If you have a macerator pump, that means you should probably have a Y valve
somewhere and a deck pumpout fitting. The Y valve will select which way you
can discharge the waste. Within three miles of shore, you cannot legally
pump the waste overboard, so you'll have to set the Y valve so that the
waste can be pumped out through the deck pumpout. You should be able to
locate it by it's labeling, if not, just open and sniff. It should be easy
to find!

If your boat only has a macerator pump for discharging overboard, I'd
imagine you need to upgrade the system.

I recently purchased a used 1998 27 foot ProLine walk around with cuddy
cabin and an electric toilet. We need to empty the holding tank. I have
no documentation for the boat. Are there valves that need to be opened?
If so where are they? Do I turn on the macerator pump? Do I need to run
the electric toilet. Could someone let me know the procedure?
