Kitchen plumbing services connect dishwashers and ice makers to properly sized supply lines with dedicated shutoffs, eliminate garbage disposal drain clogs by correcting undersized trap arms, and route sink and pot filler supply through Type L copper or Uponor AquaPEX with Viega ProPress fittings. Bonded Plumbworks’ licensed plumbers install Sioux Chief air gap devices, Watts PDI-rated grease traps, and BrassCraft quarter-turn ball valves at every appliance connection in compliance with applicable state building codes.
What Is Kitchen Plumbing
Kitchen plumbing encompasses the water supply lines, drain-waste-vent connections, and appliance hookups that deliver water to and remove wastewater from kitchen fixtures and appliances. A residential kitchen plumbing system includes hot and cold supply lines to the sink and dishwasher, a drain assembly with P-trap and garbage disposal connection, a dishwasher drain loop or air gap, and dedicated water lines for ice makers and instant hot water dispensers. The International Plumbing Code (IPC) and applicable state building codes specify minimum pipe sizes, air gap requirements, and grease waste handling standards for kitchen installations. Backflow prevention protects the potable water supply from contamination by ensuring water flows in one direction only — every kitchen plumbing connection to a dishwasher, ice maker, or irrigation line requires an appropriate backflow prevention method. An outdoor backflow preventer is required on any kitchen plumbing extension that serves exterior fixtures such as outdoor sinks or hose connections, preventing irrigation chemicals and soil bacteria from entering the home’s drinking water. CSST (corrugated stainless steel tubing) flexible gas line connects gas ranges, cooktops, and wall ovens in kitchen plumbing projects where rigid black iron routing is impractical, particularly for island-mounted cooktops where the flexible line routes through the floor to the appliance connection.
Signs You Need Kitchen Plumbing Service
- The kitchen sink drains slowly despite cleaning the P-trap and running the garbage disposal
- Water leaks from beneath the sink cabinet, staining the base or causing wood deterioration
- Your dishwasher is not draining completely or is backing up into the sink
- Low water pressure at the kitchen faucet compared to other fixtures in the home
- The garbage disposal hums but does not grind, or leaks from the bottom flange
- You are remodeling the kitchen and relocating the sink or adding an island with a prep sink
- Foul odor from the kitchen drain that persists after cleaning
- The ice maker water line connection shows mineral buildup or drips
- Your commercial-grade kitchen produces grease waste that requires a grease trap
Our Kitchen Plumbing Process
Step 1 — Kitchen Plumbing Assessment
Our licensed plumber evaluates your existing kitchen plumbing layout including supply line material and condition, drain pipe sizing and routing, venting configuration, and appliance connections. For remodels, we review the architect’s or designer’s plans to determine what plumbing modifications are required, particularly for sink relocations and island installations that need modified vent solutions. Kitchen plumbing inspection gives you a live view of the problem before any work starts. You review the findings and approve the quote before any repair begins.
Step 2 — Supply Line Installation and Upgrade
We install or upgrade kitchen water supply lines using PEX-B tubing or Type L copper pipe. Each fixture receives dedicated shut-off valves for independent service access. Dishwasher supply lines include a dedicated valve and braided stainless steel connector. Ice maker lines use quarter-inch copper or PEX with a saddle valve replacement (self-piercing valves replaced with proper tee connections per code). Supply lines are pressure-tested at 80 PSI before connection to fixtures.
Step 3 — Drain and Vent Configuration
Kitchen drain installation includes properly sized Schedule 40 PVC drain piping, a code-compliant P-trap assembly, and connection to the home’s drain-waste-vent system. Island sinks require an island vent (loop vent or air admittance valve where permitted by local jurisdiction). Dishwasher drain connections include a high-loop or air gap device per applicable state building codes section 807.4 to prevent backflow contamination.
Step 4 — Appliance Connection and Integration
We connect all kitchen appliances requiring plumbing: dishwashers, garbage disposals, ice makers, instant hot water dispensers, pot fillers, and water filtration systems. Each appliance connection is tested for proper flow, secure fittings, and leak-free operation. Garbage disposal installation includes electrical verification, continuous feed or batch feed configuration, and splash guard fitting.
Step 5 — Grease Management Installation
For kitchens producing significant grease waste, we install and service grease traps (grease interceptors) to prevent fats, oils, and grease (FOG) from entering the drain system. Grease trap sizing follows the Plumbing and Drainage Institute (PDI) flow-rate method based on fixture count and drain size. We install both under-sink point-of-use grease traps and larger in-ground units for high-volume applications.
