I just about have the front returns run for the store. The bottom of the U-seal extends all the way back to the deviding wall in the front basement and turns the corner, runs across the back wall and part way up to toward the front on the other side ( like a big U around the rear perimiter of the bldg.) I am trying to cut down the number of fittings and pipe ect. so my question is,if the top of the U-seal is my new false water line, is it ok to drip the returns from the blue room, the office and a new feed to the library, into a single return? This would T off, and step up, from the loop at the floor, that is off the bottom of the U seal. This ganged return would have to sit about 18" above the floor and (at the boiler water level but well below the 5 foot of the top of the U-seal). If I am right they would drip into about 3'-4' of water because of the new false water line. The advantage is one pipe just above the pipe tunnel and still below the false water level. If you think this will work, what size pipe should I use for the ganged return? It would have about 230 sq. ft of radiation dripping into it. the floor extention loop of the U-seal is all 2". I hope all is well with you and yours. Thanks as always T.
