I'm doing a service that requires a 16' mast. I figured that I would be able to get the shorter length of pipe threaded (2.5" gal) to screw into a meter hub. The local plumbing warehouse (Blackman Plumbing) would thread my pipe but, I'd have to buy a length from them. After the "full trade discount" they wanted $182.00 for the pipe (10') and then $20 to thread it. Ouch. My inspector seems iffy about using a compression connector. He suggested using a "myer's hub," but that's threaded top and bottom. Any help would be appreciated.
