We have an old house and are installing a dishwasher so we need to get electricity put in by an electrician but also we will need to buy all the connections for the hot water that will need to go under the sink and extensions for the waste and also the inlet and we just wondering if there is a list of parts that are standard that we could get recommended as to what to buy from Bunnings to split the hot water to the tap and the dishwasher.
We need an extension setup (refer to photo) as the sink is a bit too far away from the dishwasher. Approximately 2m.
They do sell extension kits but we are wondering, can we purchase the extension kit shown in the photos as individual items from Bunnings? 
Also, can we purchase the extension kit shown in the photos as individual items from Bunnings?
