Is there anyway to adjust it? I dropped mine about 3 feet onto a carpeted floor. It now reads 4 psi not installed. How can I get it back to zero.....

 

apply pressure to it to see if you can get it to reset after removing the pressure source.

If that doesn't work, buy another one. Recalibration will cost more than the gauge itself.

 

i just want to move the dial to 0......

i tried sucking/blowing on it....it move but goes back

if it can move just from a light drop like that, im assuming it can be easily moved, i just wanna know if you gotta take the front glass off or you need to do it from behind

 

try dropping it the other way, or bang it to move back? i dunno. ( im just giving advices, dont try it tho , unless you want to )

Mines 1psi off, but ill learn to just live with it. eRr..
