    Hi all

    We're having a small hallway extension built on the front of our property, I've dug and laid the foundations as per the picture (building control have signed off)... but this pipe is majorly in the way. LABC won't comment on what it is, the builder is unsure...

    Our electric is fed over-head by cables that run on the front of the house so I think I can rule that out. The stopcock for water is in the kitchen at the back of the house and the pipe "seems" to bend in the wrong direction at the bottom. Gas comes in on the side of the house.

    I've used an inspection camera attached to a drain rod and it runs through our dining room at the front through the wall into the kitchen where I can't follow it any further as there is a wall in the way.

    With it being so close to the surface I would hope its no longer in use, however, no-one can confirm what it is... is there anyone I can ring?! The house was built in 1910.

    It seems to be a metal pipe with some brittle black coating. Inside under the floorboards its coated in some form of lagging, all be it only a thin sheath, with the black stuff beneath it.

    Any help would be appreciated...

    Being lagged may suggest water, turn o mains water and put a screwdriver on the pipe and rest an ear onto the screwdriver will hear the water running through the pipe by doing this.:)

    sorry i couldn't make out the pipe from the first picture that looks like an old water pipe you can see where it branches off to the neighbours but has been capped off in the days when your house was built property's shared a water main and one stop tap.. run the cold tap on full and put your ear to the pipe to see if you can hear water running also where is the stop tap in the street is it inline with the pipe..

    I'll try thay this morning and report back, thanks peeps.

    You'd never believe it but we dont have individual stop taps on the street, you get one put in on the drive if you opt for a meter, otherwise I suppose its half the street?

    Scratch off the black on pipe & see if it's lead or iron,I reckon that is a old water pipe.

    does he know any other trades people ?

    He does! But sadly he isn't local so not sure anyone will be willing to do an hours drive to have a look.

    Attracted some odd looks from the neighbours this morning holding a screwdriver to the pipe, with the tap running, couldn't hear a thing. Scratched off to reveal some shiny metal as below, so assume its lead.

    Anglian have installed a hole on the drive when it was tarmac'd (we share a drive with a housing association Tennant), which is empty (highlighted in red below). I might risk drilling a 1mm hole in the pipe and see what happens... just hope its not gas...

    The water pipe does not necessarily need to be lead, although that by far was the most common, iron/barrel pipes were also used for water supplies into houses.
    Put a magnet on the pipe, if it sticks it is iron, if it does not stick it is lead.
    I would not start drilling holes in it though, what are you going to do if water or gas gush out.

    Around here you can have a meter installed and if you change your mind within 1 year they will take it back out
    Doesn't help with your immediate issue, just food for thought

    tbh,when that unknown item was originally discovered before laying the foundation. Some consideration of moving the foundation to the left a couple if inches to avoid most of the unknown item and protect the unknown item where it passes through new block or brick with a duct or conduit.
    Or spend some more cash and get other trades in to further investigate the unknown item !

    Yes, my lack of foresight let me down dearly in this case.

    Anglian is coming out Monday to ***** for fitting a meter, so I'll see what they say.

    Cheers guys

    There are two pipes; The one in question and one at 90 degrees which looks like it has been capped

    Even if Anglian fit a water meter, how is that going to help detect the purpose of the pipe as it could be branched anywhere from the meter installation ?

    Like the house I have at the moment there may have been an historic problem with the mains supply so it was capped off inside the house and then a new connection was run. So you could still cut the pipe and water / gas come out.

    Tracing the pipes is quite easy especially since it is a metal pipe, all you have to do is hire one of these

    TBH the fact your builder went ahead and poured the founds without resolving the pipe runs doesn't inspire confidence as it is basic good practice.
