1. An embalming machine comprising:
a reservoir;
a tube extending from a lower portion to an upper portion of the reservoir, wherein the tube provides a pathway for fluid to travel to the reservoir; and
a port at an end of the tube adjacent to the upper portion of the reservoir, wherein the port is configured to dispense the fluid traveling through the tube into an interior of the reservoir;
an inject outlet;
a pump operable to pump fluid from the reservoir and to the inject outlet and/or the port;
a mix solenoid to which fluid flows from the pump to be directed to the tube to dispense fluid from the port into the reservoir to facilitate mixing of fluid in the reservoir;
a pressure regulator having a pressure relief bypass along which fluid flows to route fluid flowing from the pump back to the reservoir, the pressure regulator operable to control a proportion of the fluid routed to the reservoir via the pressure relief bypass to control a pressure of the fluid flowing from the pump;
a user interface configured to receive a pressure setting input for the embalming machine to cause the pressure regulator to set the proportion of the fluid flowing in the pressure relief bypass.
