#202783 - 08/27/11 03:27 PM Water Line Switch
Webmaster Administrator Member Registered: 10/07/00 Posts: 3000 Loc: NY, USA	Quote: I was installing a new electrical hookup for a disposal last week and ran across this. The supply for the old disposal was run through this and then to a snap switch inside the sink cabinet. The home was built in the 1870's and I was told the kitchen was added around 1900. This switch was incorporated in the cold water supply line under the sink. I'm interested in what purpose this served at one time. Thanks in advance. Jeff (electricianjeff)

When the Insinkerator was invented back in 1927, they were afraid that folks, not being accustomed to garbage disposers wouldn't remember to run cold water and wanted to be sure that it could not turn on unless there was water flow.
