Have inherited an old LPG system in an old house in the country where previous owner renewed central heating pipes under new concrete floors.
System losing pressure every day and has to be topped up.
No water leaks or damp spots to be seen so can only assume under concrete and draining away.
Is there any way of finding this leak?
Any advice welcomed.

Got a cat?

Look for the spot that the cat lays in, theres your leak.

Or you could use a inferay theromoter, fan it across the rooms floor until you hit the hot spot.

How did you know we had a cat :)

Good idea the infrared thermometer, hadn't thought of that.
Any idea where I could get one?

Inferays can be bought from auto part stores as well as Grangers.

How did things go for you I have the same problem and the plumber is having no look finding it. Let me know how things turned out.

Thanks

I guess the guy who orginally did the job didn't pressure test it over night to check for leaks..before allowing concrete to be poured big mistake..

The cat thing works, but the theromometer works better.
Leaks in slabs are a real pain sometimes to find, you really have to look hard and think like the guy that put the system in like whre would he make up his connections.
The thing to look for is a area that has a higher heat area, or you could use a humidastat to find a damer spot in the slab.
