Query: Get a time based timer.

This product does not work well with variable water flows. Underlow pressure it tends to not turn off. It is just not reliable enough to count on, and if you have to go out and check to see if it worked, what is the point? I think you will be better off with a timer that works with a spring, like an egg timer rather than one that works via water flow.
