      I have hot water baseboard heat. No matter how many times I bleed the sytem, (this is through drains in the basement at the bottom of the 3 zones, there are no bleed openings at the top of the house.) I still get the sound of water running through one of the zones. I have checked for leaks all over the house but can’t find any. Is there something I’m missing.

      You might be missing the system height pressure requirement, a pump on the return instead of on the supply problem ‘pumping away’, or a purging procedure problem.
