Underground rad pipe poss leaking - how?

Birdy

Appears to be water coming through bottom of bricks outside kitchen.

The only thing can think of is there is a radiator nearby which has pipe in ground. Gas heating installed approx 8 years ago, so what could be causing this now and best option to fix?

Bled rad recently as it was not heating properly.

Any advice gratefully received!

P.S. Will this be a major undertaking/cost? Cement floor, laminate on top!

TIA

I believe cement / concrete and copper aren't happy bed fellows - that is what I was told after I had a tiny hole appear in my copper water supply pipe where it passed through the concrete floor, the copper looked like it had been "eaten" away (we are talking teeny-tiny hole here, water was like it was coming from one of those atomisers the mist was so fine)

Whereever it passes through concrete, copper should be shrouded to protect the copper from attack.

Are you talking about the outside wall, if so I think that the bricks below the damp proof course always appear more damp than the ones above (depending on the season of course) because they absorb damp from the ground.

If you had a leaking pipe under you kitchen floor the first symptoms would be paint peeling off the wall nearest to the leak.

You could check by seeing if your header tank for the central heating in the loft is losing water, to do this you may have to temporarily tie up the ball !!!! to prevent the tank from refilling.

Edit. The system has deleted my rude word! If you think of a male chicken you will have it.:mad:
