Garden Hose Timer
Ever set the water sprinklers late in the day and forget they were on when you went to bed? The next morning when you look out the window the neighbor kids are playing in the curbside river running down the street. Hose-end timers can fix such costly waste. Hook one up and set it to allow the water to flow for a prescribed length of time. Some models even allow you to set a weekly schedule.
