Small habits, fewer calls
Most disposal service calls trace back to a few things: something hard or stringy went in, grease built up, or a slow drip went unnoticed under the sink. Regular, low-effort checks catch these early.
Fullerton's hard water also leaves mineral film on sinks and in dishwashers. It is not a major cause of disposal failure, but cleaning the splash guard and sink flange regularly keeps residue from building up where you can see it.
The calendar
- Every use
- Run cold water before, during and after grinding. Feed scraps a little at a time.
- Weekly
- With the power off, scrub the underside of the splash guard with soap and a brush.
- Weekly
- Grind a handful of ice with cold water running to knock residue off the grinding parts.
- Monthly
- With a flashlight, check the flange, dishwasher hose and drain elbow for damp spots.
- Monthly
- Note how fast the sink drains with a full bowl; slower than usual is a drain warning.
- Every few months
- Press the reset button to confirm it is in, and make sure the hex key is still under the sink.
- Yearly
- Test the angle stops and main shutoff, and look at the dishwasher hose for cracks or kinks.
- Yearly
- Check the cabinet floor for swelling or stains that suggest a past leak.

Common questions
Does grinding ice sharpen the blades?
Disposals do not have sharp blades. Ice helps knock residue off the grinding parts and chamber.
How often should I clean the splash guard?
Weekly is a good habit, and right away if you notice a smell.
Do I need a professional tune-up?
Disposals do not usually need routine professional service. Call when a check shows a problem.
