bad well pump or pressure tank?

Hello everyone. I am having some issues with my well and I need some help. First some history on it:
  • well was drilled in 1994
  • well is 252 feet deep
  • well has 214 feet of casing
  • well has 4 inch diameter
  • I live near a wetland
  • well has submersible pump with 230 volt control box(1hp)
  • I have a whole house sediment filter after the pressure tank
  • water has 6ppm with iron
  • on 12/2017 my well started making noises and losing pressure. Called a repair man that my dad used to hire and he changed the pressure control switch, pressure gauge and the lever that goes inside the pressure tank(its galvanized steel).
  • two weeks later he had to come back out and pull the pump and found a hole in a section of galvanized steel piping that goes to the pump
  • I asked about replacing the pump and he just told me to "keep an eye on it".
  • 5/2018 the pump goes out and is replaced
  • they had to lower the pump 20 feet so that the water can flow can be drawn. they were hitting water at 75 feet
  • on 12/2018 i wake up and there's no water in the house and i go outside to hear the control box running and no pressure on the gauge
  • this was the morning after a thunderstorm came through the night before(water was fine before I went to bed)
  • called my well man and he wants to charge me the same price if the pump had went out and will not warranty his work
  • i changed the pressure control switch and control box with no success
  • the tank did have water in it but no pressure
  • when i drained the tank there was no force behind it or no water would come out of the spigot
  1. I would like to know if my pump went bad again or if my pressure tank went bad?
  2. what other issues i might have caused this issue?

Welcome to the forums.

The pressure tank only serves to stabilize the system pressure and keeps the pump from short cycling. You can run a well without a pressure tank. In other words..... your pump creates the system pressure not the tank.

Ok then. Sounds like my pump has failed again.

How much of the pipe did they replace? If it’s galvanized steel and is starting to develop holes, maybe another section of the pipe has sprung a big leak. Seems unlikely that the pump would fail after only a few months.

Bladder tank?
Is there Air in the top part? and does it hold?

Will the pump get up to shut off pressure?

If it does how long?

no air in the top part and no pressure. not sure if its a bladder style. the pump doesn't get to shutoff pressure now.

If the system doesn't get to shut off pressure than the pump is not pumping correctly or there is a leak between it and your tank.

If I’m not mistaken I think the major part of the cost is to pull the deep well pump itself, not just the cost of a new pump. But I don’t know what he means when he says he won’t warranty his work. It does seem like the only thing you can do, unfortunately, is to have the pump pulled up to see if there is a leak somewhere in the piping and also to determine whether the pump is working. At least that’s the way it seems to me.

But if a pro does this you would think he absolutely would find out what the problem is and be able to fix it. Don’t know what he means by no warranty.

I think the problem could be a leak from the pressure tank out to where the pipe goes down into the well. In other words, on the horizontal pipe buried under ground. Maybe you should look outside and see if you see and wet spots on the ground (happened to me once) if you haven't already done that.

Ok then. I will check out the piping that goes to the pump and the pump itself. As for the well repair man from what he told me if the pump had been damaged again then he would charge me the whole amount again($1500) to pull the pump and replace it. My argument with him was that I understand that labor is a part of the job and I was willing to pay him the cash to pull and reinstall the pump but not pay him for another pump if it's under warranty. That's where our disagreement came into play. Not worried anymore. I don't have a device yet to pull the piping and pump out but I did see something on YouTube on how a guy pulled his piping and pump out. Just curious if there is a better design on here or not. I didn't see anything.

I think you can rent devices like this, although I have never used one myself. Looks good, however. But maybe its not as easy as it looks. In the video the pipe is black poly but the same device is supposed to work on galvanized steel pipe.
