If you’ve taken the time to invest in a well water pump, you want it to last. Many private well owners ask themselves “How long will my water pump last?” and the answer really depends on a lot of factors. Well-maintained and good quality water pumps can last up to 20 years in some cases, but their lifespan can be drastically influenced and altered by these five factors:


Like with almost any device or appliance around the home, the more you use a water pump, the quicker it will wear down. You can easily use the pump every day and have it last for years, so you don’t need to worry about limiting your usage just to try and extend the lifespan, but the amount you use the pump will usually have an impact of a lifespan. In an ideal situation, if you can minimize your usage without reducing your quality of life, then this will be beneficial for your water pump.

The Type Of Pump

The type of water pump you choose to install also has an impact on how long it will last. Some models and certain types of water pumps last longer than others. The most common kind of pump is a deep or submersible pump. Pump installation contractors install deep pumps deep in the well, not on the surface. These kinds of pumps are relatively resistant. However, they tend to be less hardy and long-lasting than shallow pumps.

The Wires

Water pumps typically make use of either a two wire or a three wire system. Essentially, the difference between these two models is quite simple: the components required to turn the pump on are inside the pump in a two wire system and outside the pump in a control box in a three wire system. The two wire systems tend to be longer lasting in general, but the three wire systems are usually easier to repair.

The Motor

The motor is the engine or power source of your water pump. It’s like the engine of a car, and the bigger and better motors are going to provide stronger and more reliable performance overall. The better quality motor you buy, the better chance you have of having a pump that will go the distance. Of course, higher quality motors are typically more expensive overall, but that added cost can actually save you money on repairs and replacements in the long run.

Sediments and Chemicals

All kinds of sediments and chemicals in the ground or environment can affect the lifespan of your pump. It’s easy for little bits of dirt and sediment to build up in the pump as time goes by, and chemicals in the area can also cause the materials of the pump to degrade slowly over time too. Naturally, the greater the exposure, the greater the likelihood of the pump eventually breaking down, and this is why it’s important to get your pump checked out by the pros on a regular basis.
