The Sundance and Jacuzzi JHT 2007 diverter knob is designed for compatible diverter valve applications where the visible control knob needs to be replaced. Diverter knobs are useful because they provide the user-facing grip and control point needed to direct water flow comfortably and accurately.This replacement is especially useful when the original knob is cracked, loose, discolored, or missing, making the diverter harder to operate or leaving the valve looking unfinished. Replacing the knob can be an easy way to restore both function and appearance without replacing the full diverter assembly.It is a practical service part when the valve still works but the control point the user touches needs to be renewed. Sundance and Jacuzzi JHT 2007 diverter knob Helps restore the user control point for the compatible diverter valve Useful when the original knob is cracked or missing Supports easier diverter operation and a cleaner finished look Improves visible trim without replacing the full valve
