well for those who were concerned with the PVC system I was going to put in, here is what we decided to do. Went with galvanized pipe. 1/2 ". came off the compressor with a shut off first. Then went with a filter regulator with the hook up for the air guns etc. then we ran the pipe up and over the garage and back and forth to get at least 60' to another shut off with a drain. we have 2 drains before the filter and another regulator right before the decadent and the last regulator is used to drop the pressure for the guns. have not had no problems yet and it is working great to paint with. This way I can have 120 PSI for the guns and 40 or what ever I need to paint with at the same time. I can also shut off the valve to keep air out of the decadent and using it up if we are not painting. Cost with all the line , shut offs, filters and regulators was under $250.00 I believe. We are happy with it and I think it is safer. Thanks guys.
