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
