Second floor no heat, no pressure

Hi,

Have a hot water system, with flow tees going to all drops. Taco 007 circulating pump. I get great heat to the first floor, second floor, no heat at all. This is a single zone install, that was working. If I open the bleedrs on the second floor i get about a one second hiss and it is over. Please help!!!!!

i have 22 psi

Ed, i have 22 psi at the boiler and now when i bled the upstairs one of the loops is heating and the second is not. it has two bleeders on it one at the floor on the flow up and one at the middle of the loop after the fins and before the straight pipe on the return. When i bleed the first one before the fins it gets hot right there but not through the entire baseboard. when i bleed the second it never pulls hot water.

Bleeding

I presume you are bleeding with the circulator running. Try it with the circulator off. Sometimes it works better one way sometimes the other.

Gave that a try to no avail either .....
I did see something that i didn't before when i went back downstairs ... i have monoflo tees and right after that what looks like a check valve with a nut on the outside and a screw on the inside ... I don't know what this thing is but it looks like it could be set incorrectly ... any idea what this thing is and how to set it?

Check Valve

The device you describe is a balancing valve. It is nothing more than a butterfly valve used for decreasing flow to part of the house. When fully open, the slot will be paralell to the pipe. If you determine which zone you are having trouble with, you can close the other balancing valve to force all the flow thru the troublesome zone. This may or may not help in bleeding.
