System type: Pumped - differential controller
System appeared to be working.
The tank, controller and pump are all within a wooden enclosure located next to the residence. The enclosure was very dirty, exhibited rat droppings, and had a terrible smell. The controller appeared to be working.
The electrical to the water heater and controller appears to have been modified. The supply electrical to the water heater was 120V (should be 240V) on AWG 12 (should be AWG 10).
