air valve is located on the side and will accept a standard fitting from
a bicycle pump or air line.
2. Check the pressure with the power off, faucets open and no water
flowing (zero water pressure).
3. Install a valve and isolator hose between the system and the house
plumbing to aid in pump removal for servicing and for reducing noise
