One pipe Steam system

Rob_38 Member Posts: 15
I have a customer with a "one pipe steam system" with a supply and return from each radiator with no trap of any kind. This part of the system works great. The new part of the house has a "Two pipe system" with supply and return piping with a 17-C Hoffman traps on three baseboard units. Pipe size is 11/2" to the trap then reduces to 3/4". My problem is the one pipe system this is tied to is putting system pressure on the return line and the trap thus not letting the system work. So I looked at taking the trap off,capping the return venting the unit and making it a one pipe system, but my piping does not have fall back to the boiler for the condensate to return. HELP ME, Rob.
