I can't seem to pressurise my Valiant 824 turbo max. It doesn't normally lose pressure, so I rarely need to pressurise but when I do, I just open the valve and water gushes in. However I tried to add a little pressure the other day and no sound of rushing water and pressure did not rise. If I leave the valve open, pressure does rise, but very slowly.
I had the boiler serviced 12 months ago and I don't think I've needed to pressurise since then, so I'm wondering if the engineer closed off another valve. He's actually due back in a few days for this year's service, so will ask him about this, but would like to get opinions beforehand.
