if enzymes clear our drains, and lactobacillus is one of them, why aren't we putting yogurt down our drains?

if enzymes clear our drains, and lactobacillus is one of them, why aren't we putting yogurt down our drains?

Gemini: "While enzymes and bacteria can help maintain drains, yogurt should not be poured down the drain because its high fat, protein, and sugar content can clog pipes, solidify in cold water, and cause sewage issues. While probiotic cleaners use similar beneficial bacteria, yogurt is too thick, and its components can actually damage or clog plumbing systems.
Why Yogurt is Bad for Drains:

Solidification: Dairy fats can clog pipes, leading to slow drainage or even floods.
Nutrient Source for Bad Bacteria: The proteins and fats in yogurt can provide food for harmful bacteria, causing unwanted odor and buildup.
Ineffective Concentration: Yogurt is far too thick to be effective and will create a mess rather than breaking down organic matter."

So I'm asking all here at DU, how many floods have you caused with yogurt poured down the drain? If yogurt damages plumbing systems, we're eating this stuff?

That continued fermentation process gives way to a watery whey, which though loaded with probiotics is not going to clog a drain. Silly, silly, silly.

I have a sand mound septic system. Also use Rid-X which has other kinds of bacteria to break down biological material.
