CEC Plumbing

I had this company install plumbing for gas lines for a restaurant I'm opening it's 06/25/2015
They never tightened the hoses in the back of the equipment. They lost the permit blamed me and had us go out of our way to get a new one. I was checking my pizza oven and it won't push gas to the bottom oven. They just put in a new regulator and hose and now it doesn't work.I called and talked to [redacted] and he didn't think about the problem just Threatened Me and said its my problem. do yourself a favor and whoever reads this find a reputable plumber who has great reviews don't get stuck into a problem like I did
