First, I am a city baby, never had well water. We now have well water, the well is far away from the house, out in the yard. Next to the house, with the water softener, tanks/equipment is a motor bolted on to a concrete slab. Is this the well pump? Lately there are periods when we have no water in the house. My husband has found that by going outside and giving this motor a good whack, it turns on, we get water. Our water person suggested we replace a switch from Home Depot. Relatively easy to put on, just wires and a pressure tube. Worked for a week or two, no whacking. Now back to whacking it every two days or so. Obviously dying, want to get it fixed before it does, BUT WHAT IS IT?? Can I buy this a HD? Should we call a plumber or electrician? Should we move back to the city? HELP!!!!
