InSinkErator Ok For A Septic System?


Just speaking to my plumber, he is recommending against a waste disposal unit in my new place. I spoke to my other plumber and he says it's fine.

I can see the logic behind both points of view. I'm just wondering what you guys recommend.

There was one at the house we grew up in, it had an ancient clay septic tank. They aren't a problem unless you dispose of things that don't break down easily.

Re: InSinkErator Ok For A Septic System?


I do not recommend them, any job where we have installed them where they never had one gave us problems. Most people do not use them correctly.
I would not put one in my house with a septic which is what I have. It is just asking for trouble.

Re: InSinkErator Ok For A Septic System?


My parents have had one at their septic served house for 40 years. My entire neighborhood of septic served houses (15 total) are all 30 years old, have had no major septic issues and all had disposers originally installed.

So I would do it.

What type of damage could be caused by having a garbage disposal and a septic?

Instead of scraping your plate in the trash you grind it up and send it in your septic tank. By doing that you are dramatically increasing the amount of fat and oil in your septic system which doesn't break down easily. Mix in coffee grinds, rice, pasta and other starchy foods that don't break down easily and you will find having to get your tank pumped more often.

Re: InSinkErator Ok For A Septic System?


I've never seen another one like it, but wasn't really looking.
Mine says Septic Disposer on the ring. Not sure if it's just a gimmick or special. Was installed when I bought the house. Says nothing special on the unit itself.

I had another house with septic and a disposer and didn't have any problems.

Re: InSinkErator Ok For A Septic System?


In shortened system life and increased need for pumping, you could put a cost of $100-1000 a year depending on many variables such as what you put down the sink, what kind of soils you have, how over-designed the system is, etc.

I've listened to both arguments and the end result is...

We put them in all the time. Never had a problem or complaint.

Re: InSinkErator Ok For A Septic System?


Code forbid them here---
I have a septic system--and a disposer--which I only use for the tid bits that come from rinsing a plate after I scrape off the main mess into the garbage--

Nothing major ever goes down there---

Not a big fan of this. Most septic systems (in our neck of the woods) are in remote settings. Wed have fights between the bears, coyotes, foxs, mountain lions and the family dog.

They actually made a line that had a cartridge of enzymes that helped decompose the waste. But you had to refill it every few months.

I bet not. I lloked up Kane County and the Illinois State plumbing code, and Kane County Department of Health. It seems like it is advised against, but certainly not codified against.

The guy who pumps out my septic ( honey dipper ) gave me explicit instructions on how to care for my system. No disposal, no powdered laundry detergent, no cooking oil down the drain, add liquid enzymes monthly, and use as little bleach as possible.

The oils and detergent which rarely fully dissolves unless using very hot water will clump and will clog the lines in the leach field. The bleach kills the enzymes which then slows the decomposition. Add large particles of food waste and problems happen.

In my experience when a disposal is installed people think then can shove almost anything down there and never use enough water.

The problem with laundry detergent is most people use too much.

Re: InSinkErator Ok For A Septic System?


Cold water only when running the disposal, no rice or celery (plugs the drain lines).

Never had or heard of a single issue with a disposal on septic field.

Insinkerator still makes the septic asset unit (I don't feel it necessary).

Re: InSinkErator Ok For A Septic System?


When we had our septic tank pumped out I asked the man, whose family been in the business forever, what he thought about garbage disposals and he said he thought the food scraps helped the digestion taking place, something about how it helped balance things out with the laundry detergent. For this reason he advocated against a gray water system which we were thinking about doing because of the ongoing drought.

He also said be careful with bleach as it kills the micro organisms that are doing the digesting and NEVER wash out latex paint into a septic system. He said that the latex can and will clog everything up.

Install one only because it's one of those things that belong in every modern house. It's something that you can use for convenience when necessary but it doesn't mean that you have to use it every day.

When I lived in neighborhood that didn't have public water or sewage, I was very discriminate as to what went down the drain (for the sake of preventing the need to pump) however there are those times when I just needed to grind because I was having a dinner party and I didn't have time or patience to clean out the cross-hairs of a standard drain.
