Topping up each day and loosing 1bar or so in a matter of hours

and they've got to the stage of suggesting taking up flooring to
inspect pipes and junctions. This is getting expensive and
disruptive! BG have a £1000 limit on their part of repair and making
good costs. Have people tried:

(There are others)

Any experience with one of these companies? Pin-pointing the leak
position may save money in the long term, even though the survey
will cost a few hundred pounds. I've yet to explore the home
insurance angle to reclaim some costs.

If you can't see any damp patches or pools of water indoors, then the water
is going outside. If it needs topping up daily, you couldn't possibly have
missed an internal leak as it would amount to a small bucket full every day.
As others have said, the water is being expelled outdoors via the pressure
relief valve.....and I find it impossible to believe that BG didn't already
know this


Are the floors downstairs solid or suspended? You could easily miss a
modest sized leak there. Years ago, one of my neighbours had a failure
of his bathroom grey water drain which created a small lake under the
living room, and he only discovered that when he had to take floorboards
up for rewiring.

Wouldn't that have created a stench?
