The mikveh: review quiz
Check what you've learned about the mikveh itself: rain water, the required amount, and the otzar pool according to Chabad custom and other poskim. Each answer points to the page in Family Purity where it's explained.
Chapter 9, What Is a Mikveh?, is in the printed Family Purity and is not online yet. For a practical question, please ask your rav or ask Rabbi Jacobs.
