When you use RO/DI water should you still use Prime to be on the safe side or not ?

Don't mean to hijack but if your city water is very clean can you use Prime instead of RODI? I did a TDS a long time ago and it was very low, don't exactly recall what it was, should do it again.

Thanks, I didn't know what the exact level is. I will have to measure again. What is average in the US for TDS in tap?
