Navien tankless 240
Heat circulation on
It's a new sound, we've had this tankless since 2016. Was inspected a year ago.
When I look at which pipe is making the most vibrations, it's a black pipe on the right side of the unit.
Should I turn the unit off immediately and have it inspected by a pro?
edit: the pipe that is knocking is connected to the expansion vat and the unit on the right hand side
