Complete Well Water Maintenance Schedule: Monthly, Seasonal and Annual Tasks for Well Owners

A well is a long-term investment in your home’s water supply — but only if you maintain it. Unlike municipal water, you’re the utility company for your own water system. This comprehensive schedule breaks down exactly what to do, when to do it, and why it matters.

Monthly Checks (15 Minutes Total)

Water Quality Assessment

Visual inspection: Run the cold water tap for 30 seconds and check for discoloration, cloudiness, or sediment
Odor check: Smell the water for sulfur (rotten egg), metallic, or chemical odors
Taste test: If it tastes different from usual, test immediately and consider bottled water until you know why
Document: Note any changes in a maintenance log. Patterns emerge over time and can signal problems before they become emergencies

System Pressure Check

Watch the pressure gauge when the pump kicks on. Normal range: 30-40 psi for the cut-in, 50-60 psi for the cut-off
If the pump runs continuously without building pressure, you may have a leak, a failing pressure tank, or a pump issue
Listen for short-cycling (pump turns on and off every few minutes) — this indicates a waterlogged pressure tank

Visible Inspection

Walk the exterior of the wellhead. Look for cracks in the casing cap, corrosion on fittings, or standing water (which could indicate a surface contamination risk)
Check the electrical panel feeding the pump for signs of overheating or burnt connections
Verify the well pit (if accessible) is dry and free of debris

Quarterly Checks (30 Minutes Total)

Pressure Tank Inspection

Tap the tank with a metal object. If it sounds hollow at the top and solid at the bottom, the air bladder is working correctly. If it sounds solid throughout, the tank is waterlogged and needs service
Check the air charge with a tire gauge at the tank’s valve stem. It should read 2 psi below the pump’s cut-in pressure (typically 28 psi for a 30/50 switch, 38 psi for a 40/60 switch)
Drain the tank’s sediment filter if you have one

Well Field Inspection (for private wells with a well field)

Clear vegetation within 10 feet of the well head
Check that the grading slopes away from the well to prevent surface water accumulation
Inspect the sanitary seal for cracks or gaps

Water Testing (Alternate months)

Test for bacteria (total coliform and E. coli) every quarter during spring and summer
Test for nitrates, nitrites, and arsenic annually or every two years
Consider testing for your region’s common contaminants (radon in the Pacific Northwest, fluoride in the Southwest, etc.)

Seasonal Tasks

Spring (March-May)

Well and Pump:

Inspect the well head and casing for winter damage — frost heave can shift and crack well components
Check for flooding around the well cap and remove any standing water
Test water temperature — a sudden change may indicate surface water infiltration
Replace pressure tank air charge if it dropped below the target during winter
Flush your water system: run each faucet for 10-15 minutes to flush winter stagnation from pipes

Water Quality:

Post-Spring rain monitoring: after heavy spring storms, test water for bacteria and turbidity
If you tested bacteria quarterly, get a professional lab test at least once per spring

Landscaping:

Ensure spring rains haven’t created drainage issues around the well
Check that fertilizers and pesticides haven’t been applied within 50 feet of the well (a 50-foot minimum setback is recommended by most health departments)

Summer (June-August)

Well and Pump:

Increase pump runtime monitoring — summer drought can lower the water table and cause the pump to work harder
Check that the pump isn’t running longer hours than usual (which indicates low water conditions)
Verify the well pit ventilation is adequate (the pump motor needs airflow to stay cool)

Water Quality:

Monitor for algae growth in any above-ground storage tanks — summer heat accelerates algae
Test for bacteria monthly during peak usage months
If you’re using a water softener, check the salt level more frequently with increased usage

Preventive:

Clean or replace any sediment filters at the well head
Inspect the weatherhead on the pump wiring for water intrusion (humidity and storms are peak season)

Fall (September-November)

Winter Preparation (Critical):

Insulate exposed pipes and the well head. Use foam pipe insulation or heat tape on all outdoor plumbing
Check the well pit heater if you have one (a small heater prevents the pit from freezing)
Verify that the sanitary seal at the top of the well is intact — cold air and ice can enter through a compromised seal
Clear fallen leaves and debris from around the well head to prevent drainage issues
Test your sump pump if you have one (prevents basement flooding when snow melts)

