What is Water Column 

A U-Tube looking device! I see what you did there. Thanks for the video.

Do you ever test a 2lbs. CSST system with the regulators installed.

I have a Westinghouse triflex generator and I can’t get it to start. I called Westinghouse and the lady said it won’t start until the PSI is right. She said Natural PSI Watercolumn .02 to .04 6 to 12 “ Who do I call to set this? Thanks for your help!
