Possibly leaking waste pipe

[nas7001]

Hi,
I have just noticed that 2 cracks coming from the pipe are getting worse. I believe it is leaking but I am not 100% sure. Also if it is, will digging up the concrete damage the house in any way as the pipe is quite close to the wall. Also will a chisel be sufficient?

Thanks.

The cracks may just be movement due to the paths not having any real foundations......if that is a cast iron pipe I would carefully expose where it enters the concrete and disturb it as little as possible.....its not necessarily leaking.
You'll probably find the pipe enters a salt glaze junction, and then heads for a nearby manhole. Salt glaze pipes are very fragile, so go carefully!

Hi,
The pipe is fully plastic and I have lifted up the manhole cover in my garden and can see the pipe continues and enters into the sewer.

Are the underground drains plastic? If so then unlikely to be a leak, but if the plastic stack has replaced an earlier cast pipe then as John has said, it could well be leaking on the joint where the plastic joins the clay pipe underground.

May need slightly more than a chisel to break that concrete out, once you've got through it, use your chisel to break the last bit away from the walls.
