What is a "suds saver" or water saver?
A suds saver was an option on many washing machines at one time. The suds saver allowed to save the wash water from the first load of wash to reuse for the next load or loads. Suds-savers reuse most of the sudsy wash water for a second load. By beginning with the cleanest clothes and reusing wash water for at least one load, suds-savers can cut water use by 30-50%.
