Prep gun setup

I don't think you really want to have your guns turn off every time you let go of the trigger. Most setups use a flow switch to activate a timer which turns the guns on and then shuts them off after a short period of time.
 
It's simple to do - there's an inline flow switch you would install downstream of the unloader along with city pressure to activate the switch when the trigger is pulled, then run power from that to an off-delay relay. Like Washmee said, you probably don't want it starting/stopping every time, but with a delay you can control it to stay on between cars on a busy day.

Thanks. Do you have a link to that flow switch?
