Elizabeth Hill Boone notes that there is a Maya glyph that has the meaning of "to immerse in water."

T112 appears prefixed to T581 Mol (figure 22); however, I would suggest that the presence of T12 functions as a phonetic determiner to indicate that a root with /t’u/ or /t’o/ is called for, not the typical mol reading. Mol is a month name >>water<< associations, with the same central element as the glyph for the day Muluc, called mul in several Mayan calendars (cf Chol mul >>to wet<<, Proto-Mayan *mul >>to immerse in water<<). With the T112 affix, the root t’uh or t’ub’ appears to be indicated, e.g. Yucatec t’u, t’ub- >>to sink or immerse in water<< Tzotzil t’ub >>submerge<<.
