The Centrex 2000 Central Composting Toilet System is a step up from the centrex 1000 in every way. It provides longer composting cycles, larger waste storage volume, and the ability to use as a wet or dry system! The Centrex 2000 is designed for medium to heavy seasonal or light residential use.

QUESTIONS & ANSWERSAsk a Question
Can the Centrex 2000 be placed horizontally, above-ground, in a separate room from the toilet, OR must it remain underground, below the toilet?
If you are installing a 510 low flush toilet it can be above ground but at plumbing grade from the toilet. If you are looking at the waterless options, the Centrex system must be directly below the toilet.
How will this hold up in the Winter months? I live in a small cabin. I was going to place it under the cabin in the back. But not sure how it will hold up with cold temps... Thank you for your reply.
In the winter months, the composting unit has to be kept above 55F in order for the compost unit to actively compost. For limited use in cold temperatures, you can use the unit as a holding tank as long as there is enough space in the drum.
Itself the product is wonderful, the boxes come large and on a 3rd party company , the crank is a little extreme, old school car without power steering. having the tank at the bottom of home instead of in the home is a really good ideal for the ones that want a normal toliet but wanna go compost. It’s outside with plumbing , not a lazy man toliet. Crank that super toliet hey !
It was very easy to order which I did on September 9 it is now January and I have not received my toilet. First it was the coronavirus now it’s a snow storm. I sure hope this toilet can handle all this
So far, It is working good. No smell and easy to operate/maintain.
Toilet is a little low to the ground is there a higher one I can purchase. Overall the system works well.
We are thrilled with our Centrex 2000. As our cottage is built on rock, a septic system would have been very expensive. The Sun-Mar system is much more affordable and environmentally friendly, which is important to us.
