There is some nasty smelling water in the bilge. Not clearly holding tank water but it may be.
Is their some dye I can put in the tank to find out.
What is it called where do I get it.

Do you think food coloring would work?

You can also slightly pressurize the empty Holding tank (2-3 psi) and check the area under suspicion with a mix of dishwashing detergent/water, then looking for the generation of 'soap bubbles'.

DO NOT PRESSSURISE YOUR HOLDING TANK TO 3 PSI.

Life is likely to get interesting and messy if you do this. Assuming the tank has a side 2' x1' the force created by a tank overpressure of 3 psi is 12 x 24 x3 is 864 lbs; do you really want to see if your tank can withstand this sort of force. :eek:
