[QUOTE 4167207, member: 9609"]Was the job done just get rid of the side junction or was it to get access to the copper pipe behind ?

Presumably you were able to lift the upper part of the pipe to slide the couplings on (or was there enough side ways bend) so why didn't you just replace the upper half to its next junction ?[/QUOTE]
I wanted to get rid of the redundant branch boss, and also to get to the copper pipe behind the soil pipe. There was no way of flexing the soil pipe up or down so cutting a vertical length out was by far the easiest option. Slip couplings enabled the new length of PVC pipe to go in without any flexing. Besides, I really wanted to avoid flexing because I had a vision of the old rubber seals above and below starting to weep. They are at least thirty five years old, and that's on the limit of their life expectancy.
Actually cutting the pipe only took about 10 minutes, including chamfering the spigots. The copper plumbing was painful, and sliding on the couplings took forever. Well it seemed like forever anyway.

[QUOTE 4167927, member: 9609"]With these 'slip couplings' can you slide them entirely over one pipe, then when insitu slide it so its half over each ?

All couplings I have ever used have a stop in the middle to make sure the pipe is centred and often have the seals angled so as they slip on but are reluctant to come off. that's why I was a little confused at what you were doing. And what are the jubilees gripping, or are they just there to stop the couplings ever moving?[/QUOTE]
Slip couplings have no pipe stop halfway down them. They are often called "repair couplings". You can slide them all the way up and down a pipe of any length if you slather them in enough silicone grease. I think they cost me about £4 each from Wickes.

Yes, the jubilee clips are just a way of stopping the fittings wandering off over time as the soil pipe moves due to themal expansion and contraction. A couple of stainless steel self-tappers would probably work as well but I didn't want to drill into the pipe.

[QUOTE 4167939, member: 9609"]good to know they exist, I would have probably faffed about for ages trying to cut the middle stop out, then damaged to one way seals.[/QUOTE]
Here's a clip I just found...

[/media]. I used really thick silicone grease, more like an engineering grease than a light aerosol spray. Also, I slid the coupler all the way onto the fixed lengths of pipe before sliding them back over the joint because I really didn't want to stress/bend the fixed pipes. Getting the seals over the ends of pipe when "going in the wrong direction" was an absolute nightmare, but it is possible. It's a mixture of twisting the fitting with a Boa rubber strap wrench and a lot of brute force.

Come on @Fnaar, do your thing!
