Leak from CHS mystery outdoor pipe

[ShaunCorbs]

do you have a outbuilding / garage ?

Bear with me - got floor up (girlfriend gonna love me doing this now...)

this is the internal view, so now you see the drain off on the left and the LIVE ELECTRICAL CABLE on the right. Good call on the safety reminder Harvest Fields!

Following from my previous post you're spot on Shaun - this must be the electrical feed for the garage - it'll run down the side of the house to the back and it's in line with the garage end of said cable I found while digging up the garden (thought at the time it wasn't running on the side I'd expected)

So, mystery cable is powering the garage and can't be the cause of the leaching water. Yet there's no sign of any other pipework leaving the house other than the drain off, which does not appear to be leaking at the valve. I'll try calling central heating and looking at internal pipework. What else could it be at this point!?

whats the piece of metal on the wall for?

Just tried scraping the crud off the surface and now I'm worried that it's rubber! That can't be right can it? Then again I have no idea why any sort of pipe/hose would be here in the first place!

That seems to me lead not rubber

I’d say it’s definately connected to your CH system

further left looks like old insulation (thinking this could be another pipe that doesn’t exit to outside) also may just be the picture but it looks damp below the pipes? The answer maybe a pipe leaking from inside

It's a right mess down there but you're right, it's generally damp to the touch where I can reach. No signs of leaks from any pipes I can see... but that would be too easy eh!

Seems to correlate with your drop of system pressure,try running the CH for hour or so an then inspecting the void you’ve opened up an alternatively check it with the system cold for couple hours.The lagged pipe I mentioned earlier seems to come down,is there a cavity that you could maybe use a mirror or phone camera to see if your leak is from further up

I'm afraid that's just a piece of old junk lagging - here it is from the side:

Have had heating on for nearly an hour now so will try inspecting again as it cools down
