Pressure dropping

[Sparkgap]

Could leave it and see what pressure it ends up at. Is this something new? I've had some issues with unvented systems following works, you vent the rads etc. and owner later complains that pressure drops. Turns out it's venting through the AAV inside the boiler as air in the new water gets out.

Hello spark gap , been in just over year and is recent problem it's dropped from 1.3 bar to 0.9 in two days , I am going to see how low it goes . Howy .

Hi,

Please allow the system to cool down. Top up the pressure to 1 bar set the central heating temperature to maximum. Run the heating for an hour or soo before turning off check the pressure also have a look outside to see if the pressure valve is leaking.


If it's a new build and a year old I'm pretty sure you can get the house builders back. Most new builds come with 10 years warranty.
