The blend door on the heater box will also fail to full heat if it breaks.

Anyway, back to earth... Did you put that new valve in place? I'm a little unclear on what you actually did and tested so far.
man any advice you give is tottaly nutso and un informative in tottaly errevalant terms to what anyone talks about don't need you here on earth with normal sane humans anyway lolz.
