Claim 0:
1. A water level detection system, comprising:
a bathtub comprising a lower wall, a forward wall, a rear wall, and a pair of side walls, each of the forward wall, the rear wall, and the pair of side walls extending upwardly from the lower wall to define an interior volume, the bathtub further comprising a drain disposed in the lower wall and a drain conduit fluidly coupled to the drain;
an airtight tube fluidly coupled to the drain conduit downstream from the drain and extending upwardly from the lower wall;
a connector fluidly coupling the airtight tube to the drain conduit, the airtight tube disposed at a first axial end of the connector and a drain discharge disposed at a second axial end of the connector opposite the first axial end;
a drain valve coupled to the drain conduit downstream of the airtight tube;
a pressure sensor fluidly coupled to the airtight tube; and
a water level control unit communicably coupled to the pressure sensor, the water level control unit configured to control at least one of a height of the water within the bathtub or a temperature of the water based on pressure data from the pressure sensor.
