Hi All,
September 2017 I had the expansion vessel, PRV and AAV replaced as the boiler, Vokera linea 24, was losing pressure and water coming out of the schrader valve.
Everything was fine for 4 months however it started losing pressure again, this time about .5bar every 24hrs.
I checked the pressure in the expansion vessel and there was nothing in it.
I opened a bleed valve in a radiator and inflated the expansion vessel to .8bar, as per the manufacturers recommendations, closed the bleed valve and repressurissed the boiler to 1.5bar.
However its still losing pressure. I've checked all the radiators and there are no leaks. I've also checked the outside overflow, where it would discharge water if it was a faulty prv but its dry. I tied a bag around the overflow and there was nothing in it after 24hrs. There are no leaks from the boiler.
I then drained the boiler and checked the pressure in the EV which was .45bar after only 4 days of repressurising it.
The firm that carried out the work did not supply the EV as their supplier did not stock it. I purchased it new elsewhere.
Does it sound like the EV is faulty or is there something I should check.
Thanks
