Can My Septic Tank Handle a Dishwasher?

When there are dirty dishes to tackle after dinner, and all you want to do is relax on the couch with your favorite show, a dishwasher can really come in handy.

The good news is that you can have a dishwasher with a septic tank, but it's not quite as easy as just hitting a button, turning off the kitchen light and heading to the TV.

Septic tanks contain a delicate balance of bacteria that are necessary for treating wastewater and eliminating potentially harmful pathogens. Overuse of your home's hot water appliances, harsh chemicals and even antibacterial soap can sometimes lead to plumbing issues and disrupt the tank's balance. By following some simple dos and don'ts when using a dishwasher with a septic tank, you can enjoy the convenience of clean, stress-free dishes.

Can You Use a Dishwasher With a Septic Tank?

Installing a dishwasher if you have a septic tank is considered perfectly safe. However, some factors to consider include the age of both your dishwasher and septic tank, your water usage and the type of soap you put in the dishwasher.

Older septic tanks paired with newer dishwashers can lead to an imbalance of water use, as older systems may not have the power to handle the water demands of newer appliances. Before installing your dishwasher, it's a good idea to schedule a septic tank inspection and/or maintenance to ensure your tank is up to the task.

Monitoring your water usage is essential when you have a septic tank, as running too many hot water appliances at once can cause a strain on your system. You'll also want to make sure to use dishwasher soap that's specifically designed to work with septic systems. Many commercial detergents contain harsh ingredients that can have a negative impact on your septic tank, leading to clogged pipes and inefficient operation.

What Should You Be Aware of If You Have a Dishwasher and a Septic Tank?

When using your dishwasher and septic tank, one of the most important things to do is stagger your home's water use. For example, if you plan to run the dishwasher, don't run it while you take a shower or use your clothes washer. This can lead to an overconcentration of water all at once, which can cause excess strain on your septic tank and septic system.

While dishwashers are designed to thoroughly clean pots, pans and other kitchenware, be careful when loading dishes that are coated with cooking grease or cooking oil. When grease and oil drain through your dishwasher and into your septic system, these substances can increase the risk of clogged pipes. For best practices, thoroughly scrape your dishes into the trash and rinse them well before loading them into your dishwasher.

Are Dishwasher Pods Safe for Septic Systems?

Dishwasher pods are considered safe for septic systems, as long as they're free of phosphates and made with organic, nontoxic ingredients. Phosphates are designed to break down grease and grime, but they're considered harmful chemicals that can throw your septic tank off balance.

Look for Septic-Safe Detergent Pods

Detergent pods labeled "biodegradable," "septic-safe" or "environmentally friendly" are specifically designed to break down easily, and they don't release potentially harmful by-products. When shopping for pods, always look for septic-safe products, and avoid purchasing any soap that lists "antibacterial" as a benefit. These detergents can actually harm the necessary bacteria in your septic tank.
