Where can I find a kitchen faucet that stays in spray mode after turning the water off and turning it back on?
We have a Kohler Model K-10433 that has a pushbutton near the spray head.  Pushing it one way gives a stream and pushing it the other way gives a spray.  It will remain in whatever position it was in when the water is turned off. However this unit was installed back in 2009 so I don't know what Kohler may have available now.
