When I built a Cape Cod style house about 18 miles outside the old city limits in 1974/75 we had a 165 foot well drilled in the back yard.
We had the pump and water tank in the basement. Two hoses went from the pump to the venturi valve at about the 150 foot level.
Then a short 10 foot length of tailpipe was attached to the bottom of the venturi valve with a filter type of valve on the very end.
I can't remember if there was a 3rd hose to provide air to the well but do remember installing one in the top of the concrete cap that covered the well crock at the surface. I believe the drilled part was about 8" in diameter.
We sold that house to return to the city in 1985.
