I see that 1 inch of water is about 2.5 mBar, so at most it's off by less than an inch, which still puts it at about 17.5 mBar.

I'm confused what it means, diagnostically, to have 'too much vacuum'.

What causes that? How do you fix it?

Note: I wonder if the large reading is an artifact of the large loop of my water manometer?
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
