I have had a garbage disposal my entire life, on a septic tank. (at my parents' house and my house)
I have never had a problem or remember my parents having a clogged drain due to it.
We used it daily. You obviously scrape your plates in the garbage first, but any remnants are easily ground up, passed to the septic and eaten.
The bacteria and enzymes easily consume food waste.
You might have to pump your septic tank like 1% sooner than someone without a disposal... Instead of every 5 years, it might be every 4 years and 11 months...
Seriously... people looove to give advice based on hearsay.
Meh.. I have a septic system and use a garbage disposal on a daily basis. Never had a problem with it. Then again, I don't shove huge quantities of food down it. Only the remnants that are left in dishes after they are scraped into the trash.
Ummmm, if you're putting into the "garbage disposal" what's left on plates AFTER scraping remaining scraps into the garbage, I'm not so sure you understand what people use garbage disposals for. Garbage disposal = giant blender under the sink that can grind up bulk beef and wash it down your drain. The idea is that with a garbage disposal, you don't have food in your trash that sits there rotting, smelling, attracting flies, etc., until the next garbage pick-up day.
Also, for others with garbage disposals, I've seen conflicting views: some people say put chicken bones down & others say don't. Supposedly the chicken bones will help "pick out" any chunks of food that might be stuck in the grates. Putting orange peel down without any running water always keeps it fresher smelling.
what would the upper class be pumping if they don't have a septic tank?
What's class have to do with septic tanks? Some (most?) of the most expensive places in my area are built where there are no municipal sewage systems.
