Will be cuuting out some pipe work in cold feed area of central heating system due to partial blockages. I have thought about using 22 mm slip couplers to ease reassembly. How should you keep the slip coupler in place on a vertical section prior to soldering ?
How to fit a 22mm slip coupler

you will need to cut the correct length of pipe out, and fit the coupler first (without soldering) to make sure it is the right fit. Then wire wool up the end of the pipes and inside of the fittings, flux the end of pipe and inside of the fittings, then solder until you see a silver ring around both joints. Then allow to cool for a few mins before removing any excess flux and marks. That's the way I'd do it anyway!!
thanks for prompt response. My concern is holding the coupler in place as with a standard coupler there is a ridge in the middle which will hold the coupler in place
i don't understand? hold it in place? what for??!!! sorry if i sound stupid..
A slip coupler "slips" up and down the pipe so on a vertical section it will slip down the pipe while trying to solder - I guess
i'm not sure about these. surely there must be some kind of stop in them for the pipes to sit. i'd much rather just use another bit of copper pipe and 2 straight connector's personally!!!
NO STOP IN A SLIP SOCKRT, That'S Why it's called a slip.
Stevehayes is obviously not a plumber, or at best fresh out of a 10week CC course
Never put flux in the fitting.
Normally you can prop the fitting up with a bit of copper tube, or if its clip distance from the wall you can wedge something behind it
So any thoughts on holding in place on a vertical run prior to soldering
I disagree with doitall. I think fluxing the isnide of the fitting lightly as well as the end of the pipe helps the solder soldify better. Otherwise you may need to use more solder and have a messy ugly looking joint!! It's all about personal choice but fluxing both works best for me. never had a leaky joint.
And i concur with doitall , you are definetly NOT A PLUMBER when you do not understand the fundamentals of soldered joint preparation!! WTF sort of word is solderize????
Keith.
I meant soldify not solderize!
Anyway what I'm saying is when I make an end feed solder joint, I use wire wool to clean both the outside of the pipe and the inside of the fitting. Then I use flux and brush it around the outside of pipe and also a little bit inside the fitting. Then I heat my blowtorch, aim it at the joint, then after 30 or do seconds touch the solder onto the joint until it runs. When I am happy it is complete I leave it to cool down before removing any excess flux, marks using a damp cloth. It has always worked well for me this way.

Steve i would quit while you are only slightly behind not even knowing what a slip socket is .
Not only have I got my question answered but I have received some soldering advice
Many thanks
