A mikveh acquires a sulfurous smell but its color remains clear. Is it still valid?
Halacha 1 explicitly states that a mikveh is not disqualified by changes in taste or smell — only a color change disqualifies it.
Question 2
Which of the following CANNOT make a mikveh valid even if it completes the 40 se'ah?
Halacha 4 classifies fruit juice as a 'neutral substance' that neither validates nor disqualifies a mikveh. Only substances in the validating category (snow, hail, ice, salt, flowing mud) can complete a mikveh.
Question 3
Olive-basket washing causes a mikveh's water to change color. Is the mikveh disqualified?
Halacha 7 specifically rules that washing baskets used for olives or grapes in a mikveh — even though the water's color changes — is acceptable and does not disqualify the mikveh.
Question 4
Wine falls into a mikveh and changes the color of its water. How can the mikveh be restored to valid status?
Halacha 9 states that when wine or other substances change the mikveh's color, one must wait until rain descends, adding enough water to restore the original water color.
Question 5
A mikveh's color changes on its own with no foreign substance having fallen in. Is it disqualified?
Halacha 12 explicitly rules that when a mikveh's color changes on its own accord without anything falling into it, it remains valid — disqualification only occurs when a foreign liquid causes the change.
