A Highland disposal that hums, leaks or will not clear the sink usually needs a jam freed, a connection resealed or a replacement. In older homes the kitchen drain behind it may need clearing too. Call the number on this page to be connected with a local plumber in Highland.

Highland homes and drains
Highland sits at the southern base of the San Bernardino Mountains, and its housing spans several eras. About 44 percent of homes were built before 1980, and the median home dates to about 1983, with the 1980s and 1990s the biggest building decades. In the older share, kitchen branch lines can be metal pipe with years of buildup, which narrows the path for ground food. In newer homes the usual suspects are the unit itself, the trap or the dishwasher hose.
East Valley Water District (EVWD) is the water agency named in city plan-check materials, and the city requires new structures to connect to sewer where available, subject to EVWD review. Whether every address is on EVWD was not verified, so check your bill. Disposals belong on homes connected to public sewer, which describes most Highland kitchens.
The City of Highland Building & Safety Division requires permits for plumbing systems. The permit counter is at 27215 Base Line Street, (909) 864-8732 ext. 232; ask the plumber whether your disposal job needs one.
Repair or replacement
| What is happening | Repair | Replacement |
|---|---|---|
| Motor hums, plate stuck | Free with a hex key | Jams again on ordinary scraps |
| No power | Reset, switch or breaker | Motor dead after reset |
| Water at the sink flange | Reseal with fresh putty | Flange or ring cracked |
| Water from the housing | Not practical | Yes; seals have failed |
| Sink drains slowly | Clear trap or branch | Only if the unit also fails |
Signs to watch
- A reset button that trips after a few seconds of grinding
- Rust stains or wet spots on the bottom of the unit
- Water rising in the other basin of a double sink
- Gurgling from a nearby drain when the kitchen sink empties
- A rattle that continues after you remove visible debris
Seasonal notes
Highland's foothill location means colder nights than the valley floor in winter, but a disposal under a kitchen sink sits inside the heated house and is not a freeze concern. The busier risk is holiday cooking, when grease, peels and bones go down together. Scrape plates into the trash, run cold water while grinding, and save the disposal for small scraps. A leak under the sink should be shut off right away to protect the cabinet.
