I'm working on a hot tub I just acquired and I opened up the diverter valves. Trying to figure out which position is open/closed. When I popped the handle off and unscrewed the cap, this is what I saw:
Oddly, the black tube leading down to the ball valve is open on both sides to air, like I can see my hand by looking through the holes in the tube. Is that how its supposed to be?
Also, I don't get how the white mechanism is affecting the state of the ball below and thus open/closing the valve. It looks like it pushes down on the ball. But when I try to do that manually, nothing happens.
Anyone else have this model of diverter valve that can provide some insight into the problem?
