flux brush after soldering

[Old Account]

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 ?

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

dont notice now TBH

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

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.

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.

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
