    A Customer wants to add another radiator to a monoflow heating loop. The new radiator will be in the basement. I'm not working on it somebody I work with is. He is a part timer and I'm very concerned that he did not get all the info needed. The basement has never had a Radiator before now He is adding new monoflow tee's, but does he need to up size the pump. I'm told the heat lines are in the ceiling of the basement so he is doing drops down for the basement radiator. Is this right. I know how monoflow works but would not know how to really set it up, and adding to it is another ball game. If I had more info I would give it. I'm asking because if there is a problem later I will be the one sent back because I know about heating than other guys in the shop. I would like to know what was done wrong.

    Thank you all for the info Pat

    Radiators below the main need a feed AND return MonoFlow tees. In addition they have to be separated far enough to create resistance to force the water to circulate through the radiator. Placing them on either side of an elbow with sufficient distance between them is usually adequate, unless there is unusual pressure drop/resistance to the radiators.
