Electric macerating toilets need little maintenanc
The first thing you should do is trace all the plumbing to and from the toilet and to and from the tank. In fact, you should find everything in every system on your boat...'cuz an emergency is NOT the time to START looking for breakers, fuses, or thru-hulls. And read ALL The manuals, so you know how things work. If you don't have manuals, get them from the mfrs. Basic operation of your electric toilet: Make sure the breaker is on and the intake seacock is open before attempting to flush it. Don't flush anything that you haven't eaten first except quick-dissolve toilet paper. Close the seacocks before leaving the boat. Read the owners manual...if you don't have one, get one from the mfr. There's more, but that's enough to get you started. It's the holding tank that needs the most attention and maintenance (btw...the toilet DOES flush into a tank, not directly overboard? If not, you'll have to install a tank 'cuz it's legal to flush a toilet directly overboard). Keep an eye on the level in the tank, 'cuz allowing it to overflow out the vent is a major no-no. Check the vent regularly and backflush it every time you pump out and wash the boat...a blocked tank vent can create all of kinds of disasters, from a pressurized tank that erupts back up through the toilet or even bursts to a crack tank during pumpout. Rinse the tank after each pumpout. To prevent odor out the vent, use Odorlos or Raritan K.O. according to directions on their bottles. That's the basics...you might want to check out the link below for the rest.
