         8 . The PCB of  claim 1 , wherein the valve is a trapway valve. 
     
     
         9 . The PCB of  claim 1 , further comprising:
 a first sensor input corresponding to a first automatic seat timing;   a second sensor input corresponding to a second automatic seat timing, wherein the control circuit is configured to select the first automatic seat timing when a sensor is connected to the first sensor input and second the second automatic seat timing when the sensor is connected to the second sensor input.   
     
     
         10 . The PCB of  claim 9 , wherein the first automatic seat timing causes the seat to automatically close after a first time period, and the second automatic seat timing causes the seat to automatically close after a second time period. 
     
     
         11 . A toilet comprising:
 a water supply valve;   a solenoid configured to open and close the water supply valve;   a printed circuit board (PCB) for controlling the solenoid, the PCB including:
 a first input corresponding to a first flush volume; 
 a second input corresponding to a second flush volume; and 
 a control circuit configured to open a valve for a first time period corresponding to the first flush volume when the first input is connected and open the valve for a second time period corresponding to the first flush volume when the second input is connected. 
   
     
     
         12 . The toilet of  claim 11 , further comprising:
 an actuator configured to receive a user instruction.   
     
     
         13 . The toilet of  claim 12 , wherein the first input corresponds to a first light for the actuator and the second input corresponds to a second light for the actuator. 
     
     
         14 . The toilet of  claim 11 , wherein a connector is connected to the first input to select the first flush volume. 
     
     
         15 . The toilet of  claim 11 , further comprising:
 a third input corresponding to a third flush volume.   
     
     
         16 . The toilet of  claim 11 , wherein the water supply valve is a flush valve opened by a drive mechanism. 
     
     
         17 . The toilet of  claim 11 , wherein the valve is a trapway valve opened by a spring. 
     
     
         18 . The toilet of  claim 11 , further comprising:
 a first sensor input corresponding to a first automatic seat timing;   a second sensor input corresponding to a second automatic seat timing, wherein the control circuit is configured to select the first automatic seat timing when a sensor is connected to the first sensor input and second the second automatic seat timing when the sensor is connected to the second sensor input.   
     
     
         19 . The toilet of  claim 18 , wherein the first automatic seat timing causes the seat to automatically close after a first time period, and the second automatic seat timing causes the seat to automatically close after a second time period.
