste will do as good as hemp. |
