O cano da cozinha faz um barulho estranho sempre que eu abro a torneira.

In Portuguese, it is very common to use the definite article with nouns when talking about a specific thing that is already identifiable in context.

So O cano means the pipe, not just pipe.

Here, the speaker is talking about a particular pipe: the one associated with the kitchen. That is why o sounds natural.

• O cano = the pipe
• Um cano = a pipe

If you said Um cano da cozinha..., it would sound more like a pipe in the kitchen..., introducing it as less specific.

Yes, cano usually means pipe or tube, especially in everyday speech.

In this sentence, o cano da cozinha refers to the kitchen plumbing pipe.

Related words:

• cano = pipe
• tubo = tube, pipe, often more technical or physical in shape
• encanamento = plumbing / piping system

So cano is the most natural everyday word here.

Da is a contraction of de + a.

• de = of / from
• a = the

So:

• da cozinha = of the kitchen / from the kitchen

In natural English, we would usually say the kitchen pipe or the pipe in the kitchen, but Portuguese often uses this de + article structure:

• o cano da cozinha = the kitchen pipe
• a porta da sala = the living room door
• a janela do quarto = the bedroom window

Also notice:

• do = de + o
• da = de + a
• dos = de + os
• das = de + as

Not necessarily. In Portuguese, de can express several relationships, not just possession.

Here, da cozinha mainly shows association or location: it is the pipe belonging to / connected with / in the kitchen.

So this is very similar to English noun combinations like:

• kitchen pipe
• bathroom door
• car engine

Portuguese often uses de + article + noun where English uses a noun before another noun.

That is exactly how Portuguese commonly expresses this idea. Fazer barulho means to make noise.

So:

• faz um barulho estranho = makes a strange noise

This is a very normal expression in Portuguese. Even inanimate things can be the subject of fazer here:

• O motor faz um barulho estranho. = The engine makes a strange noise.
• A porta faz barulho. = The door makes noise.

You may also hear:

• fazer barulho = to make noise
• estar fazendo barulho = to be making noise

Both relate to sound, but they are not exactly the same.

• som = sound, more neutral
• barulho = noise, often unwanted, noticeable, or bothersome

In this sentence, barulho is better because the pipe is making a weird, problematic sound.

Compare:

• Ouvi um som ao longe. = I heard a sound in the distance.
• Os vizinhos estão fazendo barulho. = The neighbors are making noise.

So barulho estranho sounds very natural for a suspicious or annoying sound.

In Portuguese, adjectives often come after the noun.

So:

• um barulho estranho = a strange noise

This noun + adjective order is the most common and neutral pattern:

• uma casa grande = a big house
• um carro velho = an old car
• um cheiro forte = a strong smell

Sometimes adjectives can go before the noun, but that often changes the tone or meaning. In this sentence, barulho estranho is the normal order.

Sempre que means whenever or every time that.

So:

• sempre que eu abro a torneira = whenever I open the faucet

You could use quando in some contexts, but sempre que emphasizes repetition more clearly.

Compare:

• quando eu abro a torneira = when I open the faucet
• sempre que eu abro a torneira = whenever / every time I open the faucet

In this sentence, the speaker means that the noise happens repeatedly, so sempre que is a very good choice.

Portuguese uses the present tense here because the sentence describes a habitual or repeated action.

• eu abro = I open
• sempre que eu abro = whenever I open

This is the same basic idea as English:

• The pipe makes a strange noise whenever I open the faucet.

It is not about one single moment only. It is about what regularly happens.

The verb abrir is conjugated as:

• eu abro = I open
• você abre = you open
• ele/ela abre = he/she opens

Yes. Portuguese often omits subject pronouns when the verb form already makes the subject clear.

So both of these are natural:

• sempre que eu abro a torneira
• sempre que abro a torneira

Because abro clearly means I open, eu is optional here.

Including eu can add a little emphasis or clarity, but it is not required.

A torneira means the faucet/tap, referring to a specific faucet that both speaker and listener can identify from context.

In a house, if you are talking about the kitchen pipe, then the faucet is understood as the relevant one.

• a torneira = the faucet
• uma torneira = a faucet

If you said uma torneira, it would sound less specific, as if you were introducing just any faucet.

Yes, literally it does. In Portuguese, the normal expression is abrir a torneira for turning water on.

Likewise:

• abrir a torneira = turn on the tap / open the faucet
• fechar a torneira = turn off the tap / close the faucet

Even though English often says turn on/off the faucet, Portuguese naturally uses open/close.

Yes. In Brazilian Portuguese, torneira is the normal word for what American English calls a faucet and British English often calls a tap.

So:

• a torneira da cozinha = the kitchen faucet / the kitchen tap

If the learner is a native English speaker, it is useful to remember that torneira covers both depending on the variety of English you use.

Because the subject is singular: O cano da cozinha.

The main verb is fazer, and here it is conjugated for ele/o cano:

• o cano faz = the pipe makes

If the subject were plural, the verb would also be plural:

• Os canos da cozinha fazem um barulho estranho. = The kitchen pipes make a strange noise.

The sentence follows a very common Portuguese pattern:

Subject + verb + object + description + time clause

Breakdown:

• O cano da cozinha = subject
• faz = verb
• um barulho estranho = object
• sempre que eu abro a torneira = time clause

So literally:

• The kitchen pipe makes a strange noise whenever I open the faucet.

This is a very standard and natural word order in Portuguese.

Yes. A few natural alternatives are possible, depending on style:

• O cano da cozinha faz um barulho estranho toda vez que eu abro a torneira.
• O cano da cozinha faz um barulho esquisito sempre que eu abro a torneira.
• Toda vez que eu abro a torneira, o cano da cozinha faz um barulho estranho.

Notes:

• toda vez que = every time
• esquisito = weird / odd
• Changing the order can shift emphasis, but the meaning stays basically the same.

Both can mean strange or weird, but they are slightly different in tone.

• estranho = strange, unusual, odd
• esquisito = weird, odd, sometimes more strongly unusual

In this sentence, both work:

• barulho estranho = strange noise
• barulho esquisito = weird noise

Estranho is often a bit more neutral and is a very safe choice for learners.

A rough pronunciation guide in Brazilian Portuguese:

• cano ≈ KAH-noo
• cozinha ≈ ko-ZEEN-ya
• barulho ≈ ba-ROO-lyoo
• estranho ≈ es-TRAN-yoo
• sempre ≈ SEM-pree
• torneira ≈ tor-NAY-ra

A couple of useful notes:

• nh in cozinha and estranho sounds like the ny in canyon
• lh in barulho sounds like a palatal ly sound, not an English l
• Final o in Brazilian Portuguese is often pronounced more like oo than a strong English oh

These are only approximations, but they help a lot at the beginner stage.
