Water Wells

What is the best way to check the durability of an old hand dug limestone cased water well?  Is it as simple as dropping a pump down and seeing how many gallons it'll produce before being pumped dry?

 

If it isn't producing up to expectations, is there anything we can do to boost performance?

Hey Shaggy, my well man has a formula that I think he pumps full out for 10 minutes and if the well handles it without overpumping the casing, it`s good.  For handling a household and a small cattle herd, 10 gallon a minute is good. 

 

I got a submersible pump down 140 ft, if I`m filling a sprayer it`ll overpump the casing so I run it about 3/4ths open and clean the nozzles and come in and argue with the liberals on the forum page  Smiley Happy

 

At a different place I got a jet pump about 30ft down and that will knock the cup out of you hand and I can`t imagine ever overpumping that since the water table is so high.   Then I have a old stroke pump on a well, in case of the zombie apocalypse.

 

But you could "DIY" buy a 4" submersible pump, go down 50 or 100 ft and see if it pumps enough to suit your purposes.  As far as I know, all you can do is put the pump down deeper and if that doesn`t work you need a new well.

Re: Water Wells

BA, this well is only about 20-30 foot deep and I've got no idea how old it is, probably 50 years or older.  I've got a 1" pump powered by a small 2 stroke engine I might try.  I'll pump it full out and see how long it takes to suck air.  If it can't keep up with that small of a pump It'll probably never work with a solar or wind driven pump, unless it is a calm cloudy day.  Smiley Very Happy
