Before I start don`t have a go at us if i`ve not explained the problem in detail because i`m asking it on behalf of somebody else
Anyhoo the problem is with a Valient (i`m sure thats the make) combi condensing boiler it looses all its water pressure in more or less a day. There is no leaks on system what-so-ever, the owners been under the floor and I presume if it was leaking upstairs it would have showed more than a wet patch by now. So is it possible and if so whats causing it to loose that much water but without any leaks.
Cheers
