2 pipe steam dry returns no traps
We are moving some pipes and Radiators on a two pipe steam system. Each radiator has a radiator valve on the supply and the return with no trap. The radiators also have vents on them. Some of the supply and return risers pick up more than one radiator. There are teo mains and at the end of each msin there is a loop seal. The homeowner says everything heats fine and is quiet. I’m trying to figure out if I should put traps on the stuff that we are doing or leave it the way it is. At some point before the next heating season we will be replacing the boiler and installing a vaporstat.
