The kitchen is the hardest-working plumbing zone in most homes — faucet, sink, garbage disposal, dishwasher, ice maker, and sometimes a pot filler all sharing the same supply and drain lines. When something goes wrong, or when you're renovating, getting the plumbing right makes the difference between a kitchen that functions flawlessly and one that causes problems for years. Here's what Las Vegas homeowners need to know about kitchen plumbing.
Most Common Kitchen Plumbing Jobs
- Kitchen faucet replacement — Upgrading a faucet is one of the easiest ways to refresh a kitchen's look. We install any brand, pull-out, pull-down, touchless, or commercial-style.
- Garbage disposal installation or replacement — A failed disposal usually needs replacement rather than repair, and it's a quick one- to two-hour job.
- Dishwasher hookup — Proper hot water supply and drain connections ensure your dishwasher works efficiently and doesn't leak.
- Kitchen sink drain repair — P-trap leaks, corroded drain baskets, and slow kitchen drains are the most common kitchen plumbing calls.
- Refrigerator ice maker line — Running a water supply line to a new refrigerator for the ice maker and water dispenser.
- Pot filler installation — A wall-mounted faucet over the stove that fills pots in place. Requires running a supply line inside the wall to the correct location.
- Under-sink filter systems — Reverse osmosis and point-of-use filtration for drinking water.
Las Vegas grease warning: Grease is the #1 cause of kitchen drain clogs here. It pours out liquid but solidifies quickly in pipes — especially combined with the mineral scale from our hard water. Never pour cooking grease down the drain. Keep a container, let it solidify, and discard in the trash.
Kitchen Plumbing in a Remodel
Moving a sink, adding a kitchen island with plumbing, or installing new drain and supply lines during a renovation requires a licensed plumber. We work directly with general contractors, cabinet installers, and tile crews to hit the schedule precisely — plumbing phases that land late push every other trade back.
Key plumbing decisions to get right during a kitchen remodel: correct drain slope (1/4 inch per foot, minimum), proper air gap or high-loop for the dishwasher, supply line sizing for additional fixtures, and permit compliance for any moved or added lines.

Frequently Asked Questions
What plumbing is needed for a kitchen remodel in Las Vegas?
A kitchen remodel typically needs licensed plumbing work for moving or adding supply lines, rerouting drain lines, adding fixtures like pot fillers or island sinks, dishwasher connections, and permit compliance. Clark County requires permits for relocated or added plumbing.
How do I stop my kitchen drain from clogging?
Never pour grease or oil down the drain — the primary cause of kitchen clogs in Las Vegas (where it combines with hard water mineral scale). Run hot water while using the disposal, avoid fibrous foods, and consider annual hydro jetting if clogs recur.
Can I install a kitchen faucet myself?
A standard faucet swap on existing supply lines is doable for a handy homeowner. If supply lines are corroded, the shutoff valves are old, or you're adding a new faucet to a remodel, professional installation is the safer call.
What causes a dishwasher to back up into the kitchen sink?
A clog in the drain line shared between the dishwasher and sink is the usual cause. It can also be caused by an incorrectly installed drain loop or missing air gap, which are installation errors. A plumber can diagnose and fix it quickly.
