How Do I Maintain My Water Well Pump?

Are you concerned about keeping your well pump reliable, efficient, and problem-free so you always have safe water when you need it?

How Do I Maintain My Water Well Pump?

Maintaining your water well pump is one of the best investments you can make in the reliability of your household water supply. Regular maintenance reduces emergency repairs, extends pump life, keeps operating costs down, and helps protect water quality. In the sections that follow, you’ll find a thorough, practical maintenance schedule, troubleshooting guidance, seasonal tips, safety precautions, and professional service recommendations to help you care for your well system with confidence.

Why regular maintenance matters

When you keep up with routine checks and preventive care, you avoid sudden pump failures, costly replacements, and potential contamination issues. You also preserve consistent water pressure and lower your energy bills. Think of maintenance as small, periodic investments that prevent much larger, disruptive problems later on.

Understand your well system

Before you begin any maintenance, it’s important that you understand what components make up your system and how they work together. Familiarity helps you spot problems early and decide when a professional is needed.

Main components of a typical residential well system

You’ll commonly find the following parts:

• Well casing and cap: The pipe that lines the well and the sealed cap that keeps contaminants out.
• Pump: Submersible pump (most common for deeper wells) or jet/jet-assist (for shallow wells).
• Pressure tank: Stores water to reduce pump cycling and maintain steady pressure.
• Pressure switch: Controls when the pump turns on and off.
• Check valve and foot valve: Keep water from flowing back into the well.
• Pipes and fittings: Deliver water from the well to your home.
• Electrical controls and wiring: Power the pump and control devices.
• Water treatment equipment (if installed): Filters, softeners, UV systems, etc.

Types of pumps and how that affects maintenance

You’ll typically have one of the following:

• Submersible pump: Installed below water level in the well; needs less surface space but requires attention to electrical connections and motor performance.
• Jet pump (above-ground): Easier to access for repairs but less efficient for deep wells.
• Shallow well pump: Simpler and cheaper but only suitable for shallow water tables.

Each type has maintenance nuances. For example, submersible pumps require a professional for most repairs, since they’re down the well, while jet pumps are more serviceable at the surface.

Routine maintenance schedule (what to do and how often)

A consistent schedule helps you track tasks and maintain a healthy system. Use the table below as a guideline. Adjust frequency based on your system’s age, usage, water quality, and local conditions.

Monthly checks: the easy things you can do

Do these quick checks every month to catch problems early:

• Turn on faucets and notice any reduction in pressure or sputtering.
• Listen at the pump and pressure tank for new grinding, rattling, or humming sounds.
• Look for wet ground, unusual odors near the wellhead, or insect/animal intrusion.
• Keep the well area clear of vehicles, chemicals, and heavy equipment.

Seasonal maintenance

Seasonal tasks prevent weather-related problems:

• Fall: Insulate exposed pipes, secure the well cap, and ensure surface drainage directs water away from the well.
• Winter: Apply freeze protection to exposed components; keep an eye on heat sources if the well house is heated.
• Spring: Check for contamination after runoff or flooding; replenish any rodent-proofing or seals that may have been damaged over winter.

Water testing: protect your health

You’re relying on the well for safe drinking water, so water testing is essential.

What to test for and when

• Annually: Test for total coliform and E. coli bacteria and for nitrates (especially if you have young children, infants, or expectant mothers).
• Every 2–3 years: Test for pH, hardness, iron, manganese, chloride, and total dissolved solids (TDS).
• As needed: Test for volatile organic compounds (VOCs), pesticides, or heavy metals if there’s local concern from industry, agriculture, or local contamination sources.
• After repairs or emergencies: Test after well repairs, flood events, or if you notice changes in taste, odor, or appearance.

How to get samples tested

• Use a certified lab, often recommended by your local health department.
• Follow sample collection instructions exactly to avoid contamination.
• Keep records of test results and dates for trend analysis.

Pressure tank and pressure switch maintenance

The pressure tank and pressure switch are the heart of steady water pressure and pump protection.

How the pressure tank works

The tank stores water and air so the pump doesn’t need to run each time you use a small amount. Maintaining the correct air charge (precharge) prevents short cycling and premature pump wear.

What you should check monthly/annually

• Monitor the pressure gauge on the tank.
• Listen for short cycling (pump turns on/off rapidly). That usually indicates a problem with the tank’s air charge or a leaking bladder.
• Annually, check the tank precharge: turn off the pump, drain water from the tank, and measure air pressure at the tank’s Schrader valve. The precharge should be 2 psi below the pump cut-in pressure (e.g., if cut-in is 30 psi, set precharge to 28 psi).
• Replace tanks when the bladder fails or when corrosion or leaks appear.

Pressure switch care

• Periodically remove the cover and inspect for corrosion, dirt, or loose wires (power off first).
• Clean and adjust the switch per manufacturer instructions. If the switch wears or the contacts are pitted, replace it.
• If the switch settings are changed, write down original settings before adjusting and test system operation afterwards.

Electrical and controls: safety first

Electrical failures are a common cause of pump problems. You can perform basic visual inspections, but call a licensed electrician or well specialist for electrical work.

What to inspect

• Check wiring at the pressure switch and control box for corrosion, burned insulation, or loose connections (power off).
• Look for tripped breakers or blown fuses at the home electrical panel.
• Monitor electrical bills and pump run time. A surge in energy use can indicate a failing motor or inefficiency.
• If you notice excessive motor heat, strange smells, or burning sounds, shut off power and call a professional.

Preventing contamination at the wellhead

Your wellhead is the first line of defense against contaminants.

Maintain the well seal and cap

• Ensure the cap is tight, sanitary, and vermin-proof.
• Replace cracked or damaged caps immediately.
• Grade the ground around the well so water drains away rather than toward it.
• Avoid storing chemicals, fuel, manure, or other potential sources of contamination near the well.

