The average cost to replace a well pump is $1,600
If you get that nasty eggy smell when you turn on the faucet, along with low or uneven water pressure, you probably need a new well pump. Costs vary considerably for well pump replacement but typically fall between $100 and $4,000. Variables include pump size, well depth, and replacement method. If your well is your primary water source, it's important that you replace a faulty pump ASAP.
How Much Does Well Pump Replacement Cost by Type of Pump?
Well pump prices range from $100 to $4,000 without the additional cost of installation, new pipework, or wiring.
Jet Well Pump
Shallow jet pumps, designed for wells 25 feet deep or less, cost between $100 and $500, with an average cost of $300. These low-end units are budget-friendly if your well is shallow, but their components aren't as durable as many other well pump types, and they don't tend to last as long.
Deep well jet pumps, for wells of up to 150 feet deep, are pricier but are more powerful. They also last much longer, being made from higher quality materials like cast iron, stainless steel, and carbon ceramic. Deep well jet pumps cost between $675 and $745.
Jet pumps are most commonly replaced with submersible pumps today because submersibles are always self-priming, unlike jet pumps that often stop working due to loss of prime. A self-priming pump is always full of liquid with no air ingress in the pump cavity or suction line, so it's primed and ready to start working at any time.
A pump that requires priming is less efficient as, even with automatic priming, it uses power to prime itself, drawing in liquid to replace the air in the cavity and suction line. Plus, submersibles can deliver greater water volume and pressure without excessive strain.
Submersible Well Pump
Submersible pumps cost between $250 and $1,200. At the lower end, shallower wells that require lower horsepower to deliver adequate water pressure can get away with pumps between $200 and $500. If your well is deeper and requires more power to move enough water for your household, expect to pay between $700 and $1,200.
Remember, too, that with submersible pumps, particularly if you're replacing an old jet pump, you'll need to budget for new pipework, which could cost anywhere between $250 and $2,500 depending on how much pipe you need.
Solar Well Pump
Solar well pumps are costly, with basic models starting around $2,000. Higher-end solar pumps for deep wells can cost up to $4,000. However, these pumps harness the sun's energy, so you don't need to rely on the local electricity supply to power your well. This is a good choice for those concerned with reducing their carbon footprint, saving on energy costs, and reducing reliance on mainstream utilities.
Hand Well Pump
Hand well pumps require physical labor to pump the water, but they are inexpensive, starting at around $150. These are useful in areas with frequent power outages, as they'll continue to work (as long as you put in the work) regardless of whether you've got power. On the plus side: you’ll have A+ biceps.

What Factors Influence the Cost of Well Pump Replacement?
It's not as straightforward as just picking the pump that falls within your budget. When it comes to well pump replacement, several factors determine cost.
Shallow and narrow wells require smaller pumps and less effort to install and therefore cost less. The deeper and wider the well, the more you'll pay for the pump and the labor necessary to complete the job.
Your type of pump is the biggest variable regarding the cost of replacement. Shallow pumps and hand pumps can cost as little as $100, while high-pressure, high-capacity solar pumps can set you back $4,000.
If you're replacing a jet pump with a shiny new submersible pump, you'll likely need to add or replace pipework, too. You may also need some pipework repaired or replaced with a standard well pump replacement. How much pipe you need impacts how much you'll pay for materials and how much you'll pay for labor.
Just like pipework, if you need new wiring or electrical repairs, this increases your total cost. A local electrician can give you an accurate quote based on the amount of work and the complexity of the job.
Pressure Tank Replacement
Replacing your well pump may not be enough. Sometimes, the problem stems from an issue with your pressure tank, in which case you'll want to replace both at the same time. Replacing the tank generally costs between $800 and $3,800.
“If your well system uses a combination pump or pressure tank it is usually not cost-effective to replace one component or the other. It's usually easier and less expensive to replace the whole system,” says Botelho. "A simple way to determine if the tank is bad is to operate any fixture, and if the pump kicks on any time the water runs, that's usually a sign of a defective tank. If the tank can't hold pressure, the pump will have to run to supply water to the fixtures.”
How Much Does It Cost to Install a Well Pump Yourself?
Replacing a well pump is a big, challenging job that's probably best left to the professionals. At the very least, before you even think about replacing the well pump yourself, you should hire a local plumber to confirm that it actually is your well pump that's the problem and not something else that might be easier to fix.
You'll still need to pay for the pump (between $100 and $4,000) and any pipes that need replacing, starting at around $200. Labor typically costs between $300 and $500, depending on the scope of the job.
However, hiring a pro is definitely the safer option. If you get it wrong, you could do more damage and end up having to buy a second new pump and still hire a contractor to finish the job for you.
"While a well pump replacement may seem like a relatively simple job, keep in mind that it’s the main water supply for your home, and something as minor as not properly priming the pump or water line can instantly render your pump useless,” says Jeff Botelho, Expert Review Board member, and plumber. “Paying for the job once can be costly enough. Paying for it twice could be financially prohibitive for many homeowners. Consider the risks before deciding to perform major repairs on your own."
FAQs About Well Pump Replacement
How long does a well pump last?
With regular servicing, a well pump usually lasts between eight and 15 years. Variables include level of usage, frequency of servicing, and pump quality. You may also be able to hire a local well pump repair service to fix your pump rather than replace it.
However, often the cost to fix significant problems is as much as or greater than replacing the damaged pump with a new one.
How do I know if my well pump is bad?
Signs you might need a new well pump include:
Changing water pressure
Odd noises coming from the water tank
Abnormally high electric costs
Scalding shower water
How often should a well pump be serviced?
Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection should be conducted yearly. If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.
