Drain and disposal diagnosis
The drain, disposal, and dishwasher drain connection are checked together, because a backup in one is often a blockage in the shared line.
Plumbing Service · Hermitage, TN
Kitchen plumbing fails in a small space with a lot at stake: grease in the drain, a jammed disposal, a dishwasher backing up into the sink, and a leak that soaks the cabinet. We work through the sink, disposal, dishwasher connection, and supply lines as one system.
Mon–Fri: 7AM – 7PM · Sat: 8AM – 4PM · 24/7 for emergencies. Burst pipe or flooding? Shut off the main water valve first, then call.

What to look for
Kitchen plumbing fails in a small space with a lot at stake: grease in the drain, a jammed disposal, a dishwasher backing up into the sink, and a leak that soaks the cabinet. We work through the sink, disposal, dishwasher connection, and supply lines as one system.
If you have one of these symptoms, describe it when you call (615) 436-9486. The symptom, the fixture, and whether water is still running help us prioritise your visit and tell you what to shut off while you wait. If water is flooding, shut off the main valve first – see our emergency plumbing page for the steps.
How we fix it
Every visit follows the same pattern: find the fault, show you what we found, price the options, and only then do the work. No part is replaced on a guess.
The drain, disposal, and dishwasher drain connection are checked together, because a backup in one is often a blockage in the shared line.
Jams are cleared safely, the reset is checked, and a failed disposal is replaced with matching power and connections. Never put your hand in a disposal.
Supply lines, sprayer hoses, P-traps, and basket strainers are checked and sealed.
Air gap, drain hose loop, and drain connection are checked so dishwasher water goes where it should.
Hermitage homes
Grease is the number one kitchen-drain problem in Hermitage, and it does not wash away with hot water: it cools, coats the pipe, and traps food until the line closes. Scraping plates into the trash and wiping greasy pans before washing are the two habits that prevent most kitchen clogs. When a clog does form, we clear the full line and check the disposal and dishwasher connections at the same visit, so one blockage does not return as three separate calls.
Homes across Hermitage and Davidson County vary widely in age and plumbing material, so the same symptom can have different causes in different streets. That is why diagnosis comes first: a slow drain in a newer home and a slow drain in an older home with mature trees in the yard are not the same job, and they should not get the same quote. We explain the cause we found in your home, in plain language, before recommending a repair.
| What we find | What it usually means | Our recommendation |
|---|---|---|
| Disposal jammed, reset tripped, unit otherwise sound | Clear and reset | Repair |
| Disposal leaking from the housing, older unit | Housing seal has failed | Replace |
| Kitchen drain clogged with grease | Grease coats the line | Clear / jet |
| Cabinet floor soft from a long leak | Repair the leak and report floor damage honestly | Repair + report |

Questions
Turn it off, press the reset button on the bottom once, and try again. If it still only hums, turn it off and call us. Never put your hand inside, even when it is off, and do not keep running a jammed disposal.
Usually a shared drain blockage, a missing or low drain-hose loop, or a clogged air gap. We check the drain and the dishwasher connection together.
Grease, coffee grounds, fibrous foods like celery and onion skins, bones in large quantity, and anything non-food. Even approved foods should go in small amounts with plenty of cold water running.
Yes for the cabinet. Put a container under the drip, avoid using that sink if water is pooling, and call us before the cabinet base and flooring are damaged.
Call (615) 436-9486 and describe the symptom, the fixture, and whether water is still running. We give you a time window, tell you what to shut off while you wait, diagnose the fault on site, and quote an upfront price before any work begins. Emergencies are answered 24/7.
Still unsure? Call (615) 436-9486 and describe what you are seeing. We would rather answer a question than have a small leak become a large repair.
