Good evening,
I apologize that my first post is a question. I have been on the Google most of the day and I landed here. I did more searching and hit a wall so I am here requesting help.
Problem:
Pressure tank leaks down and cycles submersible pump every 4.5 min.
Configuration:
95’ well in 4” casing.
Grundfos 1/2HP pump 21’ from top of casing cap. Pump installed January, 2007
Control box also installed at the same time.
Pump on the end of 21’ galvanized 1” pipe
Plastic to house
Pressure tank 20gal. Bladder in-tact and charged to 30psi
On at 30 and off at 50.
History:
The original pump installed 1977. It lasted until 2007.
2007 the original pump failed and was replaced with the current Grundfos 1/2HP pump and new 1” galvanized pipe.
2010 the exact same symptoms as now (pressure tank bleeds down to continuously cycle pump).
The pump was pulled and problem identified a hole in the galvanized pipe that was installed 3 years earlier. I saw a spout of water from the pipe as it was pulled from the casing.
The pipe was replaced with another galvanized pipe and the problem was fixed, until this week.
Today:
The well service is coming Friday
Oberservations:
The well service seems to think there is some sort of electrical problem that is causing the pipe to develop holes. I think I heard “transient voltage” at some point in the replacement process.
The well service thinks I should get an electrician to check ?????
And that is the problem; I don’t even know what I am supposed to ask the electrician to check.
And the other thing is that the first pump lasted 30 years and the pipe was not compromised, the pump just gave up.
The wiring in the house has not changed.
The wire from the cap to the pump was replaced when the pump was replaced.
Our house is properly grounded.
You would think that the pipe should last more than 6 years (and that is assuming this is the same problem).
My questions:
-Does anyone know what the well service is trying to tell me about electrical effecting the corrosion of the pipe?
-Is plastic pipe an option?
-How about stainless steel?
We have pretty corrosive water. Is this just the way it will be?
Thank you for reading this, I know it got kind of long. I was just trying to be complete.
Any help is very much appreciated.
