    Good morning. Having a vibration issue with my TK Jr. Usually after a bath/shower, when the unit is "calling" to heat water, a vibration starts, and depending on the water pressure in the system, it turns into a rumble.
    The pressure gauge is constantly low. The only thing I've found to remedy the situation is to constantly add water into the system, to bring the pressure back up.
    From what I've read, it looks like I've got a leak, that keeps dropping the pressure within the system.
    My TK Jr. feeds into a holding tank, and also runs my in floor heat, in the basement of my house.
