Western Oregon | I have an incommand and directcontrol in my sprayer. When refilling I sometimes shut off the sprayer. When everything is quiet I can hear the pwm valve (I think) humming. I can switch the rate to manual and turn it down to where the humming goes away. Problem is I sometimes forget to turn it back up, and it takes a little for the rate to catch up on auto. Does it hurt to let it sit and humm until I start back up 10 to 20 minutes later ? | |
