Advice on lifting this slab to see if manhole was covered

[Ivor Windybottom]

If it's your own pipework you can do whatever the heck you like with it, rip it all out and start again if you like, as is often the best way with old houses anyway, as most of it is probably cracked and leaking.

If it serves the neighbourhood you can't do much with it without permission.

If the shared sewer is at the front then you're very fortunate.

Perhaps start from your kitchen and bathroom, work out how they get to that shared sewer.

Anyway I went down a couple of inches and it's solid.

Using a drill? Any metal swarf, on the tip of the drill?

Keep going, without smashing the hell out of it.
Many layers may have been added in the years.

I didn't use a drill I can give that a try. Hope I don't hit a pipe though. I imagine the drain would be v deep. Thanks

There's no evidence of there being a drain there, in fact the evidence says it's NOT there!

This is all just a hunch because two rectangular slabs were included in the crazy paving, you're now tunneling to the centre of the earth to find a pipe that you already know isn't there.

Start with what you DO know, the positions of your kitchen, bathroom and gutter downpipes. Follow those pipes, find out where they go - they will lead you to victory instead of smashing random holes based on an imaginary hunch.

I think you are spot on in what you say. I do know having opened up my inspection chambers down an alley far from the slabs that the waste runs to the front of the house not to the sewage pipe that runs across the back of my property that is touching the extension from Thames water plans.

I know the neighbour has an inspection chamber in their conservatory and the waste runs to where the Thames water plan shows.

I just wanted to understand if I could add to my extension to the side of would their be more cost of an IC was found and indeed the sewer pipe is sitting touching my foundation and also in the way for the future.

Might your rain water run to one, and your grey/soil go to the other? One at the front, one at the rear. Ours is separate, two pipes at the rear.
