I am new to forums, but have a problem that I can't solve. First of all I am a qualified plumber including unvented systems. My 3bar pressure valve has been dripping for a few weeks now. I changed it for a new one thinking seal had gone or bit of crap has got stuck but the new one also drips. The expansion vessel is charged up to 2 bar and the system never goes above 2 bar when hot. It might be worth adding that the system uses an air source heat pump so hot is never above 60 degrees.
I have ruled out (but could be wrong) the filling loop as i would see the pressure rise or stay constant but it's dropping.
any ideas or could i be unlucky enough to get another dud valve? are some valve makes better than others?
