[C320-list] Leak appearing under holding tank

[Graeme Clark]

A good tip is to use colured food dye where you think the leak might be originating and see if it migrates as you expect. A few years ago we had pink dye in the aftvwater tank, blue dye in the holding tank and green dye where the stern gland drips in ordet to find a leak!

Although I know the holding tank was not full I pumped out at 10:00AM.  The bilge pump continued its serenade every 15-25 minutes until I left the boat at 2:00PM today.  Fresh water pump never went on.  All areas leading to the bilge are dry except the area coming from directly under the holding tank.  There is a small puddle under the port/bow corner of the tank, just below the lower hose connection.  I can't reach my hand in to feel where the wet is coming from but I see a few very small drops of moisture on the plastic hose connection of that lower holding tank hose.  Most obvious is to check that hose connection which I can't reach to try to tighten.  All other areas are dry-macerator, hoses, etc.  Any other thoughts?  Does anyone know how that hose connection works?  Catalina Direct lists it as a "female" connection but not sure which direction to try to tighten it.  I ordered long-handled pump pliers but not even sure that will reach it.  Thinking I might have to start removing hoses and loosen the tank itself to even reach down there.  Any advice would be much appreciated.  Neil Kornblatt, #973 Harmony, East Hampton, NY
