Soldering has become much harder, normally doing 15mm and 22mm Yorkshire fittings around the house has gone fine. suddenly things have got a little harder, connecting 35mm straight connector to 35-28mm reducer to 28mm straight connector with 15mm T to 28mm 90 then another very close. The whole lot crammed together in about 250mm all with end feed fittings. Grown up soldering! My attempt was not a pretty sight. Things got very hot and nasty with burnt flux and the joints wouldn't run.. I changed the gas on my blow torch for map gas bloody hell that go hot! I have pulled it out and I'll have another crack at it tomorrow. I am now in post disaster trauma and have had to go into severe Boddington therapy. Are there any plumbers out there that can give me clue. I promise never to say anything bad about plumbers again. A frustrated chippy.

if your soldering 28mm or above, forget a rothengerger type torch if thats what your using, you will need a bigger flame on it for that size, solder wont run properly as you wont get the heat even around that size of fitting :LOL:
 
Pity you can't manage a heatmat yer bastid. :LOL: :LOL:


Couldn't resist that dan, don't hit me.

:LOL: That was supposed to be a totally flat rig with plenty of space in between for installation pipes. Pre-built it and took it to site (off drawings) and the builder said, without skipping a breath, "hope you don't mind, we've made the boiler cupboard 450mm narrower".

Git :LOL: had to adjust the thing in situ....
 
Builders eh :mad:

I hope you said..."I hope you don't mind, I'll be billing you an extra two hundred quid" :mrgreen:
 
Nah, he's one of the good un's... but I do get the odd ribbing over scorch marks now though ;).

Made a real effort on the last one.... But then the git added an extra room to the UFH and now I have to wire up another damn manifold to my S-Plan ++++.... Think I need another wiring centre ;).

Pays "normal" rates, so shouldn't complain too much.
 
Mounted on plywood !!!!! icon_eek.gif icon_lol.gif

Never had a problem with that, and that is with maker's blessings (not the man in the sky :D )

Exterior ply and screws give good fixings. Have done that by fixing 3?4" ply to wall with no nails and fixings.

Nice pipework Dan :)
 
Cheers Danny ;).

Mounted an SB30 on Ply today as it happens - albeit with 10mm on concrete render on it too :LOL:

Another Keston in the skip... how many more left now?

You definitely need a heat mat :p If it`s all in situ because you need to get the flame all around the fitting :idea: and you want butane not mapp gas - you want a lower heat and not concentrated in one spot , like you can get away with on smaller pipe/fittings . Also lead solder will flow better than lead free ( it`s a pain even on small fittings :evil: ) I find La Co flux is good too
