What about pitching the lines and then heat tracing the mains and aux drains per 8.16.4.1.3 (13 02ed)? I don't think this is the best option but you were looking for alternative ideas. Dewayne

I visited a site the other day which consisted on 1.5 million sqft of vacant industrial buildings built in the 1950's. The cost to heat these building is astronomical and the owners are looking for cut costs. They would like to convert the 30 +/- systems from wet to dry. Obviously the biggest obstacle is pipe pitch. Some of the lines appear to pitch, but most lines and mains are flat (caveat: I have not gone in with a level to check it, but rod lengths looked the same). The lines look like they could be pitched, but the mains would be a challenge. Are there any alternatives out there? I don't know of any, but I didn't know if the collective mind had run across anything. Todd G.
