We installed the Centrex 2000 last fall and just moved the compost to the finishing drawer a year later. The unit works better than we expected. Our camp is on a hill and the cost of a septic system was in the $8000.00 range. We use our camp every weekend and for extended weeks in the summer and fall. The unit performs perfectly with no odor and with the 510 toilet, very little water. We installed the unit in a couple of hours. The instructions were precise and easy to follow. Thanks for making our camp a place we can enjoy for years to come.

After 10 years of faithful service, it was time to retire our WCM. We had been "stretching" the limits of the design - with a little more traffic than it was intended to handle. Since it had come to be in nearly continuous use, we always had to consider the WCM composter limitations when having guests visit. The answer was to upgrade to a Centrex 2000, which has added capacity, and can handle all the traffic we expect.

The one-man installation on 08/24/02 went quickly and smoothly - out of the box, the Centrex 2000 slid easily into place on the concrete pad we had poured for the WCM over 10 years ago; with its lower profile, it looks even better, and allowed for a true 45° pitch for the waste pipe. I had planned a complete replacement of the 3" soil pipe from the toilet flange to the Centrex 2000. With all fittings on hand, the waste pipe install was very straightforward. Based on the design drawings, and the space limitations on site, my initial concern had been routing the vent pipe, which had to cross in front of the bio-drum access door to connect with the existing vent pipe. Using only the 2" pipe and fittings provided in the installation kit, I was able to run the vent without blocking the access door.

Start to finish, it took about 2 hours to complete the installation of the Centrex 2000 and adapt it to the existing plumbing. We look forward to many more years of use.

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.

Being an island cottage owner, the Centrex 2000 works great. We have had it in operation for 2 summers now and the system has worked extremely well. We have absolutely no regrets! We have recommended the system & now there are several more installed on our island.

We installed the Centrex 2000 last summer in our cottage in Minaki, ON. Over the years we tried propane and chemical toilets and neither worked. We are so pleased with the composting toilet. It is great.

We are really pleased with our compost toilet. (We have the one pint flush). Easy to install, very little maintenance and no problems so far. The township inspector gave it the "thumbs up" as well. We would recommend it to anyone.

The Oberndorfers came to visit the Sun-Mar showroom and dropped off some pictures of their installation. The unit photo shows the vent pipe coming out of the front, and the venting photo gives a good idea of the vent run.
