Should I have been told that the plumbers pipe camera is used in raw sewage before he scoped my rainwater collection system with it?

I called a local plumbing company and requested to have my downpipes scoped as I believe there is a leak in one of them where they go down and connect to the 100mm. When the plumber arrived he told me that his camera was too big for the downpipes which was the first time this was mentioned to me. He said he could put it in the headpipe of my charged rainwater collection system to see if he can find any leaks in the section viewable from that point. I agreed as I had already waited a two weeks for the call out and was eager for some answers.

It dawned on me after they left that the camera used was designed for 100mm pipe and thus probably mostly used in raw sewage.

Is it reasonable to expect that I should have been told about this before agreeing to have the equipment used in my drinking water system?

This decade interim coaches have a 43% win rate in their first match. Our win rate this season is 13.5%.

If we sack a coach every week and get a little luck we can still make finals.
