Want to cut down on your food waste charges, we can install a waste disposal unit called an Insinkerator. Fitted easily and discreetly under the sink, an Insinkerator effortlessly grinds food waste into tiny particles that are automatically flushed down a standard kitchen drain into the local waste treatment system or a septic tank. Simply scrape your waste food into the sink and flush it down the plug hole with some running water and push the air switch to start the grinding.
