Is Fabric Softener Safe For Septic Systems?

Liquid fabric softeners are added to the final rinse cycle in the washing machine. They contain a variety of petroleum-based chemicals, emulsifiers and fragrances to soften fabric and give it a pleasant scent.

Septic tanks contain bacteria and enzymes that help break down organic waste. Chemicals from household fabric softeners and detergents can damage this ecosystem, making it difficult for bacteria to decompose waste effectively. Because the solids break down more slowly, they accumulate faster, causing your tank to fill more quickly. The longer you use fabric softener, the worse the problem becomes. This buildup can cause backflow issues and sewage backup inside your home. It can even lead to a total system failure, costing you expensive plumbing repairs. These same chemicals can also harm the environment by leaking into local drainfields and contaminating groundwater.

What Are the Signs That Harm Has Already Been Done?

Fabric softener can cause widespread damage to your plumbing system. The following signs may indicate a problem.

• Slow-moving drains. If the water in your shower or sink drains more slowly than normal, it could be a sign of sludge buildup or clogs due to fabric softener use.

• Gurgling noises. Clogs and damaged septic components can cause trapped air inside your plumbing pipes. This trapped air can cause gurgling noises when your washing machine drains or you flush your toilet.

• Foul odors. If the area around your septic tank has a foul odor or you notice an unpleasant smell coming from drains in your home, it could be a sign that waste isn’t filtering correctly.

• Wet spots in your yard. If your septic tank fills up, it can start to overflow into your yard. Flooding can be a sign that solid waste isn’t breaking down as quickly as it should.

• Frequent pumping. Depending on the size of your family and your septic tank, you should be pumping your tank every three to five years. If you’re pumping more often than that, it could be a red flag that your tank isn’t breaking down organic material fast enough.

Are There Septic-Safe Alternatives?

Fortunately, there are several septic-safe alternatives to fabric softeners, so you can still keep your clothes feeling soft and smelling fresh.

• Vinegar. Add a half cup of white vinegar to the final rinse cycle in your washing machine to remove odors and keep your clothes smelling fresh and clean.

• Wool dryer balls. Throw in a couple of wool dryer balls into your dryer to help absorb moisture, reduce drying time, cut down on static and eliminate wrinkles.

• Essential oils. If you love the scent that fabric softener adds, consider using essential oils. Apply a few drops to wool dryer balls for a chemical-free fragrance.

• Septic-safe fabric softeners. Read the labels and look for brands that mention septic-safe ingredients. Some brands are formulated without harmful chemicals that can hurt your septic system.
