Vinegar and Septic Treatment


What is Vinegar?

Vinegar may get defined as an acetic acid aqueous solution. It also comprises trace compounds that mainly include flavoring. Vinegar contains approximately 4 to 8 percent of acetic acid. [1]

Why is Vinegar used for cleaning?

The acetic acid in vinegar solution makes it an ideal cleaning agent in the kitchen and bathroom. In addition, the acetic acid works within the wastewater system to untangle and dissolve soap scum and hard water brines. These vinegar properties make it ideal for septic tank wastewater use.

Vinegar gets much attention in our kitchens. We often use it in food dressing and when making sauces and marinades. However, Vinegar comes in many types, and the ones you see in your kitchen may not be the ones used in septic tanks. Types of Vinegar include:

So, what are the different types of Vinegar?

So, is Vinegar safe for septic systems?


To answer this question most simply and perfectly, let’s look at the benefits of using white Vinegar in your drains and septic system.

Vinegar will dissolve the sticky buildups.

Do you know those sticky buildups in your kitchen and bathroom drainage system will ultimately cause your pipe clogging? When oils and other waste bi-products react in the drainage system, they may result in these sticky buildups.

In the long run, your pipes block. When you use White Vinegar in your sinks and toilet, it will help dissolve these sticky substances clearing your drainage system.

Vinegar dissolves soap scum.

When we shower, a mixture of hair and soap scum might be the most dangerous thing when they go down the drain. These combine and form a blockage that may affect the whole sewer system. Vinegar will help entangle and dissolve this mess to let your drain wastewater flow freely.

Vinegar dissolves most drainage dirt.

Some dirt in the sewer system may dissolve well in a white vinegar solution. So, instead of waiting for it to clog your drainage pipe, you may use Vinegar and keep them clog-free. PVC, CPVC, and PEX pipes may not freeze, but scum, oil residues, and dirt may form the most difficult clogs resulting in destructive sewer blockages.

Vinegar prevents mold formation.

Mold leads to causing most of the blockages in our drainage system. Mold tends to grow on the moist areas of our kitchen and bathrooms floor. When washed in the drainage system, they easily combine with other waste material and end up causing major sewer line blockages. Vinegar helps prevent mold growth and helps dissolve waste resulting in a smooth sewer line flow.

Vinegar helps kill the harmful bacteria in the septic tank.

Have you heard of good and bad bacteria? Good bacteria don’t pose any threat to your drainage and septic system. This reaction is because most chemicals we use in our toilets and bathrooms kill germs, and these good bacteria that, when they get to our fields, cause no tremendous damage to the soil.

Therefore, Vinegar deals with harmful bacteria and by the time it gets to the septic tank, waste fields have no adverse effect.

How do you use Vinegar for adequate drainage and treatment of septic tanks?



Now that we have confirmed that Vinegar will be safe on septic tanks, you might wonder how to use it. First, you will pour a cup of White Vinegar down the drains through the sinks and shower drainage areas for effective results.

Let it stay undisturbed for at least 30 minutes, and then flush with clean water. Repeat this procedure once weekly and you will be good to go. The Vinegar will clear weekly buildup scum, oil deposits, and dirt down the drainage system to the septic tank area. This way, the wastewater will get there for more treatment and separation of waste.
