Sun-Mar Centrex 3000 NE (Non-Electric) High Capacity Central Composting Toilet System
The Centrex 3000 NE High Capacity Central Composting Toilet System is the largest central composting toilet system in the Sun-Mar lineup. Capable of handling a family of 5 full time or up to 8 for part time seasonal use, this system is a real giant in the industry and is perfect for heavy cottage or medium residential use.
When used seasonally by up to 8 adults, compost will normally only need removing annually each spring. In residential use compost will have to be extracted more frequently.
Centrex central composting systems offer all the benefits of modern waste composting systems while keeping the look and feel of a more traditional bathroom.
Sun-Mar Centrex 3000 NE Continuous Flow Design
The Centrex 3000 NE utilizes a continuous flow design for very heavy cottage or medium residential use. With a continuous flow system, rotation of the drum moves compost along the larger and longer 3000 series drum, before it drops automatically into the collection housing at the end of the unit. Under normal operating conditions the drum will not have to be turned backwards for emptying.
All Centrex 3000 series units are supplied with a 1" drain hose which should be connected to the 1" drain at the bottom left of the unit.
The Centrex 3000 NE may be used as a wet or dry system depending on your available hookups and needs.

QUESTIONS & ANSWERSAsk a Question
Do any of these composting toilets use water? Also could you use a more traditional toilet but one that is a bit more eco friendly?
The Centrex does use water, if you use the get the low flush toilet. For the Centrex 3000 you would need to get the Centrex toilet. There are quite a few options above the "Add the Cart" button.
Bought this unit a couple years ago for a cabin in north Idaho. Has seen both occasional winter use, and constant summer use. As long as you follow the instructions to crank the tank once a week when in use and put some bulking material in as indicated, it works great. Saved a ton of money over putting in a full blown septic system. The blower and piping keep the bugs doing their job and the smell away from living spaces. My only complaint is that the toilet itself is a bit flimsy. The plastic base flexes a lot when you sit on it, especially for large 200lb+ males. If they improved the toilet quality, it would be perfect.
