Thanks for the reply, Speedbump. Sure wish I was on this site back in 'those' days! I needed it more back then....

The third time PE was used and mandated the use of a poly rope for future removal.

It sounds like a homeowner put this submersible pump in. Pro's don't use rope. You either have a broken, cracked or pin holed pipe down the well. Or the pump ran dead head and nuked the impellers. If it happened slowly over time, chances are you have pinholes. However I don't know why anyone would use rope with galvanized pipe.
By changing the pressure switch, you may not have really accomplished anything unless you saw water coming out of the tube the switch connects too. Sulphur in water can sometimes completely cover up an opening in the pipp where that tubing connects and not allow the switch to see the pressure changes. If this hole covers over completely when the pump is running, it will keep running until it melts impellers.

Consult with your building department to see when the pump was changed last and by whom.
A permit is usually required for any domestic water equipment. You might try the company that drilled your well as well.
They all keep records [or should be!]
If there is a lot of silt being pumped up in the casing, it could be jamming your pump in the casing.
Machinery can be used for real deep wells as the combined weight could be a problem.

If there isn't then I would suspect either the pump itself, in the case of a multi-stage pump or a clogged or stuck foote valve.
If it is the foote valve, the whole pump and pump line has to be removed from the casing. I have no idea how deep your well is, but all that discharge piope needs to be removed.

I went outside to the well and I see that a rope is tied to something deep down there. I slightly yanked and it feels like it wouldn't budge even if I pulled hard. To pull this out and test it, would it require a machine and two people? Thanks again

you said you replaced the switch. which switch?? why did you replace the switch?
do you have a vertical "goulds" tank? is there a schrader valve on top of the tank [ looks like a tire valve]
a top valve means there is an air bladder inside the tank. it could have burst - you won't know unless the pump cycles on-off quite frequently.
outlet pressure should be in the 40-45 lb range.
Thanks for your help HayZee

Extremely low water pressure from well pump
Hello -
My mother has a well pump and has been complaining that the water pressure has gradually been getting lower so I decided to look at it. First thing that I noticed is that the pressure gauge is stuck on 20 PSI....it has yet to move after days. I released all the water from the tank and replaced the switch. No change. The switch is stuck with the contacts touching but the gauge does not move. What could this be? By banging on the tank, the bottom has a thug while the top is a hollow sound (That eliminates the tank right?) Is the well pump bad? How do I confirm this?
Thanks for your helpTags: None
