The waste disposer is a workhorse in the kitchen and is often taken for granted. Your crusher will have no problem shredding most of the food waste, but that’s not where the problems with an obstruction are. The most common cause of blockages is the way the ground meal reacts to water or lack of water after the unit has crushed it and sends it to the siphon. When a waste disposer like this one is capped, you will often find the problem in the siphon that is on the discharge side of the disposer.
The siphon can be plugged by several things that for different reasons cause poor drainage, including:
Pour insufficient water into the crusher when grinding
Crush egg shells
Grind coffee beans
Grind potato husks
Grind banana peels
These are all huge problems that must be addressed if you want your garbage disposal to last a long time. We recommend that you service it regularly if you care about it.
