Hi All,
I've just had a new W-B 30CDI combi installed with rads and the heating loop appears to be losing pressure over a period of a 3-4 days . If left completely alone the system drops right to zero, then substantial amounts of air appear in the radiators.
- it isn't the PRV, there is no evidence of leaking through this.
- there's no evidence of weeping from any joints, or apparent damp spots
- could it be the automatic air vent? How long after an installation and start up could I expect the system to be air-free from the AAV? Am I just seeing trapped air venting out of the system, causing a pressure drop, until eventually the pressure drops so low that air gets sucked back in through the same route?
any thoughts, would be much appareciated!
