flux brush after soldering

[Mgrant]

Do many people use a flux brush to wipe fittings just after.soldering to help the solder run around the fitting?

 

[GasmanxxxR1]

Hate that, my mate does it and it drives me wild!

 

[GasmanxxxR1]

But, I am a picky bas**rd

 

[newcastle phill]

Nope. Just dip the solder in the flux if needed. Wipe with wet rag once cool

 

[Best]

I just keep dipping the solder wire in flux and adding it to the joint as I heat it

My mate does it too. Paints the pipe with flux! Hate it!

 

[Chalked]

If you don't overheat the joint and use a quality flux. You shoudnt need to add more flux.

That's an old BG trick.

 

[1Steven]

I just remembered that a chap I worked with last year used to solder his joints that way. I kid you not!

 

[lame plumber]

waste of flux

 

[Mgrant]

Thought the technic was.used.to help make sure solder.had.run all the way around?

 

[1Steven]

Chap did not put any solder in the joint though only on the outside.

The chance of getting leaks must be very high

no as the solder should of already run/ entered the joint

 

[1Steven]

Watched him do it a few times on his jobs and blow me not one leak. Have not tried it myself.

But can't hold a lot pressure can it ?

 

[1Steven]

Yes it does hold pressure, wish I had filmed him doing now. Could have gone plumbum viral :stuart:

No,i am a proper plumber i use my fingers,flux the pipe,assemble,solder,wipe with wool or a dry rag,wet rag when cool

 

[1Steven]

Bet you know when you have a cut on your finger!

dont notice now TBH

 

[c.gas]

I used to do that when I first started just to be on the safe side, but soon realised that it was pointless

 

[plumben]

I'm with gas man on this, I use my finger, flux the pipe, push all the fittings together and whipe the excess off and stick it back in the tub

 

[Stigster]

I can't stand this. It seems like a way to "polish" up what is in fact just bad technique. A side effect is that the flux brush ends up disintegrating with the hot brushing and all the bits end up in the flux pot like loads of dead midges.

It grinds my gears when I see students doing it.

 

[Stanios]

Flux oxidises copper so unless you wash your fittings afterwards they will all go green the next day.

 

[tamz]

I'll be honest. That one gets on my wick if i see it, usually followed by a mouth full of abuse depending what kinda mood i'm in.

And what if your in a bad mood - physical violence ??? [emoji12]

 

[tamz]

[tommy1712]

I don't use a brush just use the solder to apply

the way I was taught nearly 30 years ago.. never fails to give a good joint and still do it that way now but talking to younger guys they use cleaning fluxes etc and wipe with flux brush afterwards but I dont see the point, as someone said, waste of flux.
I have modernised my technique with the use of a 1/2" paintbrush to get the flux on
