Learn Portuguese (Portugal): A torneira é nova.

We use é (from the verb ser) because being new is treated as an essential, defining characteristic of the object, rather than a temporary state like being dirty or turned on.

Why is the word for "new" written as nova instead of novo?

In Portuguese, adjectives must match the gender of the noun they describe. Since torneira (tap) is a feminine noun (as seen by the A before it), the adjective changes to its feminine form, nova.

Is torneira used for all types of taps?

Yes! Whether you are talking about a kitchen faucet, a bathroom basin tap, or a bathtub tap, you use the general word torneira.
