Jamie, you mentioned having some of those bi valve waste systems around. I am looking for one for my tub if you still have them. It is a low bell filler. Pics attached. Learning antique plumbing is a steep learning curve for me.
Thanks for any advice you can give.
Hey Jamie, Thanks for getting back to me so soon. The radiator valves look like standard 3/4" radiator valves, the steam traps at the radiators are Hoffmans, it looked like the steam traps on the ends of the steam supplies are fairly new and replaced the main steam vents. Found a used steam vent sitting on top of the new boiler. Talked to the project overseer about either trying to fix the system, or to convert the boiler to hydronic and re-pipe system accordingly with separate hydronic headers and home run to the radiators, and/or replace the boiler with high efficient ones, which is why I'm doing a heat load to see if the existing radiators can handle the lower boiler temp.
Question for you. Earlier you mentioned standard residential steam system and residential vapour systems are different. How are they different? I'm really curious to know. Thanks for sharing your knowledge.
