Well, if you leave leave the water heater by-pass open, you'll need to pump a 6 gallon tank full of air ... enough to get it pressurized, enough to continue pumping that air through the rest of the system.
If you do not drain your water heater, you will only blow out some of the water heater water, most will remain in. Intake to the heater is at the bottom. You'll pump air through the water. Out-Take is at the top of the heater. Once the water gets below that spot, you'll be pumping air, but not water.
Drain the water heater, put it on by-pass, then pump the air! When done, flip the by-pass back on. If you pump the pink, leave the bypass closed until you've flushed all your lines in the Spring. After flushing the pink, THEN un-bypass the water heater so no "pink" will get in it. If blowing only, drain, bypass, blow, then un-bypass so it will fill automatically with water in the spring.
