How much does well maintenance cost per year?

Basic annual maintenance costs $150–$400: water quality test ($30–$80), well inspection ($100–$300), and minor supplies. Treatment system maintenance (filter changes, salt) adds $50–$200. This prevents emergency repairs that cost $1,000–$5,000+.

What maintenance can I do myself?

You can visually inspect the well cap (check for cracks or damage), check pressure tank air charge (with a tire gauge), clear vegetation from the wellhead area, and monitor for changes in water quality. Leave electrical work, pump service, and well disinfection to a licensed contractor.

Well Maintenance Schedule: Annual Checklist for Homeowners

Q: How often should I have my well inspected?

Have a certified well contractor inspect your system once per year. The inspection should cover the well cap, casing, pressure tank, pump performance, and electrical connections. Cost: $100–$300. Annual inspections catch small problems before they become expensive failures.

Most well problems are preventable. A simple annual schedule keeps your water safe and your equipment running longer^[1].

This checklist covers everything: testing, inspections, and seasonal tasks. Print it. Stick it on the fridge.

Quick Answer

Test water quality once per year (bacteria and nitrates at minimum). Get a professional well inspection once per year. Check your pressure tank and well cap every 6 months. Total annual cost: $150–$400^[2].

Annual Maintenance Schedule

Task	When	Cost	DIY?
Water quality test (bacteria + nitrates)	Every year	$30–$80	Sample collection: yes. Lab analysis: send out.
Professional well inspection	Every year	$100–$300	No. Use a certified contractor.
Pressure tank check (air charge + visual)	Every 6 months	Free	Yes. Use a tire gauge.
Well cap & casing inspection	Every 6 months	Free	Yes. Visual check.
Treatment system maintenance	Per manufacturer schedule	$50–$200/yr	Usually yes.
Full water panel (iron, hardness, pH, TDS, arsenic)	Every 3–5 years	$80–$200	Send to lab.
Well sanitization (shock chlorination)	As needed	$100–$300 (pro)	Possible. Guide here.

Analyze My Water Test

Spring Checklist

Inspect the well cap. Look for cracks, gaps, or a loose fit. A damaged cap lets insects, rodents, and surface water into your well^[3].
Check for standing water around the wellhead. Water should drain away from the well, not pool around it. Regrade soil if needed.
Test water quality. Snowmelt and spring rain increase bacteria risk. Test for coliform and nitrates^[4].
Service treatment equipment. Replace sediment filters. Check salt level in softeners. Clean UV lamp sleeves.
Clear vegetation. Keep bushes, trees, and grass trimmed at least 3 feet from the wellhead.

Summer Checklist

Monitor water level. Hot, dry summers can lower the water table. Watch for air sputtering or pressure drops — signs the pump is near the water level.
Check pressure tank performance. Tap the tank. The top should sound hollow (air) and the bottom full (water). If it sounds full everywhere, the bladder may have failed.
Conserve water during drought. Stagger heavy water use (laundry, irrigation). Let the well recover between uses.
Inspect for signs of well problems. New staining, taste changes, or pressure drops warrant attention^[5].

Fall Checklist

Schedule your annual water test. Fall is a good time — results arrive before winter when accessing labs is harder.
Schedule your annual well inspection. Contractors are less busy in fall than spring^[2].
Check surface drainage. Rake leaves and debris away from the wellhead. Make sure the ground still slopes away from the well.
Watch for tannin spikes. Fall leaf decomposition can increase tannins in shallow wells.
Pre-winter treatment check. Replace filters and UV lamps before cold weather makes access difficult.

Winter Checklist

Insulate exposed pipes. Any pipe above ground or in unheated spaces needs pipe insulation or heat tape^[6].
Protect the well house. If your pressure tank is in a well house, ensure it has a heat source (heat lamp, space heater with thermostat). Set to 40°F minimum.
Monitor for freezing. If water flow stops or slows in extreme cold, pipes may be frozen. Never use an open flame to thaw — use a hair dryer or heat tape.
Check pressure tank. Cold weather makes pump cycling problems more obvious. Rapid cycling = tank issue.
