A macerator toilet is a type of marine toilet that uses a macerator pump to grind waste and move it to a black water holding tank. The macerator pump is integrated into the ceramic toilet and is typically operated by a button or pump handle. The holding tank can then be emptied using a diaphragm pump at sea. This system is commonly found on boats and yachts, and there are various ways to plumb the toilet and pump.

| How to use it | After using the toilet, press the button to start the macerator pump to pump the waste into the holding tank. Then, empty the tank using a diaphragm pump at sea. |
| Pros and cons | The Boat Projects system is popular but there are other systems that work differently. For example, the Ericson yachts system sends waste to the tank or directly out through the skin fitting. |
| Pumping options | There is a large Y-valve in the hull for selecting between dockside pumping or overboard discharge. |

The macerator pump grinds waste and moves it to the black water holding tank
The macerator pump, integrated into the ceramic toilet, grinds the waste and then moves it to the black water holding tank. Once you've used the toilet, you press a button to start the macerator pump, which pumps the waste into the holding tank. You can then empty the tank using a diaphragm pump at sea.
Some boats have a Jabsco toilet with a pump handle and a holding tank with a macerator. The holding tank holds the waste. There is a large Y-valve in the hull, which is used to select between dockside pumping or overboard discharge.

The toilet pump can send waste to the tank or directly out through the skin fitting
The macerator toilet works by using a pump to grind waste and then move it to a black water holding tank. The pump can send waste to the tank or directly out through the skin fitting. This is done by pressing a button to start the macerator pump, which pumps the waste into the tank. The tank can then be emptied using a diaphragm pump at sea.
The macerator pump is integrated into the ceramic toilet and is used to grind the waste and move it to the holding tank. The holding tank holds the waste and can be emptied at sea. The Y-valve in the hull is used to select between dockside pumping or overboard discharge.
It is important to note that if the vent and pump-out line are cut and capped, the toilet cannot be used as a pump-out or a regular porta-potti. The fittings on the back side of the toilet should be capped instead to ensure proper function.

The Y-valve in the hull is for selecting between dockside pumping or overboard discharge
The Y-valve is a large valve that is located in the hull of the boat. It is connected to the holding tank, which stores the waste from the toilet. When you use the toilet, the waste is pumped into the holding tank. You can then choose to empty the tank using a diaphragm pump at sea, or you can connect to a dockside pumping station to empty the tank.
The Y-valve makes it possible to select between these two disposal methods. If you are at sea, you would use the overboard discharge option, which pumps the waste directly out through the skin fitting of the boat. If you are docked, you can connect to a dockside pumping station and use the dockside pumping option to empty the tank.
The Y-valve is an essential component of the macerator toilet system on a boat, as it provides flexibility in waste disposal. It allows boat owners to choose the most convenient and appropriate method for disposing of waste, depending on their location and circumstances.

The water inlet device delivers clean water to the inside of the toilet bowl
Once the waste has been deposited in the bowl, the macerator pump, which is integrated into the ceramic toilet, grinds the waste and moves it to the black water holding tank. This tank holds the waste until it can be emptied, either directly overboard or into a waste tank, which is then emptied using a diaphragm pump at sea.
There are a few different systems for macerator toilets on boats, and some boats have a large Y-valve in the hull, which is used to select between dockside pumping or overboard discharge. Some boats also have a Jabsco toilet with a pump handle, which sends the waste directly to the holding tank or overboard.
