I was hearing the sound of water running in my baseboard heating everytime it kicked on, so I went down and checked the furnace to find no pressure on the gauge that says water psi? I tried to manually fill it with auto fill? regulator but I cant hear any water running through it. The system goes from the well to the backflow preventer to the auto fill(I think thats what its called). Do these things fail? or could it be something else. I think the backflow preventer works because I have hot water at the tap.
Any ideas would be so helpful!
