Přestože je potrubí poškozené, v pokoji už není voda.

Přestože means although, even though, or despite the fact that.

It introduces a subordinate clause: Přestože je potrubí poškozené... = Although the pipework is damaged...

It is a normal and correct word, but it sounds a bit more formal or written than i když, which is very common in speech.

So both are possible:

• Přestože je potrubí poškozené, ...
• I když je potrubí poškozené, ...

They are very close in meaning here.

Because Přestože je potrubí poškozené is a subordinate clause, and Czech normally separates subordinate and main clauses with a comma.

So the structure is:

• subordinate clause: Přestože je potrubí poškozené
• main clause: v pokoji už není voda

This is standard Czech punctuation.

Potrubí usually means pipework, piping, or a pipeline / system of pipes. In some contexts, English may translate it simply as pipe, but the Czech word often sounds more technical or collective than a single everyday pipe.

If you specifically mean one physical pipe, Czech might also use words like trubka or roura, depending on context.

So in this sentence, potrubí probably means the damaged piping or pipe system.

Because here potrubí is being treated as singular.

A tricky thing for learners is that potrubí has the same form in both singular and plural in some cases, so the verb helps you identify the number.

Here:

• je = is → singular
• so potrubí is singular here

In other words, the sentence means the pipework is damaged, not the pipes are damaged.

Because poškozené agrees with potrubí, which is neuter singular.

Agreement in Czech matters for adjectives and adjective-like forms:

• masculine singular: poškozený
• feminine singular: poškozená
• neuter singular: poškozené

Since potrubí is neuter, you get: potrubí je poškozené

Yes. Potrubí je poškozeno is also correct.

The difference is mostly stylistic:

• je poškozené sounds more adjective-like and very natural in everyday language
• je poškozeno sounds a bit more formal, technical, or official

Both mean essentially the same thing here:

• potrubí je poškozené
• potrubí je poškozeno

Because the preposition v means in, and for location it takes the locative case.

The noun is:

• dictionary form: pokoj = room
• locative singular: pokoji

So:

• v pokoji = in the room

This is a very common pattern:

• v domě = in the house
• v autě = in the car
• v pokoji = in the room

Here už means anymore / any longer / no longer.

That may seem strange at first, because už often means already in positive sentences:

• Už je doma. = He is already at home.

But with negation, it often shifts to the idea of no longer:

• Už tam není. = He is no longer there.
• V pokoji už není voda. = There is no water in the room anymore.

So in this sentence, už signals a change from an earlier situation.

In modern neutral Czech, voda is normally in the nominative here because it is the subject of the sentence:

• voda není = the water is not / there is no water

So: V pokoji už není voda is the normal, neutral wording.

You may sometimes see or hear genitive after negation in Czech, for example není vody, but that sounds more literary, marked, or partitive, as if emphasizing there isn’t any water. For everyday Czech, není voda is the safer and more standard choice in this sentence.

That is mainly a matter of word order and emphasis.

Czech word order is flexible, and speakers often put the most important or newest information later in the sentence. Here the sentence builds toward the key point: there is no water.

So: V pokoji už není voda sounds very natural.

A different order is also possible: Voda už v pokoji není.

That version is also correct, but the emphasis shifts slightly. It may sound more like you are contrasting water with something else, or focusing specifically on the water.

Because Czech has no articles.

So Czech does not have direct equivalents of a, an, and the in ordinary grammar. The listener figures that out from context.

That means:

• v pokoji can mean in the room or in a room
• voda can mean water or the water, depending on context

English must choose an article, but Czech usually does not.

Yes. You could also say:

V pokoji už není voda, přestože je potrubí poškozené.

This is still correct. The meaning stays basically the same, but the focus changes a little:

• starting with Přestože... puts the contrast first
• starting with V pokoji už není voda... puts the main result first

Both are natural Czech.
