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.
