Pulse function needed

When replacing heads you often have dirt fall down into the fitting or the riser.
Currently to clear the line you have to Quick run it, select 1 minute and then stop it after it starts so you don’t flood your work area. It’s cumbersome and messy.
I suggest a “pulse” function which would simply give the valve a quick on and off to send a short flow of water to clear the fitting.


This seems like a good idea, but I believe the length of time depends on the length of the line, etc. Maybe an easier thing would be press to run, release to stop?
