Low Flush Systems
For those that want a traditional type of toilet with water flush in the bathroom,
Centrex family low water flush systems are ideal. Centrex family low water 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.
