I'm losing pressure on my Vaillant Ecomax and it's definitely not a pipe leak, so my limited logic/knowledge tells me it must be expansion tank &/or pressure release valve related, and probably more likely the latter. Is there a way to ascertain the problem and if so to fix it, for example replace the valve. I'm fairly competent with spanner so if it's an easy fix I'd rather do it than wait a week in the cold for someone to come in.
All help greatly appreciated.
Thanks
