I have a 1 1/2 HP Gould jet pump and the motors only last for about 2 years. It was installed when we built the house in 1999. The first motor locked up and burned out in about 2 1/2 years. I have replaced the motor for another 2 years and then replaced the bearings on the second motor once. It seems like I get about 2 years and then have motor problems. I now have a noisey motor again and will replace or rebuild soon. I've been told that a motor should last about 10 years. Any ideas?
The pump supplies water for my house and lawn irrigation. The well is 131 feet deep. In the house it's just my wife and I. I live in South Florida so the irrigation part is mostly in the spring until the summer rains come. The pump sits outdoors on a concrete slab.
