Hi,
I'm looking for a bit of advice on the best way to tackle a leaking joint between the gully and clay drain from the kitchen.
Bit of background first; this is an old Victorian house and still has the old cast iron downspout on the back which runs into a shallow cast in channel which in turn runs into the kitchen's gully along with the kitchen waste pipes. I had noticed that the concrete channel had suffered a bit of cracking and that the mortar flaunching around the grid had worn through in a couple places and it was looking like I'd need to cut out a few areas to make good with a bit of patch pointing.
One of those jobs you mean to get round to. Probably 6 months go by and I noticed that an area of the tarmaced path, parallel to the rainwater channel, had started to sink. I've heard the horror stories about subsidence caused by these things washing the subsoil away over time, so I decided to get on with the repair. Started knocking out the broken bits and found that sure enough there was a void below and decided to dig this out to expose the full extent of the problem. Fortunately it isn't too bad and is mostly around the gully pot. I figured two or three bags of limestone down there to fill up the voids and then make a new concrete surround to the gully and redo the affected areas of tarmac. At this point I was assuming that this had all been done but just rainwater getting through the cracks.
However, as I started digging out the loose stuff I started to get some nasty smelling black stuff out from around the gully, so suspected I was also getting stuff leaking from the kitchen waste. After chucking a bucket of water down the gully I could see that it was leaking at the joint between the gully outlet and the clay drain pipe.
I've exposed this as best I can, as can be seen in the photo and I've had a good feel all round the pipe and gully outlet and I can't feel or see any obvious cracks or damage.
It just seems to be that the joint has failed, so I'm hoping that there is some kind of product that I can repair this with rather than having to remove the pipe.
Having had a quick look online I'm wondering if this 2 pack epoxy putty would be right for the job?

Sounds like it might be the right tool for the job, I figure I can just stem it back into the joint all round the pipe, but I don't have any experience with drainage, so I'm open to advice on if I'm going to be going about this in the right way.
Cheers,
Dan
