WUR033, adjustment?
Trying to fix a cold running issue. Warm running is good.
My cold control pressure is low. 0,75 at 10 C (Spec 1.1 to 1.6)System and warm control pressures within spec, but at the low end.
Ideally I´d send my WUR for a rebuild, but living in Northern Norway complicates things.
Am I correct in assuming, opening the WUR (I´we done it before for cleaning) tapping the plunger for the Bi-metallic strip out a tiny bit, could be my solution for a DIY fix? Is there ANY way to say, roughly, how much I should tap it out?
