Clay pipe in foundation wall?

[AMS1]

Hello

Please could you shed some light on this ... a week ago we took up a couple of floorboards in our front room to take a look at the gas pipe beneath (to see where it ran). Unfortunately there seemed to be pooling of water in the floor beneath.

An Environmental Health officer came out, tested it, and pronounced it as sewage. There wasn't a lot of it, and it has since dried up and so far *crosses fingers* hasn't returned, but it is troubling to wonder where it came from.

We unblocked the main drain at the side of the house (it was seriously blocked) and we're hoping that in doing so we've rectified whatever problem that may have caused this, but we've no way of being certain.

What's puzzling our OH and myself is that in the foundation wall beneath that room (this wall is internal and is part of our kitchen wall also) is what seems to be a clay pipe, about 10-12cm in diameter. It doesn't go anywhere, it seems to be cut off at the wall, so that it's almost flush with it.

Does anyone have any ideas as to what it's for? We're wondering if it's linked to the sewage water getting into a house.

The house was built by the council, modernised in the 1970s, and is over 70 years old.

Thank you.

Possibly being used as a vent.

That's what we wondered - do you have any ideas - if this were the case - where this pipe would come out?

You will need to post pictures of the pipe and fix the leaking sewage pipe, it would be the same pipe?

It sounds to me like a conduit.

We often use 110mm pipe to duct leccy, gas, water etc through walls and found's.

Have a root around and see if there is owt running through...

Thank you for your replies.

A chap from the water company came out yesterday to look at the main drain at the side of the house and has found tree roots in the pipes so he's ordering camera work to investigate.

We showed him the pipe in the foundation wall, and he's said that as a gesture of goodwill he'll tell the camera guys to stick the camera into that pipe too when they're here even though technically it's not the water company's responsibility, to see what it is.
