Need help with Water well.

[valley]

Thanks for getting back with your thoughts. As I mentioned, hasen't closed escrow yet. Half of the pittless adapter, the part not bolted to the casing is gone. Don't know if I can find out what make and get one to match, I most likely have to dig down and install a new one.
The house is a repo, no clear information about the well. I don't know of any contamination in the area.
Wifey talked to a couple well drillers, both want $1500, one mentioned they would use an acid first.
I plan to get a pump not sure what kind yet. Think I'll go up and talk to the neighbor.

I recall dropping a stick of dynamite with a weight down a well years ago, (when we could buy it at the feed store). cleared, or restored wells around here. I also recalling that sometimes the roof of the pump house ended up a couple of properties away.:laughing:

The deepest well I have installed a pump in is 80feet.
Can Poly pipe be used in a 300foot well? Has any of you done that?

Well guy says they use PVC with stainless couplings. what do you think?

Our well is ~710 feet. They used schedule 80 PCV with threaded ends and stainless couplings.

At the very top of the well is a galvanized T, which holds the weight of the entire well string. If I had it to do over, I would also make the top section of pipe galvanized. One time I hit the T hard enough to break the PVC pipe below it. This cost several thousand to fix. If the top section had been galvanized there would have been no problem.

This is not really a DIY project. If you drop the well string, you are in a world of hurt, and it gets heavy with the pump, the wires, and all the pipe.

If you decide to do it yourself anyway, look up how to do it before you start. The wires need to be very heavy gauge, they need to be tied together every 5' or so, and they need to be wrapped around the well string as you lower it.

Actually, wells are cased all the way down sometimes. We case ours 500-600 ft. It depends on the ground. When you're in rock, you don't always need casing. If the borehole won't stay open on it's own, it will be cased all the way down.

Its no biggie to put a pump in. Anytime you pull a deep well pump you should pour a 16 oz or so of bleach in there. This will shock the system and clear any dangerous stuff that you may have introduced from the topside. This is what the well installer folks do around here and have been doing so for 20+ years.

As for the pump. 45 ft of standing water in a 6 inch cased well isn't an awful lot of water. To start with you should not put the pump on the bottom. So the normal above the bottom is approx 20 ft. This leaves you with approx 25 feet of reserve. you can determine that 25 ft * 1.347 per foot equals roughly 33 gallons of water. Lets say you put a 10 gallon per minute pump. You have about 3 mins of running time before going dry. That is only for the reserve. You also need to factor in the rate the water will come in. say 5 gallons a min. This equates to roughly 4.5 mins of run time.

In essence if the rating (check the side of the well it should have the rating on it) is close to this you do have a basically dry well.

200PSI 1" Poly Pipe will work in a well - here in the east they use it to about 400' with pipe and 10Ga submersible pump wire. Our well is 400' deep and 1.5HP pump is at 365 on 1" 200PSI poly pipe.

The cost for a pump at that your depth (I would get at least a 1 or 1.5HP) will be roughly $1000, pipe $400, wire $400, then torque arrestors and pipe spacers a few $, then a pump tank $400 and switch setup (do a low pressure cutout type to stop the pump in case it runs dry). You will have $2000 or so in this setup and can test it out.

If you get 400' of pipe and wire you at least have enough to put in another well or if its decided to drll this one deeper you have enough pipe and wire to run a new well.

Personally I would have the well co come out and test your well with the agreement/understanding that if it doesnt produce enough water you want a solution (new well/fracking/drilling deeper) to your water issues. Essentially find a well company not just to drop $1500 but to provide a solution.

Here's a link to a site where you can spec out costs pumps, piping and stuff for a well Aqua Science, the Most Trusted Name in Well & Water Treatment Systems

That you can see a neighboring well does not mean you will have good water. I live on the east side of a highway - drilled well, 65' 24gpm. Neighbor right across street went over 90 ft and got barely enough gpm to be useable. Same deal a mile up the highway. New well was artesian, ran for a week before he could cap it. right across street again barely enough to be useable. Highway runs down the bottom of a shallow 'valley'.

OK! I talked to the well guy who was paid to check out the well by the real estate broker. He says the well is: 335-340' with the water at 256'. He said he would put in the pump and tank at around $3500

Not sure if our measurement would be off by that much. We'll check it out again with a string, that has a knot every 10'.

You people have given me a lot of good information. I thank you.

I forgot how much our well cost to be drilled but it was around $3-4K. That included drilling, casing, grout, pressure tank, pump, etc. Our well is around 250 feet deep and the static water table is at 21 feet. $3,500 seems like a high amount to drop in a pump and install a pressure tank.
