When designing a new kitchen, or even purchasing a home, having a center island in the kitchen is a desirable feature. Today’s islands resemble a fine piece of furniture that is accessible from all sides. Cleaning up after entertaining has become much easier with access to the dishwasher positioned in an Island bench. Particularly if the sink is also positioned in the same bench.
To install a dishwasher in a kitchen island, you must be aware of the following:
You will need: A center island with an open cabinet and an electrical outlet, Fittings to attach the dishwasher pipes to the to plumbing, Flexible copper tubing – 3/8 inch in diameter, Dishwasher drain hose and sink connector kit, 2 inch hole saw, 2 hose clamps, SAE open end wrenches, Hacksaw, Pipe wrench, Steel wool and also Teflon tape.
- The sink drain tailpiece should be removed. The tailpiece is the part that runs from where the two sinks drains combine in a double sink to the trap, and a hook-shaped pipe that holds water inside is the trap, designed to make a barrier against sewer gasses. A tail-piece that has a dishwasher drain fitting is included in the dishwasher sink kit. To fit it in where the removed tailpiece was, this tailpiece must be cut to the correct length. Once the tailpiece has been installed, tighten in place using the two slip nuts and compression washers to secure it to the piping. However, as most disposals have a dishwasher hose connection in them, skip this spec if the sink has a disposal.
- The copper tubing, that supplies the sink faucet hot water, should be located. Turn off the water supply to this pipe. You may have to shut off the main hot water supply, in some cases, there may be a valve under the sink that is easy to turn off. Cut through the copper pipe with the hacksaw ensure the ends are clean and smooth by rubbing them with the steel wool. The nuts and washers may now be installed on the tubing. On the copper tubing, the correct sized compression must be installed and then push the tubing in until it bottoms inside of the fitting. The washers need to be moved into the tee then tighten the nuts firmly.
- For the dishwasher supply, the nut and washer from the tee should be placed on the copper tubing. The tubing should then be inserted into the tee and tighten the nut.
- The dishwasher may be placed on its back on the floor. By using Teflon tape on the threads, the correct sized iron pipe to suit the compression elbow in the water inlet must be installed. Before you set them aside, the compression nut and washer must be removed from the fitting. Install the drain hose on the dishwasher drain and tighten the clamp. Guiding the tube and hose into the correct place, set the dishwasher upright and slide it into the opening.
- Using the washer and nut provided, attach the copper tubing to the fitting then tighten the nut. Through the cabinet, route the hose to the drain fitting on the sink tailpiece or disposer. Check for leaks by turning the water back on.
- The dishwasher power cord must be connected to the outlet. In order to secure the dishwasher, it is best you drive wood screws through the under cabinet mounts into the bottom of the counter top.
