How can laundry detergent harm septic system? 

Using the wrong type of laundry detergent can cause a number of issues in septic systems. Detergents that contain phosphates and other harsh chemicals can clog pipes by forming large, insoluble particles which are difficult to flush away. These particles can also accumulate in leach fields, leading to reduced efficiency of wastewater treatment.

Additionally, harsh chemicals can kill off beneficial bacteria in the septic system, leading to degraded water quality. Because of these potential issues, it is important to use laundry detergents that are specifically formulated for use with septic systems. 

How many loads of laundry can I do with a septic tank?

The amount of laundry one can do with a septic system depends on the size and capacity of the tank. On average, a household of four should be able to do up to 10 loads of laundry per week without any issues. 

However, it is important to spread out washing over several days instead of doing all the laundry in one day so that the septic system has enough time to break down the waste. If too much laundry is done in one day, it can overwhelm the tank and cause it to back-up. To ensure optimal performance of the septic system, it is best to avoid overloading it with laundry. 

In addition to using the right type of detergent and avoiding overloading the tank, individuals should also ensure that their septic system is regularly maintained. This includes having it professionally inspected every three to five years, as well as pumping out the tank when necessary. Doing so will help keep the septic system functioning properly for many years to come.

Is Tide laundry detergent safe for septic systems?

Tide detergent pods enhance the effectiveness of liquid laundry detergent with their additional layer of efficiency. Although generally safe, they can cause excessive suds in an aerated septic system, just like liquid detergent.

What features should I look for when choosing a detergent for my septic system? 

When selecting the best laundry detergent for your septic system, there are several important factors to consider. Firstly, choose a product made from natural or plant-based ingredients, as these tend to be safer and gentler on plumbing and wastewater treatment processes. 

Secondly, select a detergent that is low sudsing, this means less foam which helps reduce clogging. Finally, opt for an enzyme-free detergent to avoid overloading the septic system's bacteria with too much work. As you will see, the below list of 19 best laundry detergent for septic system in 2023 showcases a variety of options to suit your needs:
