Gas pipes within plaster on wall

[dulciepreston]

Hi,
I live in an 1890’s house with an exposed gable end wall which appears to suffer from damp at about cill level to the left and right of a window. Damp has caused the plaster to blow at a few locations and you can hear by further tapping that some other locations remain live. I was also experiencing a brown mark continually appearing through the plaster so today I decided to address the problem. I chipped off all the loose plaster at cill level and below the window and also removed the radiator to get at everywhere else likely to be a problem. On both sides of the window I exposed a 10mm dia (appx) pipe running from floor level to 6’ up the wall which was buried in the plaster. The slightly damp wall over the years has caused this pipe to rust and brown marks have leached through the plaster work all along its length. I’m guessing that this pipe is an old gas supply pipe which I will need to deal with prior to progressing with the plaster repair.
Firstly, is this pipe likely to be live or can it be just sawn off at skirting level, or will it need to be capped off at skirting level by a gas man.

thanks in advance,

Chances are as you say it's an old part of the house carcase for lighting. Wow two lights in the one room must have been quite upmarket for the time!

Fair chance they are still connected most were just plugged and sometimes the elbow turned back into the wall.

Get a gas safe engineer to cut off and cap them under the floor, if possible strip them back as far as they can I doubt you will be using them again! Then you can rip them out of the wall and be rust free.

PS would be great if they made a comeback, (insurance companies would have a fit though!) gas light is a really nice soft light, I had them in my first house and fitted an outside gas lamp at my last place

Try and trace the pipe back, you say it finishes about 6 ft from floor level, is it capped off there ??

going by the diameter of the pipe I reckon it could be an old Gas lighting pipe.

You could lift the floorboards and see what the pipe does under the floor!

Most lights were supplied upwards from under the floor.

Technically all old gas pipes should still be plugged and made gas tight!
