The 511 Plus Ultra Low Flush Toilet is the low profile version of the 510+ toilet, designed for use with the Centrex 1000, Centrex 2000, and Centrex 3000 Central composting toilet systems by Sun-Mar. Multiple low flush toilets can be used with the centrex systems if necessary.
The 511+ offers a low profile for use when extra height is needed to allow the toilet to gravity feed to the composting unit.
Using about one pint per flush, these ultra low flush toilets provide all the advantages of a flush toilet while minimizing water usage. They are ideal for use with Sun-Mar Central Composting Systems, but can also be used with holding tanks, overloaded septic systems, and in RV's.
A simple foot pedal flush opens the water valve and gate when pushed down, and fills the bowl with water when lifted. After flushing, a small amount of water is held in the toilet bowl which is sealed by a self-cleaning ball valve and teflon seal. Even gravity-fed water from a roof tank is sufficient to flush a 1 pint flush toilet. In winter they can be flushed manually using a container if necessary.
The 511+ ultra low flush toilet has a regular sized toilet seat. For Sun-Mar installations, we recommend the 510+ as the unit of choice as it has the size and appearance of a "regular" toilet. They come complete, except for the required Floor flange, (purchased separately).