System Checks:

Replace pressure tank air charge one final time before winter
Drain and winterize any outdoor faucets
Inspect the pressure switch and control box for moisture or corrosion

Water Quality:

Get a comprehensive professional water test before winter. This is your baseline for the cold season
Test for bacteria, nitrates, nitrites, arsenic, lead, copper, and your regional contaminants
If your well has been contaminated during the year, consider installing a whole-house UV treatment system before winter

Winter (December-February)

Monitoring (Minimal Physical Work):

Monitor water usage closely. Frozen ground means less recharge and a lower water table — use less water until spring thaw
Listen for the pump running longer or more frequently than usual, which indicates the well is struggling
Check for ice buildup around the well head and clear it immediately
If water pressure drops suddenly, the pump may be pulling air — shut it off and investigate

Emergency Preparedness:

Know how to shut off your well pump in an emergency
Have a backup water source or storage plan for winter emergencies
Keep a water heater element inspection schedule — winter ice can damage your home’s water heater too

Annual Tasks

Comprehensive Well Inspection

Hire a licensed well contractor for a professional well inspection every 3-5 years minimum. They’ll check:

– Well casing integrity (no cracks or corrosion)

– Annular seal condition (the grout between the casing and the borehole)

– Pump performance (flow rate, voltage, amperage)

– Well screen condition

– Water level (static and pumping levels)

Water Treatment System Maintenance

Service your water treatment system per the manufacturer’s schedule (UV lamps need annual replacement, filter media needs periodic backwashing, salt systems need cleaning)
Replace whole-house sediment filters at least annually
Test water treatment system output to confirm it’s working correctly

Electrical System Check

Have an electrician check the pump wiring, control box, and connections annually
Look for signs of insulation breakdown, corrosion, or overheating
Test the grounding and bonding of the electrical system

Well Casing Integrity

Check the well cap for cracks, corrosion, or missing bolts
Verify the sanitary seal is intact
Inspect the concrete pad or apron around the well head for cracks or settling (a 2-4 foot concrete apron sloping away from the well is ideal)

Water Quality Full Panel Test

Full comprehensive lab test every 1-2 years minimum
Core tests: bacteria, nitrates, nitrites, arsenic, lead, copper, iron, manganese
Regional tests based on your geology (radon, uranium, fluoride, pesticides, etc.)
Keep records of all test results — they’re valuable for tracking water quality trends and for property transfers

Decades-Long Maintenance

Every 5 Years

Consider pumping the well to remove accumulated sediment at the bottom (well development)
Inspect and potentially replace the pressure tank (they typically last 10-15 years)
Re-certify your well permit if required by your state (some states require periodic re-inspection)

Every 10-15 Years

Plan for pump replacement (the pump is likely near the end of its life if it’s been more than 10-15 years)
Consider well rehabilitation to improve flow rates
Re-evaluate the well’s depth and production capacity as the water table may have shifted

What Not to Do

Never allow chemicals, fuels, or pesticides near the well head — even a small spill can contaminate your entire water supply
Don’t ignore changes in water quality — a gradual change is often more concerning than a sudden one
Don’t skip annual testing — many contaminants are colorless, odorless, and tasteless but dangerous
Don’t try to dig or modify the well casing yourself — only licensed well drillers should work on the well itself
Don’t use bleach to “clean” your well — this is a myth and can damage your plumbing, septic system, and water quality

No water at all (check breaker first, then pressure switch, then pump)
Water table dropping noticeably
Neighbors drilling deeper wells (indicates regional water table decline)
Flooding or surface water entering the well head area
Positive bacteria test result

Regular well maintenance doesn’t have to be complicated or time-consuming. The monthly checks take 15 minutes. The quarterly checks take 30 minutes. The seasonal work is mostly observation and preparation. The annual professional inspection is an investment that saves you thousands in emergency repairs.

A well-maintained well is a quiet well. If you’re constantly aware of your well because something seems off, that’s your cue to act. Most well problems are preventable with consistent, scheduled maintenance.
