Webster question

I looked at a job yesterday, where as it looked to me there were no drip traps that I could see at the end of the mains. Instead, it looked like they rolled two 90's down from the main end, creating another condensate line pitching back to the boiler room, which tied in above the boiler by the boiler return trap & air elinator. System is quiet, in existence right now, but I would like to correct any mispiping. This is a very tall basement, with plenty of room for dimension B.I'll try to get some pictures if I can. Has any one else run into this?
TIA for any help.

I should add..

that it looks like there are some crossover traps on the end of the mains, then tying in above the boiler. This may not make any sense right now, so like I said, I'll try to get some photos to explain this better. Thanks!

Steamhead (in transit)

As long as

the condensate returns from the steam mains are not routed thru the Return Trap, it will work fine. Make sure those crossover traps are working, otherwise the system will heat slowly.

Piping elimination

Hi Frank,

I think that this is going to be a complete re-pipe to open up the boiler room & bring it up to code. I would then have to add an F&T trap to each one of these condensate lines, then adding venting to the dry returns, tied in below the water line.Like I said this a very tall basement.We maybe using a small condensate pump, my old boss is insisting on this item. I might be able to talk him out of it. I think that I might have a theory, as that I haven't been in one section of the building yet, it was locked up the other day when we were there. It seems to me that the steam main braches out of the boiler room on either side of the building then comes together in the middle of the building on the north side & then runs back into the boiler room. As soon as I see this section of piping it will probably clear things up a bit. BTW do you ever have a problem explaining to other contractors, whom are not familiar with vapor system that these systems run on ounces, not PSI. Sometimes I feel like a broken record. Some of the background info on this project is that it is for our union trades building downtown. I am working in conjunction with the JATC (Joint Apprenticeship Training Committe)for UA local 111, and one of the contractors I used to work for. Mainly, because I'm the only one from the local that's done the most work on this system, that isn't dead or retired. I now work for the university, so they called me in to give a helping hand. I'll keep you posted! Thanks again Frank!
