What is a black pipe BS1972 we have found 4 inches below ground in our garden?

How old is the house ?
Approx what direction is the pipe running i.e. to or from the house ?

At that sort of depth it is unlikely to be mains water as it would be subject to freezing.

Could be an old temporary supply for the building site is house in not that old.

Our house is around 1950’s but we think the strip of land that the pipe is on, didn’t use to be part of the land of the house and maybe was used when they built the 30 odd house down the road that runs the other side of our house...so maybe? Hoping it is an old disused pipe/cable. Will cut a hole to see

If it doesn't look like it is running to/from your house then chances are it is an old temporary water supply. If it was a live mains supply it should be a minimum of 750mm below ground for frost protection.

If it is under pressure you won't get the cap on.
I would nick the top of the pipe with a hacksaw but after you have put a jubilee clip loosely on the pipe close by & find a piece of rubber such as bike inner tube to slide under it if water comes out. Then tighten it down onto the cut to stop the flow.

Depends on the pressure

Depends on how strong your arms are but nick & clip with rubber wins ever time (& nothing sexual about that just read my previous post)

This is ALKATHENE pipe for cold water . I have this pipe half inch for my water supply . Being imperial size and plastic. What could be used for a stop valve on it. It is easy accessible under my foundation.
