I have a shallow well pump which draws air from time to time. Problem is that some of the air ends up in the pressure tank so I have to shut off the pump every so often with a faucet open to purge out the air. Is there a way to trap and vent the air automatically? I have seen air vents for boiler systems but not sure these would be appropriate for the well. It's not a big problem now as the water table is above average right now but during dry spells the water table drops and I end up pumping more water for sprinklers so I get lots of air and the pressure tank gets bogged with air almost daily. The ultimate solution would be to get a 100 gallon non-pressurized storage tank filled by the existing pump and a secondary pump that draws from that. I would like to do this because I would be able to get higher pressure and flow throughout my house but too expensive for now. I could also have a new well put in but the driller would be compelled to go 50+ feet and the water there would be quite hard so would also need a treatment system.
