Following finishing work and the installation of kitchen furniture, the plumbing in the kitchen is connected to the water supply and sewerage system, as shown in this Kitchen plumbing plan. Use the flexible piping elements that come with this type of plumbing to connect the dishwasher in the kitchen. As previously stated, the sewer connection is made through a water seal to prevent the formation of unpleasant odors. To avoid gurgling in the sink, connect the dishwasher with a special valve, as shown in this Kitchen plumbing plan. The installation of a water filter is usually done in the kitchen under the sink.
