    pump pumps but water is not flowing

    I have a hot water baseboard system with 2 seperate pumps. The pumps swicth on and rotate , however one zone does not appear to have water in it. I have watts pb56 purge valves, and when I rotate it to purge no water or air comes out.It has the slotted screw for the butterfly and I can turn it and still dont get water????

    Either no water, blockage or frozen

    Don't overlook the obvious

    Maybe the circ is rotating, but not generating enough head to do the job. Half burned out,or ?? Years ago I saw Chrysler car getting hot- 'stat was OK, appeared to have some flow in the radiator as I remember.
    Water pump was turning... on the OUTside anyway. The impeller had cracked on the shaft. It may have been turning a bit, but wasn't doing the job. A new water pump solved the problem. Kevin
