Had a friend ask me about air in the home’s plumbing pipes, the air spits out with the water. The house is 12years old on a well with original pump. He said the flow rate and pressure has not changed that he’s noticed. Is the water being introduced by the pump somehow?

Steve, if the pump’s in the well there is no suction line. There are two or three reasons for air in that system. The most likely cause is a worn impeller on the pump, causing cavitation.
If there’s a check valve at the tank, then the foot valve on the pump could be bad allowing the line to drain between cycles.
Again, if there’s a check valve at the tank, the supply line could have a leak and be draining between cycles there. Usually, if you get a leak big enough to drain the supply line, you’ll develop a sink hole or a really wet spot in the yard between the well and house.
