- [Shallow Well Pump and Pressure Tank Sizing Is Site-Specific](https://www.oldsteamers.com/blog/shallow-well-pump-with-pressure-tank): Roughly 25 vertical feet from pump to water level is a screening guideline, not guaranteed capability. Sizing uses pump curves, usable drawdown and runtime.
- [Signs of a Well Drying Up vs. Equipment Trouble](https://www.oldsteamers.com/blog/signs-of-well-drying-up): Failure under heavy demand and improvement after rest suggest drawdown or low yield. Water-level measurements and system inspection are needed to confirm the cause.
- [Well Pump Maintenance: Observe, Then Act on Changes](https://www.oldsteamers.com/blog/well-pump-maintenance): Track normal pressure, flow and cycling. Investigate changes rather than adjust controls, and test annually for total coliform and E. coli.
- [A Float Level Switch Must Match the Application](https://www.oldsteamers.com/blog/float-level-switch): The liquid must lift the float, wetted parts must tolerate the process, movement needs clearance, and the contact must suit the control circuit.

- [Well Pump Failure Signs Can Come From Other Components](https://www.oldsteamers.com/blog/signs-of-well-pump-failure): Repeated breaker trips, humming without water delivery or a running pump that does not raise pressure need prompt checks of the pump, motor, wiring and controls.
- [Four Clues Narrow Down a Well Water Pump Problem](https://www.oldsteamers.com/blog/well-water-pump-not-working): Compare whole-house flow, breaker status, gauge behavior and pump sound. Reset a tripped breaker once only if the panel is dry, undamaged and safe to access.
- [How to Prime a Pump Based on Type and Setup](https://www.oldsteamers.com/blog/how-do-you-prime-a-pump): For surface water pumps isolate power, add water at the approved point and vent air. A steadily falling level suggests a suction leak or nonholding foot/check valve.
- [Well Pump Capacitor Replacement Is Model-Specific](https://www.oldsteamers.com/blog/well-pump-capacitor-replacement): Matching microfarads alone does not establish compatibility. Catalogs distinguish type, voltage, resistor configuration, control-box application and pump rating.
- [What to Check When Your Well Pump Stops Working](https://www.oldsteamers.com/blog/well-pump-stopped-working): First check whether every fixture is affected, then note the gauge and pump sounds. Reset a tripped breaker once only if no danger signs are present.
- [8 Pump Pressure Switch Specs to Check](https://www.oldsteamers.com/blog/pump-pressure-switch): Familiar housing and a nominal pressure range do not prove compatibility. Voltage, motor rating, port and wiring still matter. Gauge behavior can flag system faults.
- [What Is Claverton Pumping Station?](https://www.oldsteamers.com/blog/claverton-pumping-station): Flowing river water powers the mechanism that lifts a separate flow approximately 48 feet. Its six stages show what the wheel, beams and pumps each do.

- [Check Valve and One-Way Valve Cover Many Designs](https://www.oldsteamers.com/blog/check-valve-one-way-valve): A check valve is a one-way valve, but reliable service still requires matching the medium, flow range, cracking pressure, orientation and closure dynamics.
- [How a VP44 Injection Pump Fails and What to Check](https://www.oldsteamers.com/blog/vp44-injection-pump): Measure supply pressure at the VP44 inlet: aim for 12-15 psi at idle and never below ~10 under load instead of assuming pressure from a new-part receipt.
