If it ain’t broke, don’t fix it??
Not trusting my $35 manometer, I ordered a Fieldpiece manometer. With the Fieldpiece my new AOS is reading in the high fives cold and 5.32 - 5.41 warm. The cheap manometer is off by ~1WC
JPF indicated that anything above 5.0 warm is candidate for replacement. The Pelican article says 4-7 is ok. I think I’m going to call it good at 5.32, watching for symptoms and monitoring WC regularly. I really don’t want to go back in and risk breaking the AOS plastic squeeze clamps unless I really need to.
What do you guys think???

4-7 is OK on a cold start, but 5 is our limit warmed up. Yours is marginal, so I would leave it alone, but check it regularly to see if starts going up.
Nice manometer by-the-by.....
