Top 5 Reasons for Well Pump Failure — Pierce County, WA

Written by on . Posted in Blog

You rely on your well pump to get the water you need for your family. So, when it’s not working as you would like, it’s a serious inconvenience to you and your loved ones.

But, what’s the problem with your well pump? Let’s look at some of the most common reasons for well pump failure and how these issues can be resolved.

1. Age. Did you know that well pumps have a lifespan of about 8 to 12 years? The lifespan can be shortened or lengthened depending on the quality of your water, the frequency of pump use, and the quality of the installation. If your well pump is nearing its expiration date, it may be time to consider a new one.

2. Electrical failure. If there is an electrical surge or short in your well pump, or if it was hit by a lightning strike (which is more common than you think), the pump motor can become damaged. You may not notice this failure at first, since sometimes it keeps working for a week or two before failing completely.

3. Corrosion. Are the chemicals in your water eating away at metal well casings? Water well contractors should select the appropriate liner to resist corrosion, but occasionally problems with corrosion still occur. Similarly, bacteria could also form a gellike slime called biofilm, which traps other chemicals and minerals and slows water flow.

4. Over-pumping. If you’re using water at a faster rate than your well can produce, then the pump can stop working completely. Over-pumping depletes the water source and increases corrosion and other problems. It could even plug the area where water flows into the well.

5. Poor well design and construction. If the well wasn’t properly constructed in the first place, there will be problems with the well pump. After all, there are a lot of things a well contractor needs to be aware of, such as:

  • Right choice between perforated well liner and well screen
  • Proper slot size of well screen
  • Best placement of well screen and liner
  • Ideal location of pump

If there is an issue with any of these aspects, the well pump may cease to provide you with the clear, cool water your family relies on.
