Another well question

[MadReferee]

I have a 4" Goulds submersible 2-wire pump (3/4hp I think). Life expectancy is 7-10 years for typical residential use and that is about what I get out of my pumps. As was earlier said, cycle times and water quality will play a factor in pump life.

A resistance check of a motor doesn't tell anyone very much, unless it's an open circuit. An insulation test of the windings doe's tell a lot!
Then a current test with an ammeter tells almost the whole story.

Mines a one and a half horse at 500 feet depth, should show 10 amps when running.

The pump guy probably was checking insulation, which maybe was starting to show low! If so, the pumps seals have failed, allowing water to enter the windings.

This is unrelated I think to your particular problem. But Id like to add something to the subject of pump problems.In cases some come here and can use it.
If the pressures go haywire,alwasy chect the pressure switch diaphram end for crude, and the nipple that feeds it.
I just wanteds to pass this along, as my neightbor spent an unbelievable amount of money with a well company, and come to find out it was crud buildup.
Good Luck

I thought they were checking for dead short or water infiltration with the resistance test Goulds listed. I'm a lay guy on electric so maybe I'm /forums/images/graemlins/confused.gif. Nothing new in that. They were testing motor leads to ground as I recall. My thinking was that water present in the wrong area would change the values?

Wonder why they don't just throw an ampmeter on it? Maybe cause it's harry homeowner reading the brochure and he ain't got one? /forums/images/graemlins/grin.gif

Thanks for all the replies. Guess I'll go ahead and replace the pump. Just don't know enough about the issue to have a real comfort level with it but can't do without water.
