I haven't had a chance yet to try it but I think that the moving of the joystick will work. Last night after seeing the replies I recall the RK person telling me that you have to use the curl/dump function when I bought the kit months and months ago but I forgot about it. I guess they don't expect anyone to buy the kit and install it themselves because it comes with no instructions other than a photo of the plumbing of the new hoses. Nothing about the operation of the valve.
LD1, why did you feel you had to berate my neighbor who was willing to install that for me just because he said he had never installed a third function valve with only one button? The TYM label on the kit calls it a third function valve even though it's a diverter valve. I thought that this was a place for us to ask questions not get cut down.
