Sun-Mar Excel NE Composting Toilet


Pros: None

Cons: Dosent work, handle on drum breaks, plastic cracks after about 20 months, fan dies every 6 months, flies almost impossible to stop, doesn't drain...

 We purchased the SunMar Excel NE from Home Depot for around 1370.00 CAD! Wow. we thought we really had something great. A few years down the road, and we now know that no matter what you do it never really composts. It absolutely needs a fan or it will stink you out (so much for the NE - No Electricity). The drain is constantly getting clogged from debris that falls through the very primitive screen in the drum. Urine drips into the drawer dispite everything we have tried to stop it. the plastic gets brittle and cracks around the top of the toilet. And the very worst of it is when you have to empty it - Oh My God. The drawer sits it pee and debris that has fallen through to the bottom and created the most vial soup you have ever smelled, it drips on the floor when you pull it out. then you rotate the drum and the crap doesn't all come out at once, some gets pinched off by the drum smearing crap all aound the drum and rolling it right up to the toilet seat. i could go on, but there isn't much point. We are ridding ourselves of this - never to buy anything Sunmar again. I think the design on this is so bad that I have no idea how it could be approved anywhere.
Seriously, we read some bad reviews on this before we bought it but wanted it so bad, we convinced ourselves that Home Depot wouldn't sell it if it wasn't goo. We where wrong. I have nothing to gain here - just hoping to save someone else the huge chunk of money and regret - a mistake we learned the hard way.
Sun-Mar Excel NE Composting Toilet

The success of the Excel design meant that a three chamber unit could be specifically designed for those with NO continuous 110 volt supply. First launched in 1981, the Excel NE has long been the standard toilet for those living off the grid. A 1998 redesign gave the unit a rounded look, and recessed the drum handle. The Excel NE has no fan or heater. Odorless operation is achieved by a 4" vent mounted at the top rear of the unit which acts like a chimney on a wood stove. For good air movement the vent should be installed vertically and to 2-3 feet above the peak of the roof. The optional 12 Volt Fan should be installed if you need to install the toilet with any bends in the vent. No more than 2 45° bends are encouraged, even with the fan. If the Excel NE is used residentially or heavily, or is in a place which is subject to downdraft, the optional 12 volt fan should be installed in the vent stack. This fan draws 1.4 watts and can be powered by a solar panel and 12 volt marine battery. Evaporating capacity on the Excel NE is variable, so the 1" drain at the rear should be connected to an approved drain pit, container, or other facility Please click here for more information on handling excess liquid.
