you can take clothes pins lower tip to it just barely touches gross lees, use clothes pins to hold racking cane to that level, come cleaning time i make a couple three gallons of water with k-meta potassium metabisulfite stick racking cane in solution and fill it up with the potassium metabisulfite , cove racking cane tips with plastic baggies, come time to use again turn pump on and pump out solution and your set to do again, when done fill with potassium metabisulfite again and recover tips

what i was talking about is when bottling you have a valve to push to keep from over filling your wine bottles, i put a valve on my splash rack vacuum line to keep from over filling my carboys, feel free to ask questions,
