How to fit a 22mm slip coupler

I do know what they are, never used one though. I'd prefer to use a proper piece of copper pipe and solder it in place using straight connector joints. Much better looking on the eye!
 
Now you really are sounding silly a slip socket looks exactly the same as a normal socket.. also how would you clean the excess flux from inside the pipe after soldering
 
inside the pipe? clean the excess flux that was on the outside of the pipe after soldering is what i said (meant)! after soldering i always flush my system through/let the water run for a bit before using it.

Slip couplings don't look exactly the same, plus as mentioned before are trickier to solder/keep in place.

If you measure the pipe correctly (x-dimesnsions taken into account) then you can use 2 straight connectors between the new piece of pipe and previous pipe/s. Easier as they stay in place while soldering. That's my persoanl choice anyway.
 
Both ends are fixed, "Now what"

You do should not flux inside the fitting it doesn't need it.

How do you flush gas pipes.

And if I stand an slip socket next to an normal socket you could note tell the difference
 
Do a little search on net and look at a 22mm socket and a 22mm slip socket other than a line in the middle they are exactly the same.
 
ok fair enough different terms. I called them straight connectors, not coupling, I was thinking of something slightly different.

But come on, we all have different ways and I prefer to add a little flux inside the fitting (only to where the pipe will sit). It helps me get a better join.

And obviously you do not flush gas pipes, as you do not need to! I only flush water pipes as I don't want to be drinking straight after connection without flushing-I don't wanna drink flux and water!!! :)
 
flux that has been put into a fitting is pushed out of fitting by the pipe melts and runs down inside of pipe and causes blockages in gas pipes also water does not wash it away for a long time
 
i've never had any problems (touch wood)! thanks for the advice though.

but really what's the difference between fluxing the outisde of the pipe (which goes in to the fitting anyway and spreads around in there) and putting a bit of flux in the fitting where the pipe is going to sit!! it just the same really! i only do it out of habit.
 
Thats the point, it is not the same. if you flux inside the fitting when you push the pipe together the flux is pushed into the inside of the pipe.

Bad news especially for gas
 
Ok, thanks for your advice. Will not flux inside the fitting next time I solder. Never thought of it being a problem like that before! I was just making extra sure the soler would be fully watertight I suppose!
 
Okay, tell me if this shouldn't be done and I wont take effence but I was always taught to stop a soldered fitting from slipping (or turning in the case of elbows) to create a small dimple where the fittings going to sit with a small screwdriver, doesnt take much to hold fitting in place. Is this not acceptable to keep a fitting in place prior to soldering? Ive always tried it with success...
