Bit long in the tooth for a tea boy. Spent most of my working life around gas at up to around 1000psi, so had plenty of opportunity to learn a wee bit about it. As for knowing it all, I certainly know a hell of a lot, but unlike some on here, have always thought that the more I learn, the less...

Please learn to read. It's not difficult. What I wrote was "I found the first on the first system I had - a nice wee flame on a coupling". In simple terms, I opened the cabinet, and found a flame on coupling. Coupling loose, gas leak, gas ignited, flame. Simple.

Don't know how good this brand is but, in any case, these materials, which tend to be polymer based, probably won't work on anything that isn't straight tube, due to lack of conformity I remember using http://www.loctite.co.uk/metal-filled-compounds-4485.htm about 40 years ago to repair an...

Where did I say I checked for a gas leak with a naked flame. Suggest you learn to read. Headaches from a gas leak? Yes. Quite common. I suspect I can safely say I've spent more time in gas contaminated atmospheres than the rest of you put together, and yes, it'll give you a headache. I said...

I'll try and respond to your various comments. Photos - no need. Suffice it to say that of the 16 pipes, possibly two aren't like bananas. System was installed when house was new, so no excuses. Calling him a Muppet was kind. Various comments forgetting that appear to ignore what I'm asking...

Again, you're missing the point, as was Diialio. (Where are his jokes?) RTBQ!!! There's not enough space to, as you say, control the flame, in any other way than physically blocking it with a very thin barrier/deflector. I accept that you will have made far more of these joints than I have, but...

I know it can be done - found this a few days ago. http://copperplumbing.org.uk/sites/default/files/content_attachments/jointing-capillary_0.pdf What I was trying, and failing to get was some input as to how much oomph you need out of the hot air gun. So I'll get out the heat gun and do a dry...

The lack of space makes the job difficult for anybody. It's not capabilities that are the problem, other than the muppet who installed the pipework. It's the simple laws of heat transfer. I might yet get tempted to do a trial run with a very big and old soldering iron. If all else fails, I'll...

That's your third comment, none of which have been either helpful or relevant. Suggest you go here https://www.bing.com/videos/search?q=do+you+want+a+five+minute+argument+or+a+ten+minute+argument&view=detail&mid=1EE1967297EF7DD368CD1EE1967297EF7DD368CD&FORM=VIRE

Didn't think foil would stand up but I suppose the heavy duty turkey stuff might. I've got a couple of mirrors - one dentist size from a GEC switchgear toolkit, the other's an extending one from a RR toolkit that you nearly need a telescope for a full stretch. The solder I'm referring to is the...

There's so little space I'll probably have to use a thin sheet of metal to protect the wall/skirting. I'm fitting 15mm valves for new radiators, so cutting out isn't an option. It's not even going to be easy to check for the solder line on the bottom of the fitting - dental style mirror should...

I need to solder a couple of fittings on 8mm copper, but the numpty who installed the system decided he'd try and make them as awkward as possible, right in a corner, making using a blowlamp fairly awkward. Anybody tried using a hot air gun?

The problem I have with soldering is the location of a couple of fittings - tight into a corner. I thought these might be the answer to my problem, but have no experience of the quality or reliability of these reducers. All my compression fitting experience has been on stuff like Swagelok and...

Are these https://www.plumbcenter.co.uk/product/center-compression-one-piece-reducer-15-x-8mm-p543541/ or these https://www.bes.co.uk/15-mm-x-10-mm-reducing-set-dzr#product-details-tab a better option for fitting 15mmTRVs to 8mm and 10mm pipework rather than use soldered reducers? If so, which...

I'll repeat - Attitude - a settled way of thinking or feeling about something - and you certainly appear to have a settled way of thinking or feeling about 8mm pipework. I don't see why you're spitting the dummy. Anyway, it's 8mm and that's the way it'll stay, albeit with 15mm tulips added...

Well that's a strange comment! Attitude - a settled way of thinking or feeling about something - which seems to reflect your comments regarding 8mm. "Don't understand your attitude to 8mm. Explanation might be interesting." - Surely that's a simple enough question to answer? What's so bad about...

It's not a pure shear load. To be pure shear, the line of action of the load would have to be vertical at the point of load, which it isn't due to the bracket being between the load and the load point. Don't understand your attitude to 8mm. Explanation might be interesting. The pipework's the...

Thanks for the replies Radiator sizing isn't a problem. I'd forgotten about tulips, so that could well be an easier solution than trying to get 8mm olives to bite on old pipework, and opens up a wider choice of valves. Changing all the pipework to 15mm isn't a viable option, and there's no...

I need to replace some 35+ year old radiators, sizes below, and I’d like to pick your collective brains. Length Height Pipes c to c 1440(Double) 700 1520 800(Double) 700...
