AJ Pumps & Water Treatment understands the frustration and inconvenience that arise from encountering low pressure in a jet pump. As experts in the field, we are dedicated to helping you resolve such issues effectively. In this blog post, we will explore the common causes of low pressure in a jet pump and provide insights into potential solutions to ensure optimal performance.


Inadequate Power Supply

One of the primary culprits behind low pressure in a water jet pump is an inadequate power supply. Insufficient voltage or an undersized electrical circuit can hinder the pump’s ability to operate at its full capacity, resulting in reduced pressure output.

To rectify this issue, it is crucial to ensure that your water jet pump is connected to a suitable power source with the correct voltage and amperage. Consulting one of our qualified technicians or referring to the pump’s electrical requirements can help identify and address power-related problems effectively.


Clogged or Dirty Intake Screens or Injectors

A clogged or dirty intake screen is a frequent cause of low pressure in water jet pumps. The intake screen acts as a barrier, preventing debris from entering the pump and obstructing the water flow. Over time, accumulated dirt, sediment, or foreign objects can impede the screen, reducing the pump’s efficiency and resulting in lower pressure.

To mitigate this issue, regular cleaning and maintenance of the intake screen are essential. Remove the screen and thoroughly rinse it with water, ensuring that all visible debris is eliminated. AJ Pumps & Water Treatment can help you Implement a preventive maintenance schedule to help keep the intake screen clear, and unobstructed and to promote optimal pump performance.


Air Leaks in Suction Lines 

Air leaks in the suction lines can significantly impact the water jet pump’s ability to generate sufficient pressure. When air infiltrates the system, it disrupts the priming process, leading to reduced suction and subsequent low pressure. Loose fittings, damaged seals, or cracks in the suction lines are common sources of air leaks.

To address this issue, we can provide a comprehensive inspection of the suction lines. We look for visible signs of damage or leaks and tighten loose fittings, replace damaged seals, or repair any cracks to eliminate air intake. Consulting the experts at AJ Pumps & Water Treatment can ensure a thorough assessment and professional repairs, such as pressure testing, vacuum testing, well head exposure, line locating and well flow testing.


Worn or Damaged Impeller

The impeller plays a crucial role in moving water through the pump. However, over time, it can experience wear and tear, leading to decreased efficiency and lower pressure output. Worn impeller blades or a damaged impeller can disrupt the smooth flow of water, resulting in reduced pressure.

To resolve this issue, it is advisable to consult our specialists at AJ Pumps & Water Treatment. We can accurately diagnose the problem and provide the appropriate solution, such as replacing the worn or damaged impeller. Our expertise ensures that the correct replacement part is obtained and installed correctly, restoring optimal pump performance.

Low pressure in a water jet pump can be attributed to various causes, ranging from inadequate power supply to mechanical issues. By understanding these causes and seeking professional assistance from AJ Pumps & Water Treatment, you can ensure reliable and efficient water flow in your system.
