Kitchen Plumbing: How to Plan & Install Kitchen Plumbing & Appliances

Rough plumbing for a typical kitchen is much simpler than for a bathroom. Assuming there will be one sink and one dishwasher, only one drain line and one pair of supply pipes will be needed. All other connections -- the drain and supply for the dishwasher, a supply line for an icemaker, and even a hot water dispenser or a water filter -- are made with flexible tubing that does not run through walls.

The finish plumbing, however, can get complicated. The underside of a typical kitchen sink may look like a bewildering maze of tubes, appliances, and trap lines. This section eliminates the confusion by taking the project one step at a time.

The master plan
Remodeling a kitchen involves many operations. Usually the most efficient order of work is the following:

- Cover sensitive surfaces and remove old cabinets, flooring, and wallcoverings.

- Install the rough plumbing -- the drain, vent, and supply lines.

- Install electrical wiring and boxes and cut a hole for an exhaust fan if included.

- Apply new drywall and patch any damaged walls. Prime and paint.

- Install the flooring, then cover it with a protective drop cloth.

- Install the wall and base cabinets, as well as the countertops.

- Do the finish electrical work -- lights, receptacles, and switches.

- Install the sink, faucet, garbage disposer, dishwasher, and any other plumbing appliances.
