hi all
my vailant boiler has been losing pressure at a steady rate (2 bar to empty in about 2-3 hours) for a few weeks now. i've had a boiler guy round and he said the boiler is fine, a plumber has been round and said there are no leaks at the rads, a leak detection guy round with his fancy toys but he wasnt able to find a leak. any ideas what else (if its not a leak) could be causing the pressure loss?
There's no water damage anywhere on the ground floor ceiling, ground floor floor board have been lifted and none of the pipes are leaking. the only place we can physically see is in the kitchen behind the units where the pipes are in the concrete floor. the leak detection guy did check there but said there was no trace of a leak...... i'm approaching my wits end so any help/advice would be appreciated
thanks in advance
