Septic,Tank,Waste,SystemSeptic pumps are an essential part of any septic system. They are responsible for transferring effluent from the septic tank to the drain field or sewer line. Choosing the right septic pump is crucial to ensuring the efficient and effective operation of your septic system. With so many options available on the market, it can be overwhelming trying to find the right one. In this blog post, we will discuss some key factors to consider when selecting a septic pump.

1. Pump Capacity

The first factor to consider when choosing a septic pump is its capacity. The pump capacity refers to the amount of effluent that the pump can transfer per minute or gallon per minute (GPM). To determine the appropriate pump capacity for your septic system, you need to consider the number of people living in your household, the average daily water usage, and the peak water usage. You should choose a pump that can handle the maximum volume of wastewater your household generates.

2. Pump Power

The power of the septic pump is another crucial factor to consider. The power refers to the horsepower (HP) of the motor that drives the pump. Generally, the more powerful the pump, the higher its capacity to move effluent efficiently. However, it’s important to strike a balance between power and efficiency. Choosing a pump that is too powerful may lead to unnecessary energy consumption, while choosing a weak pump may result in poor performance. Consider consulting with a professional to determine the appropriate pump power for your specific needs.

3. Pump Type

There are different types of septic pumps available on the market, including centrifugal pumps and turbine pumps. Centrifugal pumps are the most commonly used in septic systems due to their efficiency and reliability. They are designed to move large volumes of wastewater quickly. However, turbine pumps are an alternative option for systems with limited space or a shallow pump chamber. Research and understand the pros and cons of each pump type before making a decision.

4. Pump Material

Septic pumps are typically made of either cast iron or thermoplastic materials. Cast iron pumps are known for their durability and are less likely to crack under high pressure. They are recommended for systems with heavy usage or in areas with harsh weather conditions. On the other hand, thermoplastic pumps are lighter in weight and resistant to corrosion. They are ideal for systems with moderate usage and in areas with high water tables. Consider the specific needs of your septic system and choose a pump material that will withstand its conditions.

5. Pump Float Switch

The float switch is an important component of a septic pump as it controls the pump’s activation and deactivation based on the liquid level in the pump chamber. There are two main types of float switches: tethered and vertical. Tethered float switches are suitable for pump chambers with limited space, as they allow for a lower activation level. Vertical float switches, on the other hand, are suitable for larger pump chambers and offer a wider range of activation levels. Consider the size and design of your pump chamber when choosing the appropriate float switch.

6. Maintenance and Warranty

Lastly, consider the maintenance requirements and warranty of the septic pump. Regular maintenance is essential for the longevity and efficient operation of the pump. Look for pumps that are easy to maintain, with accessible parts and clear maintenance instructions. Additionally, check the warranty provided by the manufacturer. A good warranty ensures that you are protected against any defects or malfunctions. Consider opting for pumps with a longer warranty period for added peace of mind.


Choosing the right septic pump is crucial for the proper functioning of your septic system. Consider the pump capacity, power, type, material, float switch, maintenance, and warranty when making your decision. Consulting with septic professionals can provide valuable insights and help you make an informed choice. Remember, investing in a high-quality septic pump will save you time, money, and prevent potential system failures in the future.
