Confidence shot to pieces but I better pick myself up coz I have to fix it today. So I put in a new towel rail with needed pipework alterations. Filled the system back up and it looked good. I even bled the new rad valves a little so I could see water coming through. Turning on the heating and all looked great - no leaks. Came back after about 20 minutes and still no problem nice and dry. Feeling good, I went and got a beer for the evening and relaxed. An hour later I walked into the kitchen below the radiator and it was raining. Ran back upstairs and the compression into the valve on the left was peeing out hot water !!! Anyway, as a DIYer I've never seen that before. The only thing I did different was use that big blue SILVERLINE spanner to tighten up - I almost always normally use a particular pair of adjustables that I'm used it. Is it possible I over tightened? But then why didn't that show up immediately? When I examined the pipe I wouldn't say the olive was kinked as such but it had dug so deep into the pipe it had created a kind of grove for itself and you could see the pipe deformed as it was constricted. I could free it with a pair of grips but then it just spun in its grove and wouldn't come off (leading to the next stupid thing I did which I might post later) Attachments:

Ouch. Sounds like you over tightened it Dafty? Probably expanded as it heated up, then  What happened next...?

That's brilliant Karl ! That must be it and that was thing that was bothering me the most - the fact that I didn't understand. It makes sense it would have taken some time to get hot esp as it wasn't in use so just relying on the pipe conducting. It was also a copper olive which presumably is softer and most of my olives Im used to are brass but I think it was that fat spanner that encouraged me to tighten it too much. If I get any more kind/constructive replies I might feel able to own up to what I did next (after a couple of beers !) |

does the valves have those rubber seals on them, like a thin O ring ? I've had trouble with them in the past,

Not sure about the brilliant, but...thanks.  I did wonder if the olive wasn't "square", as you said it wasn't deformed, suprised on that being copper, but it probably would have been obvious quite quickly. More knowledgable ones will have a better idea.
Maybe we can all have a guess on the next bit?
Tried to squeeze the pipe "Round"?, Cut it, now too short?

The cause of your issue was using anything made from silverline
Get all of your silverline tools together & bin them.
Never mention silverline tools again
But it sounds like you over tightened it. As long as you fixed it then you’ve done a good job.

Having tried to use spanners for a few decades, it does effing grate me when grips are used!!  Even "adjustables"...
Sadly, I'd go for the shitline, just...  |

I feel over tightened as murdering fittings to death is common.
However. It's also possible with either not deburring the pipe or the pipe had a bit bending former damage possibly?

Right, well all's well now at Dafty Towers. What a bloody 24 hours. From one laurrel and hardy episode to the next. THREE times I tried to solder that yorkshire today even though yesterday it soldered fine. I really should have known better. Because I was stupidly panicking a bit I didn't really notice that the solder wasn't flowing well. It would sort of "paint on" to the pipe but not really flow or especially flow around it. And yes the reason for that was again my big problem with soldreing which was water. This time I put my vac on it for a bit (it sucks water for ever if you let it) and then for good measure put it to blow back down the pipe. Seemed to help and I got the job done. I probably should have used a stronger flame too. I'm still a bit worred about that compression because surely if it was over-tightened it would leak from the off. It was dry as a bone for a good 30 minutes. As my fellow non-plumber says and could he be right that it was the heat that triggered it ? Attachments:

You can see hassle straight away as access is tight and gulps f water in that situation would catch anyone out! |

Dafty dear boy, all you need to do is ask!!
A Ladder TR sits higher up on the wall matey - 200-300mm from the floor to the bottom & you use Straight radiator valves.
That just looks ‘Daft’😂😂🥺
