Hi,
I own a Valient ecoTec boiler combi boiler which is located in the loft.
I am losing water pressure daily but am at loss as to what is causing it.
During the day, when I pressurise my system to 1.5 bars, it runs for 8 hours before losing, any pressure.
In the evening, once I pressurise it, it runs for about 20 mins before it loses pressure.
I have no rads in the loft, there are no water marks on the ceiling of the ground floor so the system is not leaking on the first floor.
I have also isolated the flow / return on the ground floor so no leaks there.
All trv valves have been checked and no leaks.
A gas engineer states the boiler is fine and that I have a water leak. At the rate that I am losing pressure, the leak would have showed up by now.
I am at a loss as to what could be causing it.
I would welcome any advice.
Thanks
Aaron
