i came across a new site called gouldswellpumps.org and maybe you will find the answer on there as it is all about goulds well pumps and submersible well pumps
In very clean wells I have seen submersible pumps 18-20 years old. Unfortunately any degree of silt lessens the life of pumps and I would guess the average to be about 14 years.
The water should be added last. All the aggregate materials and the cement should be thoroughly mixed before the water is added.
i don't know how long a water pump should last, but mine just went out on my 2005 TB at 47,000 miles. ugh.
you should have a lvl 50 water type
That depends on how much water is drawn from the tank and how often it is drawn.
Flush it away with water.
As the last resort
Gould is a variant of the name Gold which originates from Jewish. The surname Gould originates from several cultures: Irish, English, Scottish, and Jewish. It is not from entirely one culture or another. All of the English (Irish or Scottish) Goulds are not necessarily of Jewish origin.
Between 60 weeks and 120 weeks depending on water quality
They should be replaces every 5 years to ensure energy savings.
They will last up to 3 months in salt water but they need to remain chilled so i would also keep them in the refrigerator.
