Must the same person who draws the water also sanctify and sprinkle it?
Halacha 1 states that the person who draws water does not have to be the same person who sanctified and sprinkled it — each of the three stages may be performed by different people.
Question 2
If sanctified water is weighed on a scale and diverts to a vessel midway, what is the ruling?
Halacha 5 states that if water for the ashes was weighed on a scale and one diverted it to a different vessel during weighing, it is disqualified.
Question 3
Who may NOT sprinkle the water of the red heifer ashes?
Halacha 6 rules that a deaf-mute, an intellectually impaired person, and a minor are excluded from sprinkling. All others, including women and converts, are eligible.
Question 4
If the sprinkler dips the hyssop intending to sprinkle on an entity incapable of becoming impure, what happens?
Halacha 9 rules that if the hyssop was dipped with intent to sprinkle on an entity incapable of impurity, the water remaining on the hyssop is disqualified for further use.
Question 5
After many sprinklings, a tiny drop remains on the hyssop. May one dip again and sprinkle with this tiny drop?
Halacha 10 states that although the volume has been reduced, one may dip even the tiniest remaining drop on the hyssop for continued sprinkling.