Surface sanitation

• Keep at least a 50–100 foot buffer between the well and septic systems, fuel tanks, livestock pens, and chemical storage (local codes may be stricter).
• Remove pesticide or fertilizer sprayers from the area when not in use.
• Make sure any well houses are sanitary and rodent-proof.

When and how to disinfect (shock chlorination)

Shock chlorination can remove microbial contamination from your well system, but it must be done carefully.

When to disinfect

• After a positive coliform/E. coli test.
• After well construction, repairs, or pump replacement.
• If flooding or surface contamination occurs.

High-level overview of the process

• Consult local health guidance or a professional if you’re unsure about concentrations or procedures.
• Turn off pump power and mix household bleach (sodium hypochlorite) with water to create a disinfecting solution.
• Introduce the solution into the well so disinfectant reaches the entire system including hot and cold lines, and storage tanks.
• Let the solution sit for several hours (often 6–24 hours), then flush until chlorine smell is minimal and retest the water before using it for drinking or cooking.

Important: Never mix bleach with other chemicals or cleaners (especially those containing ammonia), and always use protective gloves and eye protection. If you’re unsure about proportions or procedure, hire a licensed well contractor or contact your local health department.

Troubleshooting common problems

Knowing the symptoms and likely causes helps you decide whether to do a simple fix or call a professional. The table below summarizes common issues, likely causes, and recommended actions.

Tools and supplies you should have on hand

You don’t need an extensive toolbox, but the right items make routine tasks easier:

• Pressure gauge (portable) to verify system pressure.
• Air compressor or bicycle pump with a gauge for precharging tanks (if needed).
• Basic hand tools: adjustable wrench, screwdrivers, pliers.
• Multimeter for checking electrical continuity and voltage (use only if you’re comfortable with electrical work).
• Replacement parts: pressure switch, tank fittings, hose clamps, basic replacement tubing.
• Water test kits for preliminary checks (not a substitute for lab testing).
• Personal protective equipment: gloves, safety glasses, and appropriate footwear.

When to call a professional

You should contact a licensed well contractor or electrician when:

• The pump must be removed from the well (submersible pumps).
• You suspect motor failure, severe electrical problems, or need pump replacement.
• You detect contamination you can’t resolve with basic disinfecting.
• You need to re-drill, deepen the well, or perform a video inspection.
• You’re uncomfortable working around electrical components or dangerous chemicals.

Regular professional inspections every few years provide a deeper assessment of pump performance, well yield, and system integrity.

Lifespan and replacement considerations

Knowing the expected life of components helps you plan financially.

• Submersible pump: 8–15+ years depending on water quality and usage.
• Jet pump: 5–15 years depending on maintenance and usage.
• Pressure tank: 5–15 years depending on type (bladder tanks often fail less suddenly).
• Pressure switch: 5–10 years depending on use and environment.

If your pump is older than 10 years and experiencing problems, planning for replacement can avoid emergency service. Replacing at-risk components proactively can be cheaper than emergency replacement and water damage remediation.

Cost considerations and budgeting

Costs vary widely by region, well depth, and system complexity. Typical ballpark figures:

• Bacterial water test: $25–$100.
• Comprehensive water test (chemical contaminants): $100–$300+.
• Pressure switch replacement: $50–$200 (parts + labor).
• Pressure tank replacement: $200–$1,200 depending on size and type.
• Pump replacement (submersible): $800–$5,000+ depending on depth and horsepower.
• Professional service call/inspection: $100–$300.
• Well disinfection (professional): $150–$400.

Budget annually for tests and small maintenance, and set aside funds for major repairs or replacement every 8–15 years.

Efficiency and upgrades to extend pump life

You can reduce wear and energy costs with a few thoughtful upgrades and habits:

• Install a properly sized pressure tank or add a secondary tank to reduce cycling.
• Use a soft start controller or variable speed drive for large pumps to reduce startup stress (consult a professional).
• Replace corroded wiring and use properly sized conductors to reduce electrical strain.
• Install prefilters to reduce sediment entry into the pump and protect water-using appliances.
• Conserve water and spread heavy water use (laundry, irrigation) to avoid continuous pump operation.

Safety tips and best practices

Safety should always be your top priority.

• Always turn off electrical power before working on any component.
• Avoid working alone if you’ll be lifting heavy equipment or performing electrical checks.
• Don’t attempt to pull a submersible pump without the right rigging or experience—these pumps are heavy and can be dangerous.
• Keep chlorine and other disinfectants stored safely and never mix chemicals.
• Be cautious around the wellhead—exposed casings and pipes can be sharp or contaminated.

Record-keeping: your maintenance log

Keep a maintenance log to track tests, repairs, and component ages. Your log should include:

• Date and results of all water tests.
• Dates of professional inspections and service actions.
• Parts replaced and pressure switch settings.
• Any notices of changes in performance (pressure drops, noises).
• Receipts and contractor contact info.

A good log helps with warranty claims, resale value, and diagnosing recurring problems.

Checklist: simple steps you can take today

• Check the well cap and surrounding area for damage or contamination.
• Run and listen to faucets; note any change in pressure or noise.
• Test for bacteria annually through a certified lab.
• Keep vegetation and chemicals away from the well site.
• Verify that the pump cycles normally and that the pressure tank does not short-cycle.
• Schedule a professional inspection if your pump is older than 10 years or if you detect persistent problems.

Final thoughts

If you keep up with regular inspections, water testing, and simple preventive tasks, your well pump will serve you reliably for many years. Most maintenance you can do yourself is visual inspections, listening for unusual sounds, monitoring pressure, and keeping the wellhead area clean and protected.
