Purchasing Low-Consumption Toilets
and Toilet Replacements

With few exceptions, Washington State law requires 1.6 gallon-per-flush (gpf) toilets and 1.0 gpf urinals for all new construction and replacement situations. These toilets are called low-consumption, low-volume or ultra low-flush. Since all low-consumption toilets do not perform equally, Seattle Public Utilities would like to help customers make informed purchase and replacement decisions. This information is not a substitute for the professional judgment of a licensed plumber or engineer.  It is intended as a guide so you are better informed for discussions with your plumber or retailer.
