fluxing pipework and fittings prior to soldering

[atty17]

ok no major issue here but I was taught when fluxing joints only to flux the pipe and not the fitting, the reason is that if the inner of the end feed joint is fluxed then when the pipe is inserted into the fitting then excess flux is pushed into the pipework.
thoughts either way on this?

i was taught to just flux pipe also. never had a leak from any doing it that way.

 

[PlumbBobBob]

sounds about right to me. i only flux the pipe.

 

[tamz]

I flux fitting and pipe but never use active flux.
Even if you only flux the pipe it will still get inside the pipe as it melts.

nothing wrong with a very small amount on the inside of the fitting if your unsure about things and your flushing straight away. even just putting it on the pipe alone get flux inside the pipework i think its more important that as little as possible flux is used, better to clean and not be lazy to avoid using too much.

One more for the pipe only.

 

[glenno1]

Pipe only but it will get inside

 

[hammers4spanner]

pipe is correct way but im either or , i also use my finger and when short of mayo then i use flux for my sarnies

 

[AWheating]

what flux?

 

[Guest123]

Yorkshire's instructions for their soldered fittings are to flux both the pipe and the fitting and twist it clockwise when inserting the pipe to ensure equal distribution of the flux without pushing it all into the fitting.

I flux pipe and fitting. Everyone has their own preference and you should just do what works best for you.

particularly for the gas pipe work I was taught to only flux the pipe as any flux inside the pipe/fitting will stay there.
for water pipes they will be flushed so that's less of an issue

That's the standard installation kit for flexy installers.

One more for pipe & fitting.

 

[plumbojumbo]

we were taught to clean and flux pipe and fitting at college :book:

 

[Resolute]

I was taught to flux the pipe. However sometimes I'll do the fitting if I'm soldering close to a wall or something and can't easily get all the way round the pipe.

 

[Phil]

Fitting & pipe.

I apply to pipe first and clean the brush on the fitting.

 

[Rickster123]

Always the fitting for me. Just the way I've always done it. To be honest the correct way is which ever doesn't leak when you fill up!

 

[Best]

Pipe & fitting for me. Just a thin smear in fitting though. That's the way I was told & it's hard to change.
Probably wise to keep adding a bit of flux on the solder wire as you are soldering.
I use Fluxite or Yorkshire Traditional grease based flux as they are excellent every way & not pure acid, like some.

 

[REDSAW]

no system, you dont need to flux push fit's.

i can flux 5-6 joints without re dipping my brush, in fact i am on the same 120gram laco pot bought 3 years ago, only filled it twice.

Me too. Apply a thin smear with a blob on end of my solder. Always worked for me.

Wire wool on both pipe & fitting.
Light smear of flux on both.
Small blob of flux on solder.

No leaks!

Can't believe I wasted all that time/flux by doing both! :fuk2:

Do you lot clean your fittings & pipe or just flux dirrty?

"flux dirrty" ? Sounds rude, so wouldn't admit to it! Lol!
No, - I always clean every part well that is to be soldered. I use Fluxite which is not too strong, so better to clean all copper, especially dirty Yorkshires or tarnished/old pipes. I first use cloth emery on any glazed or dirty pipe or fittings, then wire wool. End feed are the best fittings to solder IMO & are usually fairly clean when you buy them.

I've seen people pulled up on fluxing fittings whilst doing CCN1. I was taught fitting only as any excess gets pushed out where you can wipe it off before soldering. Fluxing the fitting allows excess to be pushed into the pipe where it can cause corrosion and allow excess solder to be pulled into the pipe restricting the flow and/or creating those annoying little balls of solder which you find jingling around inside heating pumps.
