Well Problem

[houstonscott]

My son is getting ready to close on a property with a 980' well.There is water at 500' and the pump sits at 760'. Turns out the pump had some problem and is welded it's self to the casing at 760'. The well is insured and looks like a new well be installed under the insurance. Any recommendations? Is this the best way to go? Who makes the best well pumps? Any advice for the new well?

Pump is under water and got hot enough to weld to the casing? Wow it looks like the water would have boilded. Sure it is not rust lime buildup or something on the inside of a casing?

Why would they drill a nearly 1000' well when the water is at 500' and then only put the pump down to 750'?

I think they wanted to be able to lower the pump if the water table changed in dry times. Why can't they breakup old pump and let the pieces drop to bottom and out of casing.

You need a column of water over the pump. You do not want the pump sitting at the bottom of the well to pick up sediment

This is a deep well but mine is 280' and my neighbors is at 100' go figure

Did the pump ever run dry?

That's going to cost big $$ to fix. The homeowner can claim he disclosed the problem, the insurance company can claim the previous owner, but not your son, is insured if it's not repaired before he signs. If it takes two or three months to work it out he will be hauling water for two or three months. I'd make sure it was in the contract it is the seller's responsibility to get water into the house if it isn't fixed when he signs on the line.

One thing I would check on is the pump and wire size needed for that much lift. That's way past most residential wells. I would really wonder if there is a pump made that would fit in a 4" casing and have the power to lift water 500 ft. + any additional to the fixtures in the house. It's possible but I would want to know for myself and make sure they used the right pump and the wire size for that pump's current draw.

Ditto

I don't see in your post where you are located but here in southern Ontario the wells are inspected and rated when drilled for GPM, this is on government files somewhere. The pump is then rated for the head pressure and flow rates, this will allow you to figure sizes of pump and wire. It might be useful to find this out. A local plumber/supplier will have useful info on this, you definitely don't want to pay for a new well that deep. I had a small split in my poly that was causing a drop in pressure and lost of head so getting older I called the local guy to see if he would take a look. He said it would be 4-6 weeks before he could get to it but he figure out what was probably wrong on the phone I have limited experience with wells and he made sense. I had water so it was not and emergency but could not wait so me and a cousin pulled it up and replaced the poly, shocked the well and was good to go. That amount of pipe with a pump attached is heavy, trust me. There are several methods besides trying to manually hauling it up. Mine was about 180 feet deep and it was not a piece of cake for the two of us. Some guys rig up a type of hoist, google deep well pump replacement. The local guys will know about local conditions and in my opinion it is worth the phone call.

That is a deep subject, I wonder if lightning had anything to do with the failure??Well head pressure from that deep must take a nice motor?
