A few common questions.
Does a garbage disposal come with a power cord?
It depends on the model; many ship without one, and manufacturers say not to reuse the old cord. Our team can add a cord to your estimate. A hardwired disposal or a missing outlet under the sink is electrical work for a licensed electrician.
My dishwasher drains through the disposal. What changes?
The new disposal's dishwasher inlet comes sealed with a knockout plug, which has to be removed or the dishwasher can back up. In California the dishwasher also needs an approved air gap.
Can I have a disposal with a septic system?
Usually. Manufacturers say their disposals work with properly sized, maintained septic systems, and some offer septic models that add a treatment to help break down waste.
What horsepower do I need?
Disposals run from about 1/3 to 1 horsepower. Smaller units handle everyday scraps; 3/4 and 1 horsepower models handle tougher scraps like fruit pits.
Will a disposal fit under my sink?
Measure the space first; some models stand over 12 inches tall. The drain connection also has to sit lower than the disposal's outlet so water doesn't stand inside. Send a photo of the cabinet with your request.
What should never go in a disposal?
Shells, glass, plastic, metal, grease, paint, solvents and chemical drain cleaners. Run cold water before, during and after grinding.
