    Any one else have this issue? The circ. pump on the back of my EKO 25 seems to have a small air bubble stuck there. I notice a sound when the pump starts back up. Now I guessing it's an air bubble don't know for sure. It's still pumping water so it's not completely airlocked or anything like that. I just seem to hear more of a water rushing sound when it first starts than in the past. I had to clean lime scale out of my side arm and I think it started after that (a lot of new water put into the system). I have a small boiler air bleeder on top of the boiler and I've tried that and I have a air scoop on the primary/secondary loop in the house.
    Or am I hearing something elsee??

    What pressure are you running? Sometimes bumping the pressure up a few- 5 psi will help remove stubborn bubbles. Is the expansion tank connected to the inlet side piping of the pump?

    Another trick is to add a squirt of dish soap to the system.

    Bob,
    I'll have to look to see what pressure I have it set at.
    What is the soap supposed to do? Does it help to break surface tension? Are we talking a tablespoon (I don't have storage so my total volume isn't that big)?
    Thanks.

    Funny thing is I never got around to adding the soap and the bubble(s) must have worked them selves out of the system on their own.
    Does this mean it pays to procrastinate?
