The majority of built-in dishwashers come in only two sizes: 24 inches wide and 18 inches wide, both sized to fit under a standard
25-inch-deep and 36-inch-high counter. (Be sure to get a built-in dishwasher, not a portable one, which uses temporary connections at a sink tap and outlet.) Look for the Energy Star label on any model you buy—the criteria for dishwashers became more stringent in January 2007.
2. 3/8-TO-½-INCH BRASS ELBOW
to make the turn from the dishwasher's inlet to the copper supply line. This is a standard part for dishwashers and may be included in a dishwasher installation kit.
3. TEFLON TAPE
4. ½-INCH SOFT COPPER TUBING
to bring water to the dishwasher. (The measurement refers to the pipe's outside diameter.) A 10-foot coil should be plenty.
5. TWO ½-INCH COMPRESSION FITTINGS
The number also refers to outside diameter. Each includes a brass ferrule (or compression sleeve) and a compression nut.
6. ELECTRICAL WIRE NUTS to connect wire ends.
Get ones that will fit two 12-gauge wires—either yellow or red.
7. CABLE CLAMP
to secure the electrical cable to the junction box on the dishwasher.
8. NO. 6 HOSE CLAMP
to attach the dishwasher's 5⁄8-inch drain hose to the sink's drain tailpiece.
9. PLUMBER'S STRAPPING
to hang the drain hose on the cabinet wall.
