Jammed and leaking garbage disposals are one of the most common turnover headaches for Chicago landlords. Here is how to maintain them, handle the usual failures, and know when to replace instead of repair.
Few small appliances generate as many tenant calls as the garbage disposal, and in Chicago rentals they take an unusual amount of abuse. A unit that serves a rotating cast of tenants in a Lincoln Park two-flat or a Lakeview mid-rise sees everything from coffee grounds to chicken bones go down the drain, often from renters who have never owned a disposal before.
Most failures are not dramatic. A disposal hums but will not turn, drains slowly, leaks under the sink, or simply stops. The good news is that the majority of these problems are preventable or repairable without a plumber. For owners managing several buildings, a little routine attention keeps a small service call from turning into a costly emergency and a frustrated tenant.
Understanding the handful of things that actually break helps you triage quickly and decide whether a maintenance tech, a handyman, or a full replacement is the right response.
The cheapest repair is the one you never have to make. When you turn over a unit in Andersonville or Rogers Park, leave tenants a short note on what the disposal can and cannot handle. Fibrous items like celery, onion skins, and corn husks wrap around the impellers; starchy foods like potato peels and rice swell and clog the trap; and grease is the single worst offender in older buildings.
Encourage tenants to run cold water before, during, and for fifteen seconds after using the disposal so debris flushes fully through the trap. Cold water also keeps fats solid so they move down the line instead of coating the pipes.
For your own maintenance rounds, grinding a tray of ice cubes with a little coarse salt scours the grinding chamber, and a few citrus peels cut odor. Doing this at every turnover, plus checking that the splash guard is intact, prevents the smells and slow drains that generate the most complaints.
When a disposal hums but will not spin, something is wedged between the impeller and the grinding ring. This is the most common call, and it is almost always fixable in five minutes. First, always cut power at the switch and the breaker before reaching near the chamber. Never put a hand down the disposal.
Most units have a hex socket on the underside. Fit the small Allen wrench that came with the disposal, or a quarter-inch hex key, into that socket and work it back and forth to free the jam. If there is no bottom socket, a broom handle turned against the impellers from above will do the same. Once it turns freely, remove the obstruction, restore power, and press the small red reset button on the bottom of the unit.
Keeping a labeled hex key taped inside the sink cabinet in each unit saves tenants and your maintenance staff repeated trips.
