InSinkErator is a brand name that is well-known for their design and manufacturing of waste disposal systems and instant hot water dispensers. John Hammes founded the company in 1927 in Racine, Wisconsin, where their headquarters remain today. Hammes is credited with designing and producing the first “in sink” waste disposal system, and the InSinkErator is a play on the word “incinerator”. Currently, InSinkErator produces and markets garbage disposal systems under the Evolution and Badger Series brand names.
To replace a rubber gasket, your first step will be to unplug the cord to the garbage disposal and then disconnect the drain. If you have a dishwasher installed in your kitchen, the dishwasher drain hose will need to be disconnected from the disposer. With the cord and appropriate drain lines removed, you can now grasp the sides of the mounting nut and twist it in a counter clockwise motion, which unlocks the garbage disposal. The waste disposer should then drop right down.
Garbage disposals aren’t exactly quiet, but the device shouldn’t make a terrible screeching noise either. If your appliance is guilty of shrill sounds, there are a few potential causes. The grates could have shifted causing the device to move incorrectly, or the motor could be worn out. In either case, this usually occurs when a garbage disposal is at the end of its life, so replacement is a good option.
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.
Run cold water while the disposal is on. Keep disposer and water running for 30 to 60 seconds AFTER the waste matter has cleared your drain. The waste still has a distance to go. Cold water keeps the motor, bearings and shredder assembly from overheating. It also lets the waste go down easier because the water is pushing it down. Don't use hot water, because it can melt fat and allow it to re-solidify as a blockage further down in the drain.
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.
