As with electrical systems, plumbing systems also refer to a broad set of elements: meter, supply pipe, pipes, and drainage network.

Whether it's a renovation or the installation of a new appliance, the intervention must always be carried out by an expert. In short, the system works like this: the cold water entering the dwelling from one side feeds the various dispensers and fixtures, while on the other side it is heated by a boiler so that it can also be distributed hot.

Two pipes must reach each fixture: one for hot water and one for cold water.
