In the second to last picture you can see the Pit less adapter in place with the Tee handle that hasn't been removed yet.

I am down 450", but I live on a ridge top. Did you have to pull an old pump?

Tom, Yep, 450' that's deep. You had your installed?
We took it out, had the well deepened by 100', than we installed the pump adding 80' of pvc and wire. It was very heavy on the way out with the water in the down pipe.

DANG! That is awesome. Thank you for sharing. And I thought I had a deep well when we went from a fifteen foot to a twenty-five foot for the sprinkler system.

I like the way you did it looks like you saved a lot of money by using some innovation.
Our well was drilled so that the place could be sold, and it was only a few years old before the pipe broke and had to be replaced. The people who drilled it were clowns, they drilled past one water table to a second one and put holes in the plastic pipe in the area where the first water table was. for this reason they never filed a well report. The water we were getting was brown with rust as the well was over 800 feet deep. The people who fixed it found that there was plenty of water at 450 feet, so that is how deep they set the pump; even in the dry season there is 200 feet of water above the pump, and it is clear. They actually set the water flow limit (GPM) higher than the first guys. The people that fixed it also put metal pipe in the hole so it would be stronger.

Greetings, Why would you set the flow limit with that much water, how big is your pump?

Our pump will lift about 10-12gpm at that depth and the well should supply that. We do have a pump protector in case the pump out runs the refill.

I don't know; it is set at 10 GPM, it was set at 9 GPM before.

Tom, We had a flow restrictor installed in the well before we had it deepened. The restrictor is nothing more than a coupling with a small hole for the water to flow through. This was because the pump could out run the recovery rate of the well, we had it deepened, there is now 90 ft of water over the pump, so I didn't reinstall the restrictor. Our pump at that depth, 380' is rated at 10 gpm, the well can recover at that rate.
