Zevachim8: 6
דָּם שֶׁנִּתְעָרֵב בְּמַיִם — אִם יֶשׁ בּוֹ מַרְאֵה דָם כָּשֵׁר. נִתְעָרֵב בְּיַיִן, רוֹאִין אוֹתוֹ כְּאִלּוּ הוּא מַיִם. נִתְעָרֵב בְּדַם בְּהֵמָה אוֹ בְדַם חַיָּה, רוֹאִין אוֹתוֹ כְּאִלּוּ הוּא מַיִם. רַבִּי יְהוּדָה אוֹמֵר: אֵין דָּם מְבַטֵל דָּם.
[If] blood mixed with water — if it has the color of blood it is valid. [If] it mixed with wine, we view it as if it were water. [If] it mixed with the blood of an animal or the blood of a beast, we view it as if it were water. R’ Yehudah says: Blood cannot nullify blood.
Zevachim8: 7
נִתְעָרֵב בְּדַם פְּסוּלִין, יִשָּׁפֵךְ לָאַמָּה; בְּדַם תַּמְצִית, יִשָּׁפֵךְ לָאַמָּה. רַבִּי אֱלִיעֶזֶר מַכְשִׁיר. אִם לֹא נִמְלַךְ וְנָתַן, כָּשֵׁר.
[If] it mixed with the blood of invalidated [offerings], it should be poured into the canal; [if it mixed] with draining blood, it should be poured into the canal. R’ Eliezer validates [it]. If he did not take counsel and applied [the blood to the Altar], it is valid.
