Just bought a new/used boat.... it is bigger than my last, it is outboard vs inboard, it has livewells, bait boxes, and a marine head. I have lots of questions and unfortunately dont know the proper verbage for some of these things.... to start, I have a marine toilet....a Dometic. It looks as if it is a portable one because it does have a place to pour the chemical in, it has a pump used before I pull the knob to flow into the "holding tank"....HOWEVER, this boat has many upgrades, and the toilet looks to be plumbed with hoses going in to the wall and the starboard side has a waste removal cap. I dont know how to work any of this....where does the water come from to actually flush .... since there is a waste cap, is there a larger "waste holding tank" in the hull that that the waste should be moving into and needs to be emptied?
We'll start with this ... remember, I have many more!

You and I may be in the same boat...so to speak. Also have a new to me Wellcraft (2010) and it sounds like the same "marine" toilet setup. Are you sure there is a holding tank other than the little one on the lower half of your Dometic? If there is a real holding tank, there would need to be some pumping mechanism to move waste into the holding tank, and of course to pump it out again. If yours is like mine, it is set up so the waste can be vacuumed out. Thus the plumbing from the lower unit of the Dometic toilet. Mine goes to the gunnel. This is just so you don't have to remove the little tank on the toilet and go dump it. To call these a "marine head" is not really accurate. They are still portable toilets that are plumbed for vacuuming vs remove and empty. The water to flush...you have to fill the top part of the toilet with water. A real marine head is plumbed for this as well. If your setup is like mine. You must remove the unit and fill it, or bring a hose to fill it.

Hope that was helpful.

Could you ask the person you bought the boat from ?
