**Rambam (Hilchot Mikvaot 5:8 based on Kesef Mishna, as explained by Maharam Shik YD 196) explains that there's no tefisat yad adam since the water wasn't squeezed directly into the mikveh. It was just pushed or splashed into the mikveh. There's no issue of tefisat yad adam because of the movement of a person.

== Creating a Mikveh by Drawing Water ==
 
#Drawing water into a mikveh using a vessel that isn’t susceptible to tumah is nonetheless tefisat yadey adam and invalid.<ref>Rashba (Meyuchasot 231) quotes the Raavad as holding that tefisat yadey adam is an issue even with a vessel that is punctured and doesn’t hold water. Shach 201:46 and Taz 201:27 agree. However, the Meiri Mikvaot 7:3 quotes some rishonim who hold that tefisat yadey adam doesn’t apply with drawing water with a punctured vessel. The Meiri writes that this approach is incorrect because of the Mishna Mikvaot 2:6. Zichron Yosef YD 13 is also strict.</ref>

#Some rishonim hold that water drawn by a person is valid if it is unintentionally drawn into the mikveh.<ref>Raavad (Baalei Hanefesh 3:4, in the version of Rabbi Buchwald p. 150) writes explicitly that water drawn by a person unintentionally doesn’t invalidate the mikveh. The proof for Raavad is Tosefta (Mikvaot 3:3) that the mikveh filled up by the army is kosher. Rash (in ktav yad Mikvaot 2:9) agrees with Raavad. Chelkat Binyamin on seif 15 quotes Chazon Ish in understanding Rambam agrees that drawn by a person unintentionally is kosher.</ref> However, the halacha is that it is invalid.<ref>Rashba (Shaar Hamayim 5) holds that if the water is brought there by the actions of a person it is invalid even if it is unintentional. Shulchan Aruch Y.D. 201:39 codifies this opinion. The reason the water that is drawn by a person's foot is valid is because of hamshacha. This implies that it is invalid even though it is unintentional. Shach 201:46 and Taz 21:27 are both strict on water that a person unintentionally drew into a mikveh unlike the Bach 201:21 who is lenient. Chelkat Binyamin 201:250 is strict. Rosh Mikvaot n. 2 implies that he agrees with Rashba since he understands that a mikveh made by water splashing from animals is kosher but not for people, even though splashing the water only drew the water unintentionally. </ref>

#If you are trying to carry the water out of the mikveh and some of it spills back into the mikveh it isn’t considered tefisat yadey adam since it is non-beneficial to have that water spill back into the mikveh.<ref>Shach 201:46 writes that since the water spilling back into the mikveh isn’t beneficial and isn’t considered tefisat yadey adam. [http://www.hebrewbooks.org/pdfpager.aspx?req=8197&st=&pgnum=216 Lechem Vsimla (Simla 201:70)] explains the Shach to mean that it is negative that the water is spilling back. The Lechem Vsimla asks on the Shach and Chazon Ish YD 130:11 disagrees. Rashba (Shaar Hamayim 5) seems to be strict about this that even using a kli that has a hole to clean out a mikveh is considered tefisat yad adam. Shach is based on Shulchan Aruch who allowed that practice.</ref>

#Using certain types of pumps where the water doesn't come immediately is considered grama and not tefisat yadey adam.<ref>Rabbi Akiva Eiger ([https://www.hebrewbooks.org/pdfpager.aspx?req=37194&st=&pgnum=260 Derush Vchidush Ketamim]) writes that water pumped up by a person isn’t considered tefisat yadey adam since at the time of when one pulls up the pump nothing happens to the water directly.

#If the water was drawn into a mikveh using an indirect or delayed reaction according to some poskim it is valid as it wasn’t drawn by a person directly.<ref>See discussion of pump above. Rabbi Akiva Eiger in Drush Vchidush cited by Lechem Vsimla 201:145 and Divrei Yosef p. 147 held that grama doesn’t make tefisat yadey adam. Maharit 17 also writes that anything which is pushed only with a koach sheni it is considered a grama and not an issue of tefisat yadey adam. Therefore, he writes that water that was drawn from a river into a mikveh using a water mill with buckets that had holes in them is kosher. Zichron Yosef 13 also writes that koach kocho doesn’t create tefisat yadey adam. Ben Ish Chai in Hod Yosef 71 writes that koach sheni is a discussion by shechita and to avoid the opinion of the Tevuot Shor if it is a koach shelishi it isn’t considered tefisat yadey adam. Divrei Yosef p. 148 supports this approach by saying that as long as the water isn’t naturally drawn into the mikveh it is invalid.</ref>
