Laco.

That's it. I've heard enough. I hate that stuff. Bloody awful flux.

I've tried it. Then gave the tub away twice. I have no idea why it's popular on here. Most blokes I've worked with have reckoned it's crap too.

Burns too easily if you use Mapp and you're sweating 35mm+. Larger fittings need a bit of heat in the fitting, Laco starts to turn black before the solder runs properly. I hate that brand big time!

I found the Powerflow turned black that was the main reason I decided I couldn't be bothered with it. I only ever use propane too as MAPP is way too hot, I rarely ever work on anything bigger than 28mm. Never experienced the LA-CO go black either, maybe it does that if you use MAPP???
 
Maybe. Laco is very popular on here.

I've been using nothing but Mapp for years now. I can't remember when I swapped over from propane, but it must be +10 years.

If I use propane (pick up one of my lads torches) it does my head in. Takes too long to heat the joint! I know it's just seconds difference, but I guess it's what you know.

I've also burnt powerflow. Maybe it's time I bought a can of propane!!

EverFlux is bloody great. You'd have to be a fool to burn it. It will clean up oxidised copped no problem, and it lasts ages. However it does eat your skin. Which makes you wonder. What is it doing to my lungs as I inhale the fumes?
 
I tried just fluxing just the pipe off the back of this thread and didn't like it. Pipe and fittings for me, small amount on each, gently heat and apply solder from the back/underneath the fitting and it leaves a nice neat ring of solder. Let the solder set and wipe with a damp cloth.

We all have our own methods and we'll all most likely never change them!
 
Hmmm, reply to the original question.

Its a pity that the flux manufacturers dont put a small brush connected to the underside of the lid of the flux tub anymore, isnt it?

I use an old toothbrush that I keep in my tool box and use that

Or I use my flat end screwdriver

Or I use my finger (btw my fingers always go green when I am handling copper pipe with or without touching the flux!!!!)

Only use everflux ..15mm-42mm only ever flux pipe ..always use a brush ..very rarely get a leak & always looks neat ;-)

if you flux the pipe only when you insert it in the fitting tecnically your fluxing the fitting too ????????
 
Like this 2013-03-23 14.26.21.jpg
 
Of course but any excess flux will be pushed out of the fitting and not into the pipe.
Depends what your soldering as well if central heating or hot and cold it can be flushed but if gas then apply little as poss and allso depends what flux you use ie aggressive or nonI which do u use
 
I love the fact that we had a debate on this very simple topic than ran into several pages, so I started this poll on a seperate thread. We're now into page number 8 and counting!

It's a simple question, but it's one that every plumber will have an opinion on.

Its amazing wat you find in peoples house I once found a flue on a room sealed boiler that was on an outside wall but the flue went vertical in to the loft then on a 45 down through the eaves and poped out didnt take a picture but wish I had there was no obstructions not sure why they didnt go straight out the wall strange
 
I found one installation, where the customer had installed his own boiler, and luckilly not been able to get it to work.

He's used self tappers to screw the old flue to the new boiler (a Biasi boiler - nice).

Anyway I Riddor'd that one. Don't do that very often.
 
I switched to powerflow today. Been doing a bit of soldering outside on a portable workbench at a job as soldering in a cupboard was a night mare.
Anyway I found that being outside (which is very cold in the snow), laco was burning off before I even took the chill out of the pipe. Power flow on the other hand was my saving grace. Think ill keep the laco in the shed with the other rubbish I don't use!

Thinly with a brush on the pipe and fitting then give the pipe a bit of a twist in the fitting
 
On the pipe with the solder and twist as you insert to the joint as many have said, if your posh use a brush 🙂
 
All the soldering I did today - I just fluxed the pipe and no fittings fluxed at all. I was using yorkshire fittings though.
Not turned the water back on yet as finishing off tomorrow 🙂
Wish me luck!

