Por suerte, la fontanera consiguió desatascarlo en pocos minutos.

It means Luckily, Fortunately, or literally By luck.

It is a very common sentence opener in Spanish when something turns out well:

• Por suerte, no pasó nada. = Fortunately, nothing happened.
• Por suerte, llegamos a tiempo. = Luckily, we arrived on time.

It sets the tone for the whole sentence: the speaker is saying the result was a good one.

Because fontanera is the feminine form of fontanero.

• el fontanero = the male plumber
• la fontanera = the female plumber

In this sentence, the plumber is a woman, so both the article and the noun are feminine:

• la
  • fontanera

This is very typical in Spanish, where many job titles change form depending on gender.

Spanish usually uses the definite article with a subject noun like this when talking about a specific person:

• La fontanera consiguió... = The plumber managed...

So this is not talking about plumbers in general, but about a particular plumber in the situation.

Compare:

• La fontanera llegó tarde. = The plumber arrived late.
• Las fontaneras trabajan mucho. = Plumbers work a lot. / Female plumbers work a lot.

Consiguió is the preterite form of conseguir.

Here it means something like:

• managed to
• succeeded in

The preterite is used because this is a completed action in the past. The plumber finished the task.

A few forms of conseguir:

• consigo = I get / manage
• consigue = he/she manages
• consiguió = he/she managed

Notice that conseguir is a stem-changing verb in many forms (e → i), and in the preterite you get forms like consiguió, consiguieron.

Because conseguir + infinitive is a very common structure meaning to manage to do something or to succeed in doing something.

So:

• consiguió desatascarlo = she managed to unclog it

Other examples:

• Consiguió abrir la puerta. = She managed to open the door.
• No conseguí encontrarlo. = I didn’t manage to find it.

This structure often suggests there was some difficulty or effort involved.

Desatascar means to unclog, to unblock, or to clear a blockage.

It comes from:

• atascar = to block, jam, clog
• des- = a prefix suggesting reversal or removal

So desatascar is literally something like to un-block.

It is often used for things like:

• sinks
• pipes
• drains
• toilets

It is made of two parts:

• desatascar = to unclog
• lo = it (direct object pronoun, masculine singular)

So:

• desatascarlo = to unclog it

Spanish often attaches object pronouns to an infinitive:

• hacerlo = to do it
• verla = to see her/it
• arreglarlos = to fix them

So this is completely normal Spanish word-building.

Lo refers to whatever masculine singular thing was blocked.

Since the sentence by itself does not name the object, it must be understood from context. It could be something like:

• el fregadero = the sink
• el desagüe = the drain
• el váter = the toilet

All of those are masculine nouns, so lo would fit.

If the thing were feminine, Spanish would use la instead:

• desatascarla

En pocos minutos means in a few minutes or within a few minutes.

Here, en expresses the time needed to complete the action.

So:

• Lo hizo en pocos minutos. = She did it in a few minutes.

This is different from durante pocos minutos, which would mean for a few minutes and focuses more on duration rather than completion.

Compare:

• Lo arregló en pocos minutos. = She fixed it in a few minutes.
• Trabajó durante pocos minutos. = She worked for a few minutes.

Both are possible, but they are slightly different in feel.

• en pocos minutos = in few minutes / in just a few minutes
• en unos pocos minutos = in a few minutes

Pocos on its own can sound a bit more emphatic, often suggesting not many or only a small number.

So en pocos minutos fits very well here because it highlights how quickly the plumber solved the problem.

They are similar, but consiguió desatascarlo often sounds a bit more like she managed to unclog it after some effort.

• consiguió = managed to, succeeded in
• pudo = was able to, could

In many contexts, both could work, but consiguió often emphasizes the success more clearly.

So this sentence suggests not just ability, but successful completion.

The accent mark shows the correct stress: con-si-GUIÓ.

Without getting too technical, the accent helps indicate that the ending is pronounced correctly in the preterite form.

This is common in many third-person singular preterite forms:

• consiguió
• llegó
• salió
• comió

It is something you will see often in past-tense narration.

The structure is very natural:

• Por suerte = luckily
• la fontanera = the plumber
• consiguió = managed
• desatascarlo = to unclog it
• en pocos minutos = in a few minutes

So the pattern is basically:

Comment/opener + subject + verb + infinitive phrase + time expression

Spanish word order is often flexible, but this sentence sounds completely standard and neutral.
