|In response to Re: pressure/temp. relationship|
: Sorry I cannot recall it, but a high school physics text will give you the formula for the pressure change vs. temp in a fixed volume.
Put the air test on in the morning when it is normally colder and check back an hour later if the pressure increases GREAT but if it drops uh oh
When I was a stationary engineer its easier to find leaks by using Freon like R -22 with dyetel plus we had pressure temperature charts so if one knew the temperature we knew what the pressure should be Or check with a Halide flame NO its not a great idea to check natural gas with an open flame LOL
