I wanted to replace a gully that is taking rainwater from the garage roof, and so that I can also tap in with a channel drain from a patio that I'm building.
The drain pipe is made from clay and it appears that part where gully is connected to the main pipe is cemented in (wtf)
Can anyone suggest what and how to tackle this.
I have tried to chisel out the cement a bit and managed to do it to the point of what I suspect is a beginning of a joint.
Then I have tried to chisel out the cement on the joining pipe but after going in around 10mm deep I gave in as I did not want to damage anything.
I'm considering hiring a man as I'm simply scared
Any suggestions welcome
On old clay drainage the spigot goes into the collar, a black yarn is inserted around the spigot and tapped in tight, then mortar is packed in to the collar and smoothed off and haunched. That made the pipe watertight. It was very labour intensive back in the day, we didn't have the luxury of push fit then. Cut it off to the right of that collar and buy a clay to plastic adaptor from one of the sheds, replace gully with a plassy one.
Correct, angle grinder will be fine. You might need do several cuts to get you cutter in then tidy it up after. After you get pipe out can you smash at collar to confirm the yarn in there, just for curiosity, see if was done right :;):

sorry for late reply.
so managed to get it all done.
what I found was that under the cement there was another clay pipe about 10-15cm long conected to the part that i initially exposed. and to that bit there was a 90* clay bend. all cemented together
