adding traps to a two pipe system
I looked at a job the other day that has 8 two pipe radiators and 1 one pipe radiator. The returns all tie in to a common dry return with no traps, loop seals, or any other provision to keep steam out of the returns. The solution I have is to add traps to each radiator, plug the vents, and vent the main large enough to handle the whole system. The radiators are fed in the bottom and out the bottom. Can I still use a trap if they are fed that way? Most of the time that I see two pipe systems with traps they are fed through the top and return through the bottom. Thanks
