I am currently renovating my house and have just had the kitchen plastered. After removing the cabinets I found this under one and am looking for any advice as to what it may be and options in regard to removal etc.
I'm assuming it's gas so haven't touched it / tried to open as it's quite stiff and don't want to find it won't close if it is.
Edit The house is in the UK, a 1950s 2 bedroom semi detached ex-council house. It is build on a solid concrete foundation so I'm assuming this pipework is an original but have no idea what it is from.
