If you're replacing a commercial garbage disposal, then you'll either want the Drain Strainer with Crown Adapter or the Drain Strainer XL. Both of these models have a universal Crown Adapter on top that serves as a funnel to cover the hole once the commercial garbage disposal has been removed. Note that it doesn't actually attach to the sink bowl, but you'll adjust the legs to get your unit flush underneath the bottom of the sink.
STEP 4 – If you must use your hands (again, not advised) to pull out all that funky goo, see STEP 2. The disposal must be powered off and unplugged. No exceptions. Not even on a double-dog dare. Also, make sure your hand will actually fit into the opening so that you can eventually remove your hand from the opening. You may need your hand later. If you think it is going to be a tight fit, I’d suggest that you not try it all. You’ve been warned.
A continuous feed model features a switch that is generally mounted on the wall nearby. In rarer cases, an air pressure switch may be mounted on the countertop. These air pressure switches are considered safer than traditional flip switches because they guard against shock by isolating the electrical system away from the sink’s source of water. Batch feed garbage disposals do not require the installation or use of a switch. Safety codes in your community will dictate how far away from the sink the electrical switch must be located.
Speaking of resetting your garbage disposal, sometimes that’s all you need to get the appliance up and running. However, if you constantly have to press the reset button for your garbage disposal to work, then there is an underlying problem. It may be insufficient wiring or regular wear and tear, but either way, it might be best to contact your local plumbing professional for help at this point.
You should first find out whether only the disposal is broken, or if the power has gone out completely in the areas near your kitchen sink. Try resetting the circuit breaker that leads to the kitchen, or replacing a fuse if you have an older electrical box. If the garbage disposal makes no noises at all when you flip the switch, you might also want to check under the sink to see that it’s plugged in.
