"I've been told I can't have a disposer with my septic system. True or false?"
False. Even conventional InSinkErator disposers have always been safe for properly sized septic systems. For example, if your system is sized for a dishwasher or clothes washer, it can handle a disposer. After all, a disposer uses only about as much water per day as one flush of a toilet. But there are additional advantages when you choose the Septic Disposer.

"How does the Septic Disposer work?"
Every time you operate Septic Disposer, it automatically injects our exclusive Bio-Charge solution from a replaceable cartridge. Millions of microorganisms go to work immediately to break down food waste before it enters your septic system. Once in your septic system, Bio-Charge continues digesting both food and household waste.

"Do I still need to use septic additives?"
No, not at all. The Bio-Charge solution is a highly-concentrated, complete septic additive. Bio-Charge is injected automatically with each use of the disposer. So you'll never again have to remember to flush additives down the toilet. Or worry about handling or spilling chemicals. Bio-Charge is also specially formulated to reduce pipe buildup and control odors. And each cartridge lasts up to 4 months.

"Does Septic Disposer use a lot of water?"
Very little. Septic Disposer's high-speed grinding action produces very fine waste particles that completely flush down the drain with less than a gallon of water. In fact, it uses about the same amount of water as one flush of a low-water-consumption toilet.

"Is the Bio-Charge Treatment an exclusive formula?"
Yes. It's manufactured to InSinkErator standards by the nation's largest producer of septic additives and waste water treatment chemicals. Its effectiveness and safety have been thoroughly tested and documented by long-term tests in residential septic systems.

"How often do I have to change the Bio-Charge cartridge?"
About once every 4 months. Instead of using a septic additive every month, you only have to change Bio-Charge cartridges approximately 3 times a year. According to a University of Wisconsin study, the average consumer uses the food waste disposer 2.3 times per day. At this rate each bottle will last 3-4 months. Changing the cartridge is easy too. Remove the empty cartridge with the push of a button, then open the new cartridge and snap it in place.

"Is Septic Disposer more complicated to install?"
It's as easy as a conventional disposer. All InSinkErator models use standard plumbing connections. To view our installation tutorial, click here.
