Achieving Higher Water Pressure from a Submerged Well Pump

Is it possible to get better than 40/60 psi from a submerged well pump? The answer is yes, provided you consider several important factors and adjust your system accordingly. This article will explore these factors in detail and explain how to achieve higher pressures.

Factors Influencing Water Pressure

Pump Specifications

The first and foremost factor is the pump specifications. The design, size, and performance curve of the pump determine its maximum pressure capability. Some advanced models are specifically engineered to deliver higher pressures than the baseline 40/60 psi standard. Ensure that the pump you choose is rated for the desired pressure to avoid potential damage or failure.

Depth of the Well

The depth at which the well is installed affects the pressure. A deeper well requires a more powerful pump to maintain higher pressures. The relationship between pressure and well depth can be calculated using the following formula:

1 psi 2.31 feet of head

For example, a pressure of 50 psi equates to 115.5 feet of head. Many pumps can reach this pressure, but it's crucial to account for friction losses in the drop pipe.

Pipe Size and Length

The diameter and length of the pipes affect the pressure at the output due to friction losses. Using larger diameter pipes can help reduce these losses. Properly sized pipes will ensure that the pump can deliver the desired pressure.

Pressure Switch Settings

The pressure switch controls the pump's cut-in and cut-out pressures. Adjusting these settings can allow you to achieve higher pressures if the pump and system are designed for it. Ensure that the pressure switch is set to the appropriate levels to maximize efficiency and performance.

System Design

The overall design of the water system, including pressure tanks, valves, and fittings, can impact the pressure delivered at the tap. An optimally designed system will minimize pressure drops and ensure that the pump operates efficiently.

Calculating Friction Losses

Friction losses in the pipes must be considered when aiming for higher pressures. To accurately calculate these losses, you can use friction loss tables specific to the flow rate and pipe size. These tables are widely available online.

Common Mistakes and Tips for Optimizing Pressure

A common mistake is calculating lift based on the distance down to the pump, which is incorrect. The lift calculation should be based on the pumping water level in the well, which is typically above the pump. Additionally, you must account for the resistance encountered by the water as it is pushed away from the wellhead through the pipe.

To optimize your system and achieve higher pressures:

Ensure all components, including valves and fittings, are rated for the desired pressure. Use larger diameter pipes for reduced friction losses. Regularly check and adjust pressure switch settings. Consult with a professional or a pump specialist to tailor the solution to your specific needs.

By carefully considering these factors and modifications, you can achieve the desired water pressure from a submerged well pump and ensure a reliable and efficient water supply for your needs.

Conclusion: Achieving higher water pressure from a submerged well pump is possible through careful planning and consideration of specific factors. By optimizing your pump specifications, accounting for well depth and friction losses, and ensuring a well-designed system, you can enhance your water pressure and reliability.
