upstairs bathroom existing soil pipe alteration advice

[Tirglas_7]

Hi

continuing with my 80's dormer renovations i'm now doing the upstairs bathroom.

the soil pipe is internal to the house that exits out of the roof, i now want to move the toliet location over by approx 600mm then frame out from the block wall, the plan is then to erect a stud wall outwards which will then give me an area for the shower cubicle one side and a place to install a rad the other (wall space is limited).





my paint skills aren't great, but hopefully from the pic you get the idea. hows best to actually adjust the soil pipe? should i just cut it before the joint and angled section? or is there a way of breaking/reusing the joint? i think its all solvent welded. or are there any other methods??

the rest of the waste pipes will need to exit through the wall into the next room then run along and back into the soil pipe at this location. as you can see the previous connection has fractured, what is the best way to recover this? can i just clean up the edges then solvent weld a new one on??





many thanks for your time

That existing soil,tee system is very bad and maybe why it has leaked.

best consider getting an approved plumber in to sort out the pipes and issue a certificate of tested compliance .useful when you come to sell or start an insurance claim.

seen worse thou !

trust me we wont be moving again.

so the only way to sort it is to replace that tee completely? what is the problem with the design?

also why do i need a plumber in to do it?

many thanks

You could chop the soil pipe and add in 600mm with a solvent or pushfit socket. My paint skills are excellent so first try and pull the pan connector off, if it's stuck cut it here:

The connection into the side of the T is a bodge. There is a T with an adaptor on the side or you could replace the T and fit a strap on boss above or below it.

also why do i need a plumber in to do it?

An approved plumber will be able to certify and issue paperwork to prove the alteration is to the acceptable current standards and has been tested.

or there is the diy route,which i see most days omfg

Where the waste is (was) connected in to the soil pipe, the fitting on the end of the waste pipe is a boss adaptor which should be glued in to a pre-formed boss on the branch. Yours has been glued in to a hole cut in the side of the branch, no good at all. I would now describe that branch as scrap. If you cut the soil above the branch and pull the branch out you can then fit a new branch with bosses. You could also get the waste pipe lower to suit the shower tray.

Great many thanks for all the replies.

I'll replace the tee then, and if im doing that I might as well replace the piece running to the toilet with one new piece.

The pipe exits a flat roof above which I've just had renewed with epdm, i really dont want to compromise the seal on that.I take it to get the old tee out and the new one in, either the remaining top part needs to go up or the bottom needs to go down?

Thanks again for all the replies

 

[Daveydub]

either the remaining top part needs to go up

You can get a slip socket (or grind the stops out of an ordinary push-fit socket). This will slide all the way on to 1 section, then line up the other section and slide to be half & half. I usually fit a clip below to make sure it can not slide down. Also handy to get a clip to support so that it is not just hanging from the roofing. Felt tip and gaffer tape is handy to make sure that the top section remains at the correct height. If desperate you can use 2 slip sockets then you do not need any give on the pipes at all. If that doesn't make sense let me know and i will find a better way of explaining.

Yes I understand, I'll have a read up on slip sockets.

Thanks again
