Questions & Answers about Коль скоро заявку на ремонт приняли, перепад давления запишут.

What does коль скоро mean here? Is it common in modern Russian?

Here коль скоро means since, seeing that, or now that.

In this sentence, it introduces the reason/background for the main action:

• Коль скоро заявку на ремонт приняли, ...
• Since the repair request was accepted, ...

A few notes:

• It sounds bookish, formal, or a bit old-fashioned in everyday speech.
• In modern conversational Russian, people would more often say:
  • раз
  • поскольку
  • раз уж

So a more neutral version might be:

• Раз заявку на ремонт приняли, перепад давления запишут.

Why is there a comma after приняли?

Because коль скоро introduces a subordinate clause.

The first part:

• Коль скоро заявку на ремонт приняли

is the dependent clause, and the second part:

• перепад давления запишут

is the main clause.

Russian normally separates this kind of clause with a comma, just as English often does with since, because, or now that clauses.

Why is in this form?
