Low Flush Systems

For those that want a traditional type of toilet in the bathroom, Centrex family low flush systems are ideal. Centrex family low flush systems are designed for use with a Sealand 1 pint flush toilet. The Sealand in the bathroom is connected by a standard 3" plumbing pipe to the composting unit which is below the toilet and normally within 15-20 feet.

Electric or Non-Electric

For those with continuous 110 Volt power, an electric unit is suggested. Electric units feature a 370 watt 120V themostatically controlled heater in a sealed compartment beneath the unit. Odor free operation is maintained by a standard 30 watt turbo fan directing air up a 2" vent stack. If you have no electricity, then a non-electric (NE) unit is the right selection. 12 Volt fans are supplied with Centrex 2000 and Centrex 3000 series non-electric units but are not normally needed for cottage applications, unless the system is used heavily or is particularly subject to downdraft. AC/DC units are dual vented units with both a 2" and 4" vent for those who expect to have 110v power in the future, or are running a generator for 12 or more hours per day.

Unit Capacity

Three differently sized units, the Centrex 1000 (batch unit), Centrex 2000 ( batch unit) and Centrex 3000 (continuous unit) are available for use with 1 pint flush toilets. The selection should be based on both whether the unit is used seasonally or residentially, and the number of people that will be using the unit. Typically, the Centrex 1000 is suitable for light to medium cottage use, the Centrex 2000 for medium to heavy cottage use or light residential use, while the continuous flow Centrex 3000 series is suitable for very heavy cottage use, or medium residential use. As with all units, advertised composting capacities can be doubled for short periods.

All central low flush systems are supplied with a 1" drain hose which should be connected to the 1" drain at the bottom left of the unit. Liquid output should be collected or drained into an approved facility.
