No-hub would be legal in Seattle. Maybe a Chicago plumber here will know.
Is it legal to use 3" and 4" no hub cast iron piping in underground parking garage that is above ground of course for storm water applications in Chicago? Current piping is SV bell and spigot lead joint piping but all rotted out. I want to use no hub because of very tight areas where pouring a lead joint is impossible due to carbon steel boiler piping.
I haven't been is Chicago for over 40 years, but I am sure by now that No-Hub would be approved.
Licensed residential and commercial plumber
Ah, Illinois has some pretty stricken plumbing laws. They have their own code. If ou don't have an Illinois plumbing license I strongly advise you to find a plumber that does. Especially commercial work.
Ill have to look in code book. Its kinda unclear because its a parking garage and also not sanitary sewer.
