1. A method of purging a whirlpool bathtub, comprising: providing a pump having an off condition and an on condition, the pump configured to circulate water to a basin through a water feed line;providing a blower having an off condition and an on condition, the blower configured to provide air to the basin through an air feed line;turning the blower to the on condition and the pump to the off condition; andintroducing at least a portion of the air from the blower into the pump and the water feed line. 2. The method of claim 1, further comprising outputting water from the water feed line, through a nozzle, and into the basin; wherein the air in the water feed line causes the water to be output from the water feed line. 3. The method of claim 1, wherein pressure in the air feed line is greater than pressure in the water feed line. 4. The method of claim 1, further comprising opening a check valve between the air feed line and the water feed line. 5. The method of claim 4, wherein the check valve automatically opens when pressure in the air feed line is greater than pressure in the water feed line. 6. The method of claim 4, wherein the check valve is operated between an opened and closed condition by a control system. 7. The method of claim 4, wherein the check valve is operated between an opened and closed condition by a manual switch. 8. The method of claim 1, wherein the air is introduced to the pump at a pump outlet, the pump outlet configured to output water when the pump is in the on condition. 9. The method of claim 8, further comprising outputting air from the pump through a pump inlet, the pump inlet configured to receive water when the pump is in the on condition. 10. The method of claim 9, wherein prior to turning the blower to the on condition, residual water is disposed in the pump; and wherein the air in the pump causes the residual water to be output from the pump. 11. The method of claim 9, further comprising introducing air from the pump outlet to a suction line, the suction line configured to supply water to the pump inlet when the pump is in the on condition. 12. The method of claim 11, further comprising outputting air from the suction line. 13. The method of claim 12, wherein prior to turning the blower to the on condition, residual water is disposed in the suction line; and wherein the air in the suction line causes the residual water to be output from the suction line. 14. The method of claim 13, further comprising outputting the residual water into the basin. 15. The method of claim 1, further comprising automatically purging the bathtub after the basin is drained of water. 16. The method of claim 1, further comprising manually starting the purging operation. 17. A method of purging a whirlpool bathtub, comprising: providing a pump having an off condition and an on condition, the pump configured to circulate water to a basin through a water feed line;providing a blower having an off condition and an on condition, the blower configured to provide air to the basin through an air feed line;providing a check valve between the air feed line and the water feed line;turning the blower to the on condition and the pump to the off condition, such that pressure in the water feed line is less than pressure in the air feed line;opening the check valve;introducing air from the blower, through the check valve, and into the water feed line; andintroducing air from the water feed line through a pump outlet into the pump. 18. The method of claim 17, further comprising outputting air from the pump through a pump inlet into a suction line; and outputting, through the suction line, water from at least one of the pump or the suction line into the basin.
