I have an old (more than 50 years)farm well with a 3 " steel casing that I'd like put a deep well ejector in. Does anyone make a deep well ejector that will fit a 3 inch casing? Question 2: If no one makes a 3 inch ejector, could I drop a 2" pipe inside the 3 inch casing with a 2" packer valve. Basically making a single pipe ejector system using the 2 inch pipe as the casing. The well is only 70 feet deep, but the water level may not be above 25'.
