Above is a picture of an actuator I have that controls how much water goes to my slide. I realize I would much prefer to be able to control it with a manual valve because the actuator only gives me two options (large amount and smaller amount) of water to the slide. And water is often bouncing off the slide onto my landscaping even on the low option, so it would be easier if I could manually adjust the valve.
How would I take off the actuator and put on a handle that I could move around while adjusting the water to the slide. I'm not very handy, but am thinking it is probably not too difficult. What brand of handle should I get?
