I dug a test hole today to prep for some work later in the year (drain depth etc.)
However I stumbled upon a few other pipes in the process...
The brown pipe is the clay foul drain I was looking for.
There is a silver metal pipe in the top of the image - this had roughly a 32mm OD.
There is black plastic pipe to the right of the image - this had roughly 25mm OD.
Its unlikely these are water unless they're old and disused as I know where the water pipe runs and it's 1m away.
I have a feeling they are the gas pipe(silver)and a ducted electrical cable feeding the garage(black). Are older gas pipes typically metal? House is 30s build.
Extra info which may or may not go against my 'theory':
-The black pipe is running directly towards the location where a 34mm OD (black) gas pipe comes out the ground into the meter. This goes against my theory.
-The black pipe is also in line with where the electric cable comes out of the ground in the garage. This supports my theory and it may just run into the house at a similar point to the gas main coming out of the ground.
-There would be no purpose for the silver pipe to run right to left. This would not intersect with my house or garage, it would run from neighbours garden to neighbours garden. If it is not the gas pipe I have literally no idea what it could be!? potentially an old & disused water main? I expect it could be part of a large radius bend in the gas pipe (so it appears straight).
