And / Subject

Are these two sentences grammatically correct?

Should I be using 'is' or 'are'? What is the difference in meaning when I use 'is' vs 'are'?

1. If frequent inspection and maintenance is not performed, the potential of clogged pipe increases. (What is the subject here?)
2. If frequent inspection and maintenance are not performed, the potential of clogged pipe increases. (What is the subject here?)

Thanks

You may choose either 'is' or 'are'. With 'is' you are conceptualizing 'inspection and maintenance' as a single, combined procedure. With 'are' you are conceptualizing the two as separate operations.

  • You may choose either 'is' or 'are'.
  • With 'is' you are conceptualizing 'inspection and maintenance' as a single, combined procedure.
  • With 'are' you are conceptualizing the two as separate operations.
  • The subject of the if -clause is 'frequent inspection and maintenance' in both sentences.
