Temporarily bypass the PVC Mixer assembly in your Hanvey Grooming Van by removing it altogether and connecting the Rinse Hose directly to the Water Temp Control valve. Watch video for demonstration
CAUTION:
In bypassing the PVC Mixer, you are removing part of the temperature regulation in the plumbing system. Always be sure to test the water temperature yourself before spraying a dog with the Rinse Hose when using this temporary bypass.
NOTE:
If the Rinse Hose leaks when hooked directly into the Water Temp Control mixer, add the orange gasket from the brass fitting on the PVC mixer to the Rinse Hose's female end to resolve.
