Q:Can we send toilet paper down into this unit? Does it have to be special toilet paper?

Answer This Question

A:  Hello Scot, Thank you for your question. All Sun-Mar composting toilets and composting systems, including the Centrex 2000 NE, will easily handle toilet paper. In fact, you can use conventional 2 ply toilet paper with all of these systems and do not need to go out and buy any expensive or specifically "bio-degradable" type of toilet paper. Sun-Mar composting systems can typically breakdown conventional toilet paper in a matter of days. We hope you find this helpful, however please do not hesitate to contact Sun-Mar, Toll Free at 1-888-341-0782 Ext. 1032 (Mon - Fri: 9am - 5pm EST) should you have any additional questions, we are happy to help. Thank you.

    The only way to go!
    The Sunmar 2000. Is the perfect alternative to the 25000 dollar septic system! I just purchased my 2nd unit. The first 1 lasted 15 years. The new unit is slightly different from my original but the improvements are very welcome. I highly recommend this to anyone.

      Sun-Mar composting toilets
      We have had one at our cabin since 2002. To keep it working properly, you need to add bulking mix and a microbe mix to aid composting. Sun-Mar says you must use their products but they are hard to find and then you will have to have them sent to you from a dealer somewhere--not available in our city. I do not understand why they think composting enzymes for another brand of composting toilet will not work just as well. The composter works well but getting the additives is a real pain--and extra cost!

          Environmentally friendly & cost effective
          We bought ours almost 25 years ago now thinking about replacing it! And yes you can use composted human waste in your garden! We have a cabin in the woods on an island in northern Ontario it’s been perfect and way better than paying $20000 for someone to bulldoze trees and rocks to create a septic field!

            Would not recommend this, unless you have a VERY accessible crawlspace. I mean like 6 feet, so this can be higher up as being on all 4s to clean this thing is agony. I really wish I went with the bucket version that you walk outside every time it fills.

              Love it!
              We've had an 2000NE in our summer home for four years now (it's on an isolated island in the north). We---especially my wife and grandchildren---love having just a small odour-free toilet in the interior washroom. Of course the stinky old outhouse is long-forgotten. The installation was somewhat complex---(a) pouring a levelling concrete pad under the house, (b) running a 4" vent up through two floors and the roof, (c) creating an evaporating mound for the French drain, and (d) running a water line---but well worth it. It certainly was easier than building a new outhouse and pit. When the septic system on our southern acreage eventually fails we'll be replacing it with a Centrex unit.

                This does not come with the toilet itself, which actually does take water. Doesn't say complete toilet system minus the toilet anywhere. Please fix this.
