Questions & Answers about Revisamos la válvula de paso.

Why is revisamos used here, and what does it mean exactly?

Revisamos is the nosotros form of revisar. In this kind of sentence, it usually means we check, we inspect, or we examine.

Depending on context, revisar can mean:

• to check
• to inspect
• to review

With something mechanical like la válvula de paso, we inspect/check the shut-off valve is the most natural idea.

Can revisamos mean both we check and we checked?

Yes. Revisamos can be either:

• present tense: we check / we are checking
• preterite: we checked

Spanish has this overlap in the nosotros form for many -ar verbs.

So this sentence could mean either:

• We check the shut-off valve
• We checked the shut-off valve

Only the context tells you which one is meant.

Why is there no subject pronoun like nosotros?

Because Spanish usually omits subject pronouns when the verb already shows who is doing the action.

• Revisamos already tells you it is we
• So nosotros is optional

You could say Nosotros revisamos la válvula de paso, but it would usually be used only for emphasis, contrast, or clarity.
