House built 1971. I bought in 1983. Michigan year around lake front home. Well on lake side 53' deep Red Jacket pump. Level to house within 25'. Unless it had service before I bought the house the pump has never been out. I have replaced the control box 1 time and am on the second tank. Original galvanized now a weltrol type. Took off outside cap with no trouble. 6 weeks ago pump was cycling every 5 minutes.Shut off valve to house.I concluded it to the well drop pipe casing or checkvalve. While house valve was closed and pump was refilling the tank at shut off it would hammer a couple bumps.This seemed to possibly rattle the check valve because it then started to cycles every 40-60 minutes. It has recently started cycling every 20 minutes. I was going to add a check valve where it comes in the house but after reading the thread on that it doesnt sound wise. To get a truck to my well Id have to take out a tree and have serious lawn work done. One guy said he'd use a car jack and block it up and try to pull it that way. Another said he had a Pull a Pump.Is one better than the other? If thats sucessful and all we needed to do was replace the check valve would you recommend everything be replaced? One guy said just do the check valve another said replace it all except the casing screen and pitless adapter but maybe the o ring on it. If that failed and a truck was necessary should I just bite the bullet and do it all right now considering its age?. FWIW I just replaced my A.O.Smith hot water tank after 37 years too if thats any indication on what type of water I have. I also was cnsidering the VFD pump but now Ive read about the CSV Im likely to go for that. Another question Red Jacket or Grundfus I like the 3 wire idea because of the location of the control Thanks Jon
