New, easy-to-adjust replacement float valves from Float Tec have an adjustment knob and locking nut on top so no tools are needed. When hard water lines appear, raise the water level by adjusting the knob. Multiple lines can be accumulated before tile cleaning is needed, saving money and water. Float valves come in heavy-duty brass and ABS corrosion-resistant plastic with over-sized floats for accurate water levels. Contact: 858.356.2832; floatvalvetec.com
