Passed the inspection in my new house. Doesn’t take up any room! Can you find it in the photo?

Worked perfectly as a very small expansion tank for the tankless DHW coil in my small residential boiler.

I just added this to my tankless water heater. The issue I am having is my water pressure is at 80lbs and adding 84lbs to this is difficult. Every time I check for the right pressure I lose the pressure I need. This expansion tank is small but difficult to make work.
