Quick Answer
Jet pumps have a higher failure rate than submersible pumps due to their exposure to air, which causes overheating and reduces their lifespan. Additionally, the presence of debris and sand in the well water can clog the jet pump's intake, leading to premature failure. These factors contribute to a higher failure rate compared to submersible pumps.
Environmental Factors
Jet pumps are more susceptible to environmental factors such as temperature fluctuations, humidity, and exposure to dust and debris. These conditions can cause the pump’s components to deteriorate faster, leading to premature failure. In contrast, submersible pumps are submerged underwater, protecting them from these environmental stressors.
Clogging and Contamination Issues
The intake of a jet pump is typically located above the water level, making it more prone to clogging and contamination. Sand, sediment, and debris can accumulate in the intake, reducing the pump’s performance and lifespan. Submersible pumps, on the other hand, have their intake located below the water level, reducing the risk of clogging and contamination.
Comparison of Lifespan
The average lifespan of a jet pump is around 10-15 years, whereas submersible pumps can last up to 20-25 years or more, depending on the quality of the pump and the water conditions. This significant difference in lifespan is largely due to the environmental factors and clogging issues mentioned earlier. By choosing a submersible pump, water well owners can enjoy a longer-lasting and more reliable pumping solution.
