Well Pump and Water System Repair: Pressure Tanks, Switches, Jet Submersible Pumps: Diagnosis, Repair, Quality Freeze Protection

Know what normal looks like, and every fault points to its cause. A 20 gallon pressure tank on a 40/60 switch delivers only about 5 gallons per cycle. This book explains why, and how every part of a private well water system works together: the pump, the pressure switch, the pressure tank, the valves and the piping. Then it teaches you to diagnose faults in a safe order, make the common homeowner repairs, test and treat your water, and protect the whole system from freezing and power cuts. Forty-eight lessons in eight parts How a Well System Works: the system in order, safety before you start, wells and casings, jet pumps, submersible pumps, pressure tanks. Controls and Pressure: the pressure switch, cut-in and cut-out, tank precharge, drawdown, pump cycling, check, foot and relief valves. Diagnosis: a step-by-step method, no water, low pressure, short cycling, a pump that will not stop, air and noise. Repair: replacing a pressure switch and a pressure tank, jet pump repairs, submersible service and wiring, check valves, voltage drop. Flow, Head and Sizing: measuring flow, pressure and feet of head, total dynamic head, well yield, tank sizing, pump curves. Water Quality: lab testing, shock chlorination volume, hardness, iron and sulfur, sediment filters, treatment equipment, records. Freeze Protection and Seasonal Care: where systems freeze, insulation, heat cable, winterizing, spring restart, an annual schedule. >Every lesson has a short explanation, the key rules in a box, two worked examples, a common mistake to avoid, a tip from the field and practice questions with answers. Also inside A step-by-step diagnosis guide for 10 common symptoms, with yes and no paths. 26 diagrams, including the pressure cycle, tank drawdown, total dynamic head and a storage system. 12 worksheets and 300 practice exercises, all with worked solutions. A 25-row troubleshooting table and 8 reference tables. >Safety comes first throughout: power off, locked and tested dead before any wiring; pressure released before any fitting; and clear guidance on which jobs belong to a licensed electrician, a well contractor or the health department. Every pressure, flow and chlorine figure in this book is an example; your equipment makers, local code and health department govern.
