Hi,
I'm doing some work on my kitchen, and want to install a gas hob.
Very close to where I want the gas hob, there is an unidentified 15mm copper pipe that pops out of the floor and is capped with a compression end-stop. Does anyone know how I can safely identify what's in it? The pipe is miles away from the sink and any hot/cold running water, it's also nowhere near any of the known routes for the water supply. There's only one pipe, so it's probably not the location of a long-gone, capped-off radiator. Also the temperature of the pipe is always at room temperature - again, this suggests it's nothing to do with the heating.
My current plan is to loosen the compression cap, and the moment I smell gas, tighten it back up again. If my guess is correct, then this will prove it's a gas pipe. If my guess is incorrect, then my fear is I'll be left with open pipe gushing gallons of water all over the house. Is there a better way of identifying what's in it?
If this pipe is NOT a gas pipe, then I'll need to get an engineer to tap into the supply to the gas boiler (on the opposite side of the kitchen), and run a pipe around three walls of the kitchen - this will involve removing ALL the kitchen units - something I'm anxious to avoid.
Thanks
