Mystery pipe

[puddycat]

Hi, I am currently fitting an ensuite to my bedroom and am running a waste pipe along the floor joints to the toilet, but on lifting the floor, I have found a 35mm black rubber pipe. Its running at right angles to the direction I am going, and I have no idea what it was ever used for. I live in a black of flats that was once a hotel and before that it was very large family home, so although the pipe seems to start from what is now a single bedroom, who knows what the room was originally used for. I don't want to rip the whole floor up,but I dont want t cut into the pipe until I know whats inside it either.........any advice?

Thank you

Don't cut it incase it is a heavy electric cable!
Or you could lose all your nine lives.

Let sleeping pipes lie then???

Is it rubber, or is it a soft plastic pipe? Could have been a waste or overflow pipe, but I still would worry about it being a duct pipe full of electric cables.

You won't need to lift all the floorboards, just take out a floorboard section every 4-5 floorboards or so to find its source. You've done the right by not cutting it. Like any pipe or electrical cable that I am going to have to cut in to I want to know 110% that the power is isolated or the pipe is empty. It sounds like the building has gone through a lot of changes in its time and with out brig confident you know what it is I don't think you really have choice but track down the origins of it.
