Just as an update. I bought a Pancake compressor from HD on a really great special. In the meantime, I ordered a regulator for the 15gal PC that was broken/leaking. The replacement regulator worked perfect, so I returned the new one which I never used....
As an FYI, I bought the pancake w a $500 HD gift certificate my wife gave me for Christmas. in early January, I was informed by my Power COOP that I will need to upgrade me Meter Loop pole/Service panel to the tune of about $2000 out of pocket costs....W the gift card, I bought 90 ft of 2" sch 40 gray conduit and still have more to go...hope everyone is having a great week - tstex
