I have my circulating pump mounted in my basement for my OWB. My question is, on just two occasions now I have woke up in the middle of the night to hear the pump making a sort of "tapping" noise, it's not rythmic or anything... just random light taps. The pump is right below my bedroom so that's how I am able to hear it so clearly. My question is, what can be causing this? I went down last night and open a bleeder valve, it just spit a little and then the pump quit making that noise.
I've had no trouble at all with the pump up until now, and now I notice that it makes a light noise when it's running, almost sounds like air bubbles passing through it. Never had this problem before. I did go out and check the water level at about 2 am this morning, it was fine, but I did just top it off a little.
To me it sounds like some air bubbles being trapped and getting pushed through... just confused as to where they are coming from.
Anyone had any similar problems???
Thanks
