Yes, you can replace a well pump yourself, provided your well is relatively shallow (under 200–300 feet). DIY replacement is highly achievable for an experienced handy person and can save hundreds in labor fees, but it requires heavy lifting, strict adherence to electrical safety, and a helper to manage the pipe and wire.
To tell if your well pump is bad, listen for unusual noises, monitor for fluctuating water pressure, or watch for sputtering faucets. A bad pump can also cause dirty water, continuously running cycles, or a sudden, unexplained spike in your electricity bill.
RPS engineers always say that you can easily install a pump by hand, DIY in any well up to 300 feet deep. Any deeper than 300 feet, the bundle of wire/pipe/plumbing with the pump becomes too heavy to lower down yourself without some help.
Knowing how many years should a well pump last is important because it can be a signal that it's time for a new piece of equipment. With proper well maintenance, your new well pump can last, on average, 8 to 15 years, though many homeowners report their pumps lasting far longer, often between 20 and 30 years!
Installing a water pump: Mistakes
A water pump replacement costs between $400 and $800 depending on the vehicle and the difficulty involved. Parts can run from $200 to $400, with labor services similarly priced. These estimates do not include taxes or shop materials, and disposal fees.
Below are 3 top causes of water pump failure caused by external issues and techniques for prevention.
Most well pump replacement projects fall between $975 and $2,575, but many factors can add additional costs. A small hand pump can cost as little as $200, while a high-end constant-pressure well pump could set you back as much as $5,000.
The earliest signs of water pump failure are usually a high-pitched whining or growling noise from the front of the engine, puddles of coolant (bright green, pink, or orange) under your vehicle, or an unexplained, fluctuating engine temperature.
A 2 gallon per minute (GPM) well is considered low-yield but can adequately serve a typical household with careful water management, such as spacing out showers and laundry, or by installing a storage tank system. While 5–10 GPM is ideal for modern homes, 2 GPM can still supply over 2,800 gallons a day.
The only difference between 2-wire and 3-wire submersible well pumps is where the motor's starting components (like capacitors and relays) are located. In a 2-wire pump, these components are sealed inside the pump motor in the well. In a 3-wire pump, they are housed in an above-ground control box.
Replacing a well pump, whether it's a submersible type or a jet pump, varies in time due to accessibility and installation complexities. Submersible pump replacement typically takes 4 to 6 hours, considering the challenge of accessing the pump and connecting plumbing and electrical systems.
The "best" pump brand depends entirely on its purpose. There is no single universal brand; rather, industry leaders specialize in distinct categories based on user needs.
To test a well pump without pulling it, first check the electrical supply and pressure switch with a multimeter to ensure power is reaching the system. Next, measure the amp draw at the wellhead, inspect the pressure tank, and perform an ohm test to check the motor windings for shorts or breaks.
With a bad water pump, coolant cannot circulate, and the engine would quickly overheat, resulting in potential breakdowns and costly repairs.
Neither switch is universally "better"; the best choice depends on your home’s plumbing age, the height of your building, and your pump's capacity. A 40/60 switch provides stronger water pressure and is ideal for multi-story homes, while a 30/50 switch is gentler on older plumbing and single-story houses.
Water pump corrosion
And in some cases, visible corrosion or buildup on the water pump itself can indicate it's failing with no other symptoms at all.
Diagnosing a failing water pump often involves:
A bad well pump is unable to filter out silt or other sediments before pumping the water up to the surface. This causes your water to appear cloudy or muddy and leads to very poor-tasting water. After a while, friction from sand, silt, and other dirt wears your well pump out at a very high rate.
The average cost for a Water Pump Replacement is between $857 and $1,106. Labor costs are estimated between $358 and $525 while parts are priced between $499 and $581. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
A submersible well pump typically lasts 8 to 15 years, though many properly maintained systems run for 20 to 30 years. Its exact lifespan depends heavily on water quality, how often the pump cycles on and off, and proper maintenance of the system's pressure tank.
Following are the major reasons for pump failure:
A bad water pump fails to circulate coolant through your engine, which almost always causes rapid and severe engine overheating. Ignoring a failing pump can lead to catastrophic, irreversible engine damage like blown head gaskets, cracked blocks, or warped cylinder heads.
