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.

" That sounds like you had a jet pump.
KC appears to have a regular submersible.
Our neighborhood got by with 2" wells (still at 200') using surface
water (suction) pumps for decades, then around 95-2000 they started
sucking air and you had the choice of converting to jet or punching a
4" and using a submersible.
Since I do not irrigate, my 2" well was holding but I decided to go
the 4" route preemptively in 2001 as part of a total overhaul of my
water system. "


Yes, jet pump sounds familiar and the drilled part may have been only 6" in diameter.
The well only made up about 1.5 gallons per minute and I remember running out of water (pump on continually) during one house party with over a dozen guests flushing and washing continually.

I can't imagine how you were able to live like that.

I think we are required to show 3.5 gpm here...

When we had our well installed the minimum flow the well guy was looking
for was 12 gallons per minute. They went down 512 feet. I've forgotten
what they achieved but it was something like 16-18 gpm.

We don't use it for the house or for human drinking water. It's for the
lawn and paddock sprinkler systems, pool make up water and for washing
cars and horses. Never had it tested but the horses have been drinking
it for almost 14 years and they seem to be fine, dammit.

It's shut off during the winter.
