  2. You can dip a large vessel in a mikveh that is just 40 seah specifically by doing the following: put it in the mikveh upside down, turn it over in the mikveh, turn it over again and remove it upside down. The reason it needs to be put in upside down is so that the water of the mikveh isn’t displaced and spilled out of the mikveh. The reason it needs to be removed upside down is so that the water isn’t removed from the mikveh making it less than 40 seah.[1]

  1. The Tosfeta Mikvaot 7:6 explains the procedure of how to dip a large vessel in a mikveh which is just 40 seah. The vessel is dipped in upside down and removed upside down. The Rash explains that it is placed in upside down so that the water in the vessel doesn’t become sheuvim. The Bet Yosef 201:63 explains that either the water in a vessel in the middle of the mikveh does become sheuvim even though the water is connected to the rest of the mikveh or it doesn’t but there’s a concern that as the water streams into the mikveh it’ll pause and the water in the vessel will be disconnected from the mikveh and therefore sheuvim. The Divrei Yosef p. 452 points out that this corresponds to the Rosh and Rash in Bet Yosef 201:8 whether a detached vessel in a mikveh creates sheuvim. The Rash holds it doesn’t and the Rosh holds it does. However, it is difficult that the Bet Yosef there explains the Rambam like the Rosh and here the Rambam fits with the Rash. The Chelkat Binyamin 201:870 writes that we’re concerned from the understanding of the Bet Yosef in the Rash that maybe it’ll become disconnected but not for the possibility that it is really sheuvim. However, the Rambam Hilchot Mikvaot 8:12 and Tur 201:63 explain that the reason it needs to be put in upside down is because otherwise it is going to cause water to splash out of the mikveh making it invalid.
