4. Close off all outlet valves to allow the pressure in the system to equalize to the pressure in the UConn water system.

5. One at a time, open the outlet valves quickly to force any air bubbles out. Close the valve and let the pressure build up again. Do this a number of times until you see little to no air coming out.

6. Close off the tap water inlet valve and turn off the water.

7. Open the in and out valves in the tank, and once this is accomplished, plug in a water pump and keep your hand over the the outlet. Feel that there is a decent flow of water through the outlet. Keep your hand there for a number of minutes. If the flow drops at all, unplug the pump and prepare to expel more bubbles

8. If the flow doesn't drop, it would seem that many of the bubbles have been expelled. Turn everything off, wait a few hours, and then repeat steps 4, 5, 6, and 7 again. If the flow is consistently strong for 20 minutes it is safe to plug in the heaters. The warming of the water may help expel any stubborn air pockets as well.

9. Monitor the heaters for at least 30 minutes. Feel them to see if they are getting hot spots on the top at all. The heaters do feel warm after a number of minutes running but they should never feel hot. If they are hot, unplug them, leave the pumps to run for a few minutes until the heaters cool down, and then unplug the pumps and repeat steps 4, 5, 6, and 7.

10. Even when it is assumed that all is working well and there is no air in the system, it is important to occasionally open the vta valve, especially in the first few hours of filling the tank. As the air becomes less and less of a problem the vta valve should still be opened on occasion. It doesn't harm the system to open the vta valve so it's better to see if there's air than to just assume everything's working well.
11. Repeat the entire process each time any measurable amount of water is added from the faucet.
