    2009 w/222k. Coming from the inverter pump or near that area. There is turbulence in the inverter tank and I can feel it vibrate so does this rule out the pump? It only happens once a month or so and will last about 30 seconds to a minute. Please advise tia

    First see if you can get any air to come out of the air bleeder valve... There's lots of info on here and on Youtube if you need to learn how to do that.
