Waterless Co. LLC has introduced a full ceramic urinal, Model No. 2102 SIERRA™. The Sierra model has a ceramic glazed interior 2-inch drain line. The company says it is the only non-water using ceramic urinal currently on the market. No O-rings or housing to accept the trap cartridge are needed. The fixture weighs about 43 pounds. Waterless No-Flush™ urinals do not require any water or any mechanical parts for flushing. These urinals can save 45,000 gallons or more of potable water in a year, the company said.
