It is of fundamental importance to decide the position of the units and of the appliances before planning the plumbing system of a corner kitchen, especially if you want to fit special appliances such as an American-style refrigerator.

To install this type of fridge with an automatic water and ice dispenser it is necessary to plan for a water supply/drain tap alongside the appliance. The connection pipe must be made from a foodsafe material.

The back section will allow the water and gas pipes to come out at any point in the wall behind the kitchen.

Nevertheless, it is a good idea for the piping to come out of the wall behind the sink base unit because it is the only readily accessible place without a back panel. From here and through the back section, the gas pipe can reach the hob. The back section can also contain the gas safety cock.
