	*The [http://www.hebrewbooks.org/pdfpager.aspx?req=8785&pgnum=116 Raavad Baalei Hanefesh p. 116] (Bookwald 3:4 p. 147) quotes an opinion who explains that water drawn by a person is a form of sheuvim. He explains that in the Torah it never says that drawn water is invalid if it is placed in a vessel, it is invalid anytime it isn’t natural like a spring, whether the water is drawn with a vessel or by a person. From the last versions of Raavad it is clear that originally he treated the water completely like sheuvim that invalidate a mikveh with 3 lugin. However, in his conclusion he held that it is only invalid if majority of the mikveh is from this water, and it isn't completely like sheuvim. The Rash (Mikvaot 2:6) writes that the water a person draws is like sheuvim. Rashba (Torat Habayit Shaar Hamayim 5, p. 494), Rosh (Mikvaot 2:6), Rambam (Pirush Mishnayot 2:6), Trumat Hadeshen 254, Bet Yosef 201:15(4) agree that tefisat yedey adam is sheuvim. The translation of the Rambam in the Mechon Hameor edition of Rambam p. 564 fnt. 15 this point is even clearer. Mishnah Achronah 2:6, Tiferet Yisrael (Boaz 2:5), Aruch Hashulchan 201:120, Chelkat Binyamin 201:270, Chazon Ish YD 130:9 explaining the Ramban, Rash, Rosh, and Rashba.		*The [http://www.hebrewbooks.org/pdfpager.aspx?req=8785&pgnum=116 Raavad Baalei Hanefesh p. 116] (Bookwald 3:4 p. 147) quotes an opinion who explains that water drawn by a person is a form of sheuvim.

The translation of the Rambam in the Mechon Hameor edition of Rambam p. 564 fnt. 15 this point is even clearer. This is also the opinon of Mishnah Achronah 2:6, Tiferet Yisrael (Boaz 2:5), Aruch Hashulchan 201:120, Chelkat Binyamin 201:270, and Chazon Ish YD 130:9 explaining the Ramban, Rash, Rosh, and Rashba.
	*The Raavad himself says he doesn't think it is sheuvim but nonetheless invalid if you have intention to draw the water into the mikveh. Rabbi Akiva Eiger (Bookwald edition p. 149) thinks this is a deoritta invalidation, while the fuller text seems to indicate that is only rabbinic (p. 149 fnt. 18).		*The Raavad himself says he doesn't think it is sheuvim, but nonetheless invalid if you have intention to draw the water into the mikveh.

	*Zichron Yosef YD 13 explains that water that is drawn by a person is considered havaya al yadey dvar hamekabel tumah since a person is mekabel tumah. The invalidation is a derivation in Zevachim 25b. He explains that it is considered havaya al yadey dvar hamekabel tumah even if you’re not touching the water. His proof is that the Rosh Mikvaot 5:5 codified by Shulchan Aruch 201:48 writes that a person holding a board on which the water flows into the mikveh is havaya al yadey dvar hamekabel tumah. Taz 201:58 agrees that a person is mekabel tumah and would create this invalidation. This is evident in Mishna Parah 6:4. However, according to the rishonim and achronim above this isn't the only invalidation of tefisat yedey adam.		*Zichron Yosef YD 13 explains that water that is drawn by a person is considered havaya al yadey dvar hamekabel tumah since a person is mekabel tumah.

	**Yet, according to the Rambam (Mikvaot 6:2 as pointed out by the Bet Yosef YD 201:48) this invalidation of havaya al yedey dvar hamekabel tumah is only true for mayim chayim and not a mikveh.		**Yet, according to the Rambam (Mikvaot 6:2 as pointed out by the Bet Yosef YD 201:48) this invalidation of havaya al yedey dvar hamekabel tumah is only true for mayim chayim and not a mikveh.