All the soldering you did???? I ended up doing your job on my way home....
A day on site then a bath and shower on way home😱....cheers for the referral im knackered now🙂
 
Hehe I was on day-rate yesterday on a refurb, back there this afternoon too, I just wouldn't of had time to do that other job, glad you sorted it mate 😉
 
Just flux on pipe but both pipe and fitting need to be cleaned with abrasive strip then push in and twist.
 
back to basics, surely the point is to use a small paint brush, clean the pipe and fitting with wire wool, i use the wire brushes to clean the fittings then apply a little flux, and the important point is to not use too much solder and to move the flame, ive seem fittings burnt black by too powerful a flame and the plumber not moving it to help the solder run around fully, im also old school and dont like to see solder snots hanging from the fittings
 
The same one as me by the sounds of it!

Wire wool can break up & leave small pieces of the metal on the pipe causing problems with the solder taking properly!!

Small strands of wool get left in the joint, over time these corrode and you get leaks..........simples 🙂
Or have you too much experience ?
 
been using wirewool for more than 30years, never had any issues, but its nice to see you have, i check my pipe before i insert it into the fitting.

You mean you have never noticed any issues. As well as the potential for leaving contaminants on the pipe if you use it near sanitary ware it can leave rust marks after a few hours.

Am I reading this correctly?

you use wire wool instead of a flux brush to apply flux? Or am I mis-reading this 🙂
 
sounds like you have made a lot of mistakes in your time, rust marks on sanitary ware? my advise is to take more care m8!

The only people I have ever met who reckon they have never made a mistake have been liars. I expect your one of those plumbers that has never had a leak as well.

Where do you get the lots of mistakes bit anyway? I've got rust marks on a bath once in 32 years and that is lots of mistakes? By the way I object to being called mate by someone as sanctimonious as you.

P.S. Do you want to buy a shift key?

it would be nice if before making a comment about a reply to thread that you check out the previous comments and catch up 1st, otherwise you have no idea whats going on and your looking for a free history lesson which i dont have time for
 
ok ive never had a leak before lol, i can turn water in wine, float like a butterfly and sting like a bee, take it easy and wind your neck in, if you dont like wire wool because you damaged a bath before thats ok, but im sure im not the only old school plumber that still uses it.
 
I say live and let live. I use emery cloth now, before that I used those expensive abrasive strips (the square mesh ones) and before that, many moons back, I used wire wool. With no problems. Just like thousands of other plumbers did or do.

I personally want to think that I'll never be too set in my ways to listen to advise....but I personally think live and let live.
 
I use steel wool from time to time and much prefer it to strips or sandpaper or fittings brushes or whatever. Everybody to there own thing. Much like 170 posts on how to flux a pipe. It is irrelevant.
 
Which is why it is irrelevant Danny. Anyone doing this for a living doesn't need told how to do the basics. Everyone will do it their own way.

Isnt it time we had another "how many wraps of ptfe do you use" thread?!
 
Everyone will do it the way that works best for them.

I've always fluxed both and Yorkshire fittings will back me up with that as that is what they recommend.
 
Last one i bought last year was about a fiver for a wee tin. Use it if you want really neat joints.

Never tried it, what's it like, I mean is it similar to LA-CO or is it white like... like that other one, forgot what it's called lol.

But how and why does it give neat joints? Never heard of it or seen it before.

It's brown and has the consistency of grease or Vaseline and indeed it is called Yorkshire flux.
It's still available and widely used for soldering electronic components.
 
I think its none cleaning, the fittings and pipe have to be rubbed bright and the exact correct amount of heat applied, doesnt snot like the self cleaning flux la-co etc
 
Its greeny brown colour. Not self cleaning so your fittings and pipe need to be spotless. The solder only runs where it is cleaned. Fry's fluxite and telux are similar. Smells lovely but nips worse than everflux in a cut. It has zinc chloride in it.
Btw you can make your own flux if you can be bothered. Throw a bit zinc in some spirits of salt and let it dissolve.

I always make sure my pipe and fittings are spotless before applying anyway so I'd hardly be having to change my habits, can't stand seeing people just fluxing a dirty pipe 'because the flux will clean it'. Does sound good this Yorkshire flux though.
 
Back in the day my tradesman used it for lubricating the o rings of soil pipe. How times have changed!
 
I went out to the shed and here are 2 different traditional ones for those who have never seen it. Frys and Telux both much the same as is Yorkshire.
I even sparked up the lamp for a wee sniff of the nostalgia Danny :smile:
