What is a Private Well?
A private well is a water supply system that draws groundwater from an aquifer to serve a single household or property. Over 15 million households in the United States rely on private wells for their drinking water, particularly in rural areas not served by municipal water systems.
Unlike public water supplies, private wells are not regulated by the EPA. This means you are responsible for ensuring your water is safe to drink. Regular testing and maintenance are essential for protecting your family's health.
Well System Components
Understanding your well system helps you maintain it properly and troubleshoot problems. A typical private well includes:
The Well Casing
A pipe (usually steel or PVC) that lines the well hole and prevents contamination from surface water. The casing should extend at least 12 inches above ground level.
Well Cap or Seal
A sanitary seal at the top of the casing that prevents insects, debris, and contaminants from entering the well. This should be inspected regularly for damage.
Well Pump
Moves water from the well to your home. Most modern wells use submersible pumps located deep in the well, while older or shallow wells may use jet pumps above ground.
Pressure Tank
Stores water under pressure so the pump doesn't run every time you turn on a faucet. Typical pressure settings are 30-50 or 40-60 PSI.
Pressure Switch
Automatically turns the pump on when pressure drops and off when the tank reaches full pressure.
Water Testing Schedule
Regular water testing is the most important thing you can do to ensure your well water is safe. The CDC and EPA recommend these testing frequencies:
Annual Testing (Every Year)
- Total coliform bacteria - Indicates possible contamination
- Nitrates - Especially important if infants use the water
- pH level - Affects pipe corrosion and water quality
- Total dissolved solids (TDS) - Overall water quality indicator
Test More Often If:
- Water changes in taste, odor, or color
- Pregnant women or infants in the household
- Nearby land use changes (new construction, farming)
- Well repairs were recently made
- Flooding occurred near the well
Where to Get Water Tested
Contact your local health department or state environmental agency for certified testing labs. Expect to pay $25-$150 per test depending on what you're testing for.

Your well pump is the heart of your water system. With proper care, pumps can last 10-15 years or longer.
Monthly Checks
- Pressure gauge - Should read between 40-60 PSI
- Listen for cycling - Pump shouldn't turn on/off rapidly
- Check for leaks - Around pressure tank and pipes
Signs of Pump Problems
- Reduced water pressure throughout the house
- Water spurts or air in the lines
- Pump runs continuously
- Clicking sounds from the pressure switch
- Higher than normal electric bills
- Visible rust or sediment in water
When to Call a Professional
Well pump repairs require specialized equipment and expertise. Call a licensed well contractor if you notice persistent problems or need to pull the pump for service.
Seasonal Maintenance
Spring
- Schedule annual water testing
- Inspect well cap for winter damage
- Check for low spots that might flood near the well
- Clear debris from around the wellhead
- Ensure proper drainage away from the well
Summer
- Monitor water level during dry periods
- Watch for signs of overuse (dropping pressure)
- Keep lawn chemicals away from well area
- Maintain 50-foot clearance from chemical storage
Fall
- Prepare for winter (see winterizing below)
- Check condition of well cap and seal
- Remove any vegetation growing near casing
- Document your well's location for winter access
Winter
- Insulate exposed pipes above the frost line
- Insulate the pressure tank if in unheated space
- Keep cabinet doors open under sinks in cold snaps
- Know how to shut off water in case of frozen pipes
Warning Signs Your Well Needs Attention
Water Quality Issues
- Cloudy or murky water - Possible contamination or sediment
- Rotten egg smell - Sulfur bacteria or hydrogen sulfide
- Metallic taste - Pipe corrosion or high iron content
- Staining - Iron, manganese, or other minerals
System Performance Issues
- Pressure drops when multiple fixtures are used
- Air spurting from faucets
- Pump cycles on and off frequently (short cycling)
- Pump runs but no water comes out
- Unexplained increase in electric bills
Physical Issues
- Cracked or damaged well cap
- Standing water around the wellhead
- Well casing visible above ground is damaged
- Leaks at pipe connections
Maintenance Costs
Understanding typical costs helps you budget for proper maintenance:
Routine Maintenance
- Water testing: $25-$150 per test
- Well inspection: $150-$300 annually
- Pressure tank service: $100-$200
Repairs
- Pump replacement: $1,500-$3,000 (including labor)
- Pressure tank replacement: $500-$1,200
- Well cap replacement: $100-$300
- Shock chlorination: $150-$300
Major Work
- Well rehabilitation: $2,000-$5,000
- Drilling a new well: $5,000-$15,000+
Regular maintenance costing $200-$400/year can prevent expensive repairs.

Frequently Asked Questions
How often should I test my well water?
Test your well water at least once per year for bacteria and nitrates. Test more frequently if you notice changes in taste, odor, or color, or if anyone in your household becomes pregnant or there are infants in the home.
How long does a well pump last?
A submersible well pump typically lasts 10-15 years with proper maintenance. Jet pumps may last 8-10 years. Regular maintenance and avoiding running the pump dry can extend its lifespan.
What are signs my well pump needs attention?
Warning signs include reduced water pressure, water that spurts from faucets, higher electric bills, pump running constantly or cycling frequently, and unusual noises from the pump.
How deep should a private well be?
Well depth varies by location and aquifer depth. Shallow wells are less than 50 feet, while deep wells can be 100-400 feet or more. Deeper wells generally provide more consistent water quality and quantity.
Can I use pool shock to chlorinate my well?
No. Pool shock contains additives that are not safe for drinking water. Use only unscented household bleach (sodium hypochlorite 5.25-8.25%) or chlorine granules specifically designed for well treatment.