Step 6 — Final Testing and Quality Verification
Every fixture and appliance connection is tested for proper water flow, drainage speed, and leak-free operation. We run the dishwasher through a full cycle, test the garbage disposal under load, verify ice maker fill, and confirm hot water delivery at the faucet. Drainage is timed to ensure flow rates meet our quality standards.
Equipment and Materials
Bonded Plumbworks installs premium kitchen plumbing materials from trusted manufacturers. Faucets and sinks include brands such as Moen, Delta, Kohler, Kraus, and Blanco. Garbage disposals include InSinkErator Evolution and Badger series and Waste King Legend series. Supply lines use Uponor AquaPEX and Type L copper with Viega ProPress fittings. Drain systems use Charlotte Pipe Schedule 40 PVC. Dishwasher connections use Watts dishwasher supply lines and Sioux Chief air gap devices. Ice maker lines use BrassCraft quarter-inch copper and SharkBite push-fit valves. Outdoor ice maker water lines extend kitchen plumbing to built-in outdoor refrigerators and ice machines, requiring UV-resistant tubing and a dedicated shutoff valve to isolate the outdoor run from the indoor supply. Grease traps include Watts and Zurn PDI-rated units. Shut-off valves are quarter-turn BrassCraft mini ball valves with compression fittings.
Why Choose Bonded Plumbworks for Kitchen Plumbing
Bonded Plumbworks has completed kitchen plumbing installations and remodels since 2006. Our licensed plumbers coordinate with general contractors, cabinet installers, and countertop fabricators to ensure plumbing rough-in and trim-out align with the project timeline. A frost-proof outdoor faucet (also called a frost-proof faucet or sillcock) extends the shutoff mechanism 6 to 12 inches inside the wall so the water supply stops behind the insulated envelope, preventing freeze damage during cold snaps — an essential kitchen plumbing upgrade for homes with exterior hose bibs near outdoor kitchens. We are members of the Plumbing-Heating-Cooling Contractors Association (PHCC), maintain an A+ rating with the Better Business Bureau (BBB), and comply with the applicable state building codes and International Plumbing Code for every installation. Our technicians understand the unique requirements of island plumbing, commercial-grade appliance hookups, and grease waste management. We provide upfront pricing, handle all permits and inspections, and guarantee every kitchen plumbing project with a written warranty.

Frequently Asked Questions
How much does kitchen plumbing remodel cost? Kitchen plumbing remodel costs range from $1,500 to $6,000 depending on scope. Replacing fixtures at the same location costs less than relocating a sink to an island or adding new appliance connections. Bonded Plumbworks provides a written estimate after reviewing your remodel plans.
Where can I find kitchen plumbing services near me? Bonded Plumbworks provides kitchen plumbing services across all 39 cities. Whether you need a simple faucet replacement or a complete kitchen plumbing remodel, call (855) 557-9600 to schedule service.
Can I move my kitchen sink to an island? Yes. Island sink installations require modified drain venting because a traditional wall vent is not available. Bonded Plumbworks installs island loop vents or air admittance valves (where permitted) to provide proper drainage and prevent sewer gas from entering the home. Island plumbing requires a permit and inspection.
Can Bonded Plumbworks run a gas line for an outdoor grill? Gas line sizing for an outdoor grill depends on the grill’s BTU rating and the total pipe run length from the gas meter — a typical 60,000 BTU grill requires a minimum 3/4-inch gas line for runs under 30 feet. A gas line for an outdoor grill connects to the home’s gas system through a dedicated branch with its own shutoff valve, and Bonded Plumbworks handles the kitchen plumbing and gas work in a single visit.
What is a greywater recovery system? A greywater recovery system captures water from kitchen sinks, dishwashers, and laundry machines for reuse in landscape irrigation, reducing total household water consumption by 20 to 40 percent. Grey water recovery systems route through a filter and storage tank before distribution, and kitchen plumbing connections require a three-way diverter valve that allows switching between sewer discharge and the recovery system.
Do I need a grease trap in my residential kitchen? Most residential kitchens do not require a grease trap under standard use. However, if your home has a commercial-grade kitchen, you host frequent large-scale cooking events, or your municipality requires it, a grease interceptor prevents FOG buildup in your drain system. Bonded Plumbworks can assess whether a grease trap would benefit your kitchen.
Does kitchen plumbing work come with a guarantee? Kitchen plumbing installations from Bonded Plumbworks include a written warranty on all parts and labor. Every connection is pressure-tested and leak-checked before we leave. If any kitchen plumbing component we installed fails within the warranty period, we return and correct it at no additional cost.
