Also you can put the sniffer in the drain tube to see if you have an evaporator leak, I would also check with UV light to see if u can see any leaks

Good info, thanks

temp definitely affects the pressure both running and not. There is a guide on the internet for pressure vs ambient temp.

leaking Schrader valves is probably the most common problem. I never trust the ones that come on the aftermarket items. I take them out and replace them with higher-quality shaders.

There is a die that they use to see if you have leaks
