I was attempting to test the air pressure in my water pressure tank.
THe instructions state I need to empty the tank prior to testing the
I emptied the tank out. I took a pressure reading of 0 psi.
While I added air to the tank some water came out. I probably got a
least 20 gallons out, where did this water come form?
Anyway I got up to 20psi, but it then let out more water and droped
down to 8psi.
My pump switch is 40/60. It seems to work OK. I was just trying to get
the tank to it's 38psi orginal spec.
I put a new psi guage on and it shows that the pump goes on at 40 and
off at 60.
Still confused about the air on the tank?
