Pressure tank installed and heater ducts moved to rear side of furnace. Some plumbing and wiring required a little rerouting. A lot of wasted space before.
Update: I reworked this area in Sept.2014 in conjunction with water heater relocation. I am sorry I neglected to take photos of the upgrade to this area. Basically, all of the water lines coming to the left side of this picture were eliminated except for the black tank flush line. I now have short feeds of the cold and hot water lines to the area along the wall to the left of the pressure tank.
Please check out my hot water tank relocation album.
