I also have a well, who did you get to made it also prep for manual...I have been thinking the same thing for my well. For me, when power goes out no water, when the grid went down for 3 weeks a few years back, water was the only thing I needed...used match to start gas stove and kerosene heater for the home. Did you do it yourself...my well is only about 35 foot deep. The pump has been replaced and the pipe and pump were pretty easy to bring up but I had a well man do it....
Granny, there’s a new product almost ready for its formal launch, Flo-Jack. www.flojack.com It’s a manual pump that is easy to install alongside your other equipment, and not all that expensive.
We recently had the original company that drilled the well out to replace some apparatus that had been on it for 25 years; so I reckon they did any alterations needed. Husband made a manual well-bucket (tube) from PVC Pipe that he could drop down into the well and draw out water. “Jerry Rigged” it so it would work; he’s handy that way. Couldn’t use a regular metal bucket, so the soft, smaller PVC Pipe is a better choice not to tear anything up down there. (I want to get one of those Bio-Sand water filters to use in a worst case scenario. We have sulfur water, and filter the fool out of it with modern filters; but those wouldn’t work in an emergency.) Our well is deep, and I’m glad for that. Quarries blasting out here broke open a sulfur vein into our well water table 24 yrs. ago; had good-tasting water at first. Tests don’t show anything nasty in well; just that sulfur is crummy tasting to me and nasty-feeling to bathe in. Twenty-five years it’s worked well for us with filtering.
If you google “pedal powered pump” or “treadle pump” you can find hundreds of designs for homemade human-powered waterpumps, at least one of which should work for your needs.
