In Thornton, a disposal that hums, stays silent or drips under the sink usually has a jam, a tripped thermal switch, a worn seal or a failing motor. A plumber can sort out which and also check whether the kitchen drain is the real bottleneck. Call the number on this page to be connected with a local plumber in Thornton.

What happens when you call
The number here reaches an independent plumber who serves Thornton. You'll describe what the unit is doing: humming, silent, leaking or grinding slowly. On site, the plumber cuts power, checks for a jam and tests the reset and switch. Then they look at the seals, the drain connections and the dishwasher hose, and run water to see how fast the kitchen line drains. If the motor or housing is shot, they'll talk through replacement models that fit your sink and use.
Cost factors
- Freeing a jam or resetting the motor versus installing a new unit
- The horsepower and build of any replacement you choose
- Whether the trap, tailpiece or sink flange also needs new parts
- Hardwired units, or a switch or outlet that isn't working
- Extra work if the kitchen branch line is clogged
- Tight cabinets packed with filters, bins or a water treatment unit
Thornton conditions
Most of Thornton's homes are newer than the metro average. Census survey figures give a median build year of 1997, with roughly 22% built before 1980, mostly in the older southern neighborhoods. Many disposals installed by builders in the 1990s and 2000s have already been replaced once or are due. In the older south end, kitchen lines have had longer to collect buildup.
Thornton's water is hard, averaging about 230 mg/L per the city's water quality report, and the treatment plants don't remove hardness. That can leave mineral film on sink flanges and faucet parts, though it rarely stops a disposal by itself. If you have a softener or filter under the sink, mention it when you call so the plumber knows how much room there is to work.
The city maintains Thornton's wastewater lines, and the wastewater is treated at Metro Water Recovery. The city's permit list says replacing plumbing fixtures doesn't need a permit, while plumbing modifications do; ask the plumber which category your job falls into.
Before the plumber arrives
- Turn off the switch and unplug the unit or shut its breaker
- Clear out the cabinet under the sink
- Don't pour chemical drain cleaner into the unit
- Note the brand and model if you can see the label
- Check whether other drains in the house are slow
