Kitchen plumbing repairs & installations
Under-sink leak
Could be the P-trap, a supply line fitting, the drain flange, or a weeping shutoff. See leak detection and repair.
Slow or clogged drain
Grease, food particles, or soap residue in the trap or branch line. See drain cleaning.
New sink/faucet connection
Supply lines and drain assembly need to match the rough-in exactly.
Under-sink leaks & cabinet protection
Sink drain
Loose slip nuts, a cracked gasket, or a shifted assembly can drip at the connection points.
Basket strainer
The putty or gasket seal can dry out or shift, letting water seep down into the cabinet.
P-trap
A loose nut or misaligned trap arm leads to drips at the joint. See leak detection and repair.
Slow kitchen drains & grease buildup
Kitchen drains carry more grease, oil, and food residue than any other drain in the house. Over time that coats the inside of the pipe and narrows the space water has to flow through — showing up as a slow drain long before a full clog. A single slow drain is often a local blockage; multiple fixtures backing up together points farther down the line. Professional cleaning clears the blockage without caustic chemicals that can shorten the life of older pipes — see drain cleaning.
Dishwasher & refrigerator water lines
A dishwasher’s drain commonly routes through an air gap or a high loop to prevent dirty water from siphoning back in. A refrigerator line needs a fitting rated for the tubing and pressure involved. Moderately hard Jamestown water can contribute to mineral buildup at these fittings over time.
Sink, faucet & disposal connections
Kitchen sinks typically tie together faucet supply lines, the sink drain, and often a garbage disposal — each connection point is a potential leak source if not fitted and sealed correctly. A disposal not installed with correct alignment, or with loosened mounting hardware, can leak or vibrate loose during normal use. See garbage disposal repair and installation or faucet and fixture repair for connection-specific service.
Moving a sink or adding an island plumbing?
That’s a different scope than repairing an existing connection — best planned alongside cabinet or countertop work. See remodel plumbing.
Testing new connections & shutoff valves
Confirm symptoms & system
Matching a drip, slow drain, or new fixture to the part of the system most likely involved.
Inspect & test on site
Running water at the fixture, checking connections under load, and testing shutoff valves.
Explain findings & scope
What the repair involves and any limits — rental and restaurant visits coordinate around the schedule.
Kitchen plumbing FAQs
Why does my kitchen sink smell?
Usually food residue or grease in the drain, strainer, or trap — sometimes a dry trap letting sewer gas through.
Can a plumber install a customer-supplied sink?
Yes, as long as dimensions and connection points match the existing rough-in.
Why is water leaking into the cabinet?
Most often the sink drain, P-trap, a supply fitting, or a shutoff valve. See leak detection and repair.
Does a dishwasher need an air gap?
Many installations use one or a high loop to prevent backflow — confirmed during installation or service.
Can a refrigerator line be connected to any pipe?
No — it needs a properly sized and rated fitting, not just any available pipe.
When does kitchen work become a remodel?
Once it involves moving fixtures or adding new supply/drain runs. See remodel plumbing.
Kitchen plumbing acting up?
Same-day service is often available.
