Two questions.
- Is the water well head above or below ground.?
- And how deep is the pump set?
If the pump is set on a pitless adapter than you can pull the pump to drain the house down, but you need to bypass the treatment system first, shut off the pump and drain the pressure in the sytem down to zero.
The weight of the pump and piping have to be taken into consideration also, If it is very deep then you will need help to pull the pump up.
Most pitless adapters have a 1" NPT thread in the top of the adapter to thread a piece of 1"BIP into. Measure down to the adapter and add 3' to that length, buy a piece of pipe, threaded one end, and weld a 12" piece of rod or pipe to the bald end to form a tee. The tee is to prevent the pipe from slipping through your hands if it slips.
Shut off the power to the pump.
Drain the system down by opening all the faucets in the house, sinks showers tubs. remove the hoses from the back of the washer also once the system is down to zero. Leave them open.
Put the treatment system into "Bypass".
Then pull the pump up, if you can pull the adapter to the top of the well and hang the adapter on the well pipe. If you can't have a pipe vise there to hang the pump from.
Leave the pump there until you are done with the draining operation.
If your water tank has a boiler drain on it, attach a washing machine hose , routed to a bucket to catch any water coming back to the tank.
Have a "pancake" style compressor with you.
Make a set of adapters to attach to the compression joints at the stops under the sinks and toilets and an adapter for the shower heads also. Take the connections apart and then attach the adapter and blow the lines back to the tank, highest to lowest in the house.
Once you have the water blown out of the system, you can start on the toilets and traps, use a shop vac to suck the water out of the toilet's tank and trap. Fill the trap with RV anti-freeze.
The sink traps can be sucked out or blown out and filled with RV antifreeze, or a piece of 1-1/4 or 1-1//2" PVC installed with a cap glued on the end installed and the trap left in the bowl.
The showers, tub and floor drains will have to be flushed with antifreeze if they are not accessible from below.
Once you have the piping drained , the traps drained and sealed, you can then remove the treatment system and store in a warm dry place.
Reset the pump and close up the well.
If it is a jet pump system then you have to drain it with a hose run to a drain or
I like to leave the system open, but most people want to be able to walk in and turn on the pump and have water in a few minutes.
I also like to disconnect the pump wiring in the well to prevent vandalism or accidental flooding of the house. I install wire nuts and tape on the wire from the house to prevent short circuiting.
