I bought a hose adaptor and placed a male air hose quick disconnect in it, set my air compressor at 40 PSI connect to my fresh water hose, then remove my whole house filter element replace the bowl, dump my hot water heater and turn on the water valve, the air compressor will pressure up the entire fresh water system, then simply open each fresh water user. don't forget the ice maker in the freezer. and the wash machine.
after that blow out the sink and shower drains and empty all tanks.
add pink to the tanks. yer done.
