Annual Maintenance Checklist
Every year, well owners should complete these essential maintenance tasks:
- Test water quality: At minimum, test for coliform bacteria and nitrates ($50–$200). This is the single most important maintenance task.
- Inspect the wellhead: Check that the well cap is secure, the casing is intact, and there is no standing water around the wellhead. The ground should slope away from the well.
- Check pressure tank: Verify the air pressure (should be 2 PSI below the pump cut-in pressure). Waterlogged tanks cause rapid pump cycling and premature pump failure.
- Monitor for changes: Keep track of water pressure, flow rate, and water appearance. Changes can indicate developing problems.
- Check electrical connections: Inspect the pump control box, pressure switch, and wiring for signs of corrosion, overheating, or damage.
Signs Your Well Needs Attention
Do not ignore these warning signs, early attention prevents expensive repairs:
- Sputtering or air in the water line, may indicate a failing pump, drop in water level, or cracked pipe
- Reduced water pressure, could be a pump issue, clogged filter, or mineral buildup in pipes
- Muddy or sandy water, suggests well screen failure or sediment entering the well
- Pump running constantly, indicates a leak, failed pressure switch, or waterlogged pressure tank
- High electric bills, an inefficient or failing pump draws more power
- Visible damage to wellhead, cracks, missing cap, or standing water around the casing compromise your water quality
- Change in taste, color, or odor, could indicate contamination, mineral changes, or bacterial growth
Well Rehabilitation
Over time, mineral deposits, bacteria biofilm, and sediment can reduce your well's yield. Well rehabilitation (cleaning) costs $500–$3,000 and can restore flow rates to near-original levels. Techniques include:
- Chemical treatment: Acids or chlorine solutions dissolve mineral deposits and kill bacteria ($500–$1,500)
- Mechanical brushing: Wire brushes scrub the well screen and casing ($800–$2,000)
- Hydrofracturing: High-pressure water injected into the well fractures surrounding rock, opening new water pathways ($2,000–$5,000)
- Surging and jetting: Pulsing water loosens sediment and deposits from the well screen ($500–$1,500)
Maintenance FAQ
How much does well maintenance cost per year?
Routine annual well maintenance costs $200–$600, covering water quality testing ($50–$200) and a basic inspection ($100–$300). Every 3–5 years, add $150–$400 for pump servicing. Major items like well rehabilitation ($500–$3,000) and pump replacement ($1,500–$5,000) are periodic costs over the well's 30–50 year lifespan.
How long does a well last?
A properly maintained drilled well lasts 30–50 years. The well casing and bore itself can last 50+ years. The pump is the component most likely to need replacement, typically every 10–25 years. Driven wells last 15–25 years, and dug wells last 10–20 years.
