I'm at my wits end...I've replaced a 1 1/2hp 3 wire franklin pump motor 2 times in the last 3 years. once i replace it, it runs great all summer and occasionally in the winter when I get up there but when i return in the spring it won't start...The well is 375 ft. with pleanty of water. The wire is #10 three wire. Last time it went I installed a check valve every 100 ft as recommended but still no help. Thank God I have a neighbor with an "UPZ Daisy" I'm becoming a pro at pulling well pumps. Help!
