What do I need to blank this off. (Waste pipe T)

[bigdrew]

Whats the easiest way for me to remove this and black it off?.

I'm assuming its solvent welded.
Would this be what I need: http://www.screwfix.com/p/floplast-abs-access-plugs-white-32mm-5-pack/87263

OD of the grey bit is 48mm
OD of the black is 36

I'm assuming it is all based around Ø32 pipe?

Cut the black pipe about 2" to the left of the stack and :

the boss branch you have there is pushfit.

The rest of the pipe is solvent welded.. Is it possible that the first join is push fit and the rest welded? - I thought I had read they weren't compatible

 

[JimCrow]

where the black pipe enters the branch is a ring seal joint, twist the pipe out then push in the access plug in your link.

I'd carefully cut the pipe and fit a socket and cap, as in newboy's link.

Pulling that black pipe out from the boss risks disturbing the o ring in the boss, and I have major doubts you'll get it to seal again around the new plug.

I did wonder about that.. Its not moved for 20+ years

Could I just replace the 0 ring as well? Is it one of these?

If its not possible to replace the o ring I'll cut the pipe..

No it's an old Marley one. I'd leave it alone as well.

 

[bigdrew]

Thanks very much; I'll leave the pipe in and do as Newboy suggested.

I'd go so far as to get a MacAlpine universal coupling and put the access plug in that and the black "bastard size " Marley in the other end . I'm sure that stuff wasn't compatible with any other solvent weld - back in the day - I do know it was a thick wall pipe.

Is the actual soil pipe a standard fit.. Could I replace it with this http://www.screwfix.com/p/floplast-sp190-92-5-branch-black-110mm/29610 with a fairly high chance of it not leaking at least I'll have a standard 32mm output then!

Space is at a bit of a premium so it would be good to box it of as close as possible!

Assuming I can move it around enough to shimmy it apart and out!

 

[Nige F]

Plastic Soil has always been standard . If you've got a set of callipers ( or something similar) you could check the Marley waste O.D. my memory might be inaccurate. You'd have to cut the soil pipe and insert a short length under your new fitting and join with a slip coupling - unless you can get the pipe to move up+down.

Ha, thats good to hear!. I was starting to to get the impression I'd never hear the word 'standard'..
