Hurrying to lay in some *first fix* plumbing before gluing the floor, I
was in two minds about testing for leaks! What can go wrong with a 15mm
copper, well cleaned and fluxed Yorkshire straight connection?
Well, the suspect joint was actually in a sleeve roughly in the middle
of a pair of floor joists and only found with a liberal dose of dilute
Fairy!
Hmm.. The current offering from Screwfix don't show much of a visible
solder ring.....

While we are on the subject... my current gas blowtorch is probably too
small for 28mm pipe. Does anyone have a recommendation for a better one
using a readily available gas canister?

If there is no solder showing clearly and continuously around all ends
(use a mirror and torch) no point in even testing it. Do it again. Hope
you aren't paying extra for solder ring fittings.

Just my opinion but you need to be really careful using the higher power MAP
blowtorch on 15 and 22mm fittings its very easy to overheat the fitting and
burn the flux and end up with a useless joint
why not get one of these and a small 3.9kg Propane Gas Cylinder

I'm doing some plumbing using a Surefire2 and MAP

https://www.amazon.co.uk/Rothenberge.../dp/B000TGNDO0.

The torch is adjusted to _MINIMUM_ flame for 15mm and 22mm solder ring
fittings and so will cope with 28mm with ease.

With MAPP the torch lights instantly on the piezo ignition and works at
any angle. This means that I can always put the torch down without a flame.

As did I. Unfortunately it doesn't seem possible to produce a visible
fillet with the lead free solder - this was always reassuring with
tin-lead solder, now I always pressure check mine for 24 hours in case
of a little track of flux through the joint.

They are roughly twice as much as end feed but even a farmer on a

It was well over 40 years ago when I was installing central heating. Metric
size was coming in as I was getting out. Pressure testing was unheard of
then. All I can say that is that the extra bit of solder from a coil of
solder worked. Dunno about the joints under the floor boards. I was and
still am 6' tall and was not going to crawl under the floor boards again to
check.
The blow lamp was a big blaster from a big gas bottle. A bit of asbestos
prevented the skirting boards from being burnt. Well, actually it didn't.

The thing is ... they (I have one) make doing any such job so much
easier, like playing a quality instrument over a cheap one.

And with things like soldering there is a bit of craft involved (where
using a decent tool is a good thing and makes the task easier ... and
in the case of working with a live flame, possibly safer)?

Toolstation do a turbo torch and

And when they are selling off your tools will be worth little, versus
the Superfire II. ;-)

So, you aren't really talking about the £55 (£15 for the bottle) from
Amazon or the £66 all in and delivered from eBay (eg 172242135947) but
just the extra ~16 quid (over the SF offering that you may or many not
to be able to get parts for or service on?) to get something 'known'

If you've got nothing with you, you can top & tail 2 food cans, slit & flatten them and put wet cardboard between them. Re-wet for each joint.

I replaced my Bernzomatic quickfire recently[1] with a Rothenberger

Been very pleased with it. Even on propane (it will also run MAPP) it
has plenty of power (you need to throttle it back for 15mm joints). Very
nice you use. Pull the trigger and it lights and runs at the preset
output. No flare, no warm up, just straight into it. Let go and it stops
immediately - so you can just let go and not need to think where you are
putting it etc.

Which is why we use 2% hard silver solder in australia,(or used to, now
often as not they use various plastic pipes and crimp or push fit
fittings)(which fail more often)
I have never had a hard silver solder joint fail.

The words "heat resistant" rather than "flame resistant" seem to be more

back. It does however protect wood etc. behind the work-piece.

OK. My current torch is not a screw fitting type. I think I'll go with

small joints.

I will use end feed for the larger joints which are mainly up near the

Solder ring fittings are usually a little longer to compensate for that.
So the amount of surface area that ends up soldered together is similar
in either case.

I always use end feed just because I find them quicker (they take less
heating), look neater once fitted, and they are cheaper (I buy bulk
packs). Having said that, I keep a few solder ring fittings to hand for
those jobs where you have to work one handed.

The thing is that you can, not only control the flame fairly closely
(I wouldn't say it was *particularly* powerful etc) and use it in
various orientations without it looking more like an angry dragon. ;-)

I will use end feed for the larger joints which are mainly up near the
ceiling as I am ducting the pipework to avoid cutting joists.

I think the trick with many soldering jobs is to warm everything up a
bit first, then heat the joint and the material immediately either
side and watch the solder run (and then leave it alone). ;-)

But then you'd have to use compression fittings. Anyway, it doesn't buy
many, especially odd ones or 28mm.
