Detached Exit Pipe - Need new part?

[fusional]

Hi, hope someone can help!

So the main pipe which runs down the side of our building taking water from our flat and the flat below's bathroom seems to have come loose from where it meets the ground floor flat. Photo hopefully shows this. All bathroom water is going onto the roof of the garden flat below. Not nice.

I can't see any part that has fallen off - but the pipe does seem an inch or two short. Right now all I have is leak-sealing tape and gaffer tape. Is there a part I need to buy or how else can I fix this?

Welcome to the forum. That rubber slip coupling where the 2 pipes join should be half & half on both pipes then tighten the jubilee clips so it looks like something has come loose and moved.

Thanks for the quick reply - so I should be able to just pull down the pipe and then fasten?

I did try to yank it down a bit but there wasn't a lot of give - but I'll try again.

Don`t go yanking anything! You have to find out if a pipe has slipped down or is it the rubber coupling that has slipped down.

Either the upper pipe was cut too short
Or the upper pipe has crept up with thermal movement
or the lower pipe has dropped.

Check in the flat below to see if the lower pipe has dropped

In the worst case if the gap is too big and wont close, you'll need another Marley coupler and a short piece of pipe.
Cut a piece of the existing out and then cut a new piece to fit exactly in the gap.
You'll need a coupler at both ends of the new piece.

Ok, thanks. Well the pipe at the bottom meets the ground floor roof just below - so that can't haev shifted - and don't understand how the upper pipe could/would have shifted upwards - so I think it must have been the rubber coupling.

Sorry - one more question - if I shift the rubbber coupling up, how do I fix it in place? That jubilee clip doesn't look like it is attached to the rubber coupling.

One more photo in case that helps.

Jubilee clips are metal on outside of the rubber coupling not the plastic clip below the coupling.
Looking again at the pictures the Marley coupling looks a lot newer than the pipes ????

I thought that was snow on the wall, then I realised..

On this photo the upper pipe looks like cast iron?
If so, cutting would not be a simple DIY job.

Just noticed the pipe clip is doing nothing so has the lower section dropped even though the OP said it hasn`t but the Marley coupling still has the paper on it so it`s not that old.
