Why is disinfectant leaking from the cup threads of my Graco SaniSpray HP 20?
- MMatthew LaneAug 19, 2025
If you're experiencing disinfectant leaks from the cup threads of your Graco Paint Sprayer, consider the following: * Ensure there is only one FlexLiner in the Cup Support. * Make sure the Cup Lid is correctly threaded and tightened to the Cup Support, with no visible threads when tight. * Avoid flexing or pushing on the Cup Support when you evacuate the air out of the FlexLiner. * Avoid pulling down on the FlexLiner when you evacuate the air out of the FlexLiner. * Check for damage to the FlexLiner lip or the Cup Lid gasket. * Ensure the FlexLiner lip and Cup Lid gasket are free of debris. * Replace the FlexLiner if necessary.
