Here's a "before" pic
The original purpose for the extra check valve, Schrader valve and bleeder orifice down in the well was for causing air to be added to an non bladder tank at the start of every pump cycle. Now that you are using a bladder tank, air is no longer needed or wanted since as already stated, bursts of air from your faucets will result.Is is reasonable to assume that the check valve will actually allow the water to fall back down into the well (utilizing the schrader air valve)?
No. The check valve in/at the pump will prevent water from falling.\Is is reasonable to assume that the check valve will actually allow the water to fall back down into the well (utilizing the schrader air valve)?
Isn't it supposed to be installed down the well, below the pitless valve, which would require lifting the well pipe?
Or come up with a system that lets you suck water under the floor down to the frost line.To drain the system below the frost line you will either need to lift the pipe/pump off the pitless every time, or lift it once, and install a bleeder, so it can drain without having to lift the pump up.
When the pump shuts off each cycle, the check valve will prevent the pressure tank from pressurizing the line back to the pump. A bleeder orifice located in the drop pipe within the well will open when there is little pressure, to allow the water in the pipe to drain back into the well. Water can not drain back unless air is permitted to enter so the Schrader valve will open when there is suction, permitting air to enter, thereby allowing the pipe between the Schrader valve and bleeder orifice to drain and become filled with air. Once the pump is reactivated, the air in the pipe will be pushed into the non bladder pressure tank, thereby regularly replacing any air that had been lost from the tank.
Since no air will now be needed for the bladder tank, removal of the check valve will keep the line back to the pump under pressure, which will force the bleeder orifice to remain closed under normal operation. When you wish to drain the system to prevent freezing, shutting down the pump and opening a faucet will drain the pressure from the system, allowung the bleeder orifice to open so the plumbing can drain back into the well while the plumbing becomes filled with air from the open faucet.

If you could run a smaller tube into the poly from the top, and suck, air gets sucked in around the smaller tube to replace the sucked-out water.I can't think of an easy/elegant system to do that. Putting suction/vacuum on the plumbing , I assume, would suck water up from the well.
This is awkward, but...
