Re: Reconfiguriing a Jandy 3 way valve
You should not have to reposition anything, just take out the stops that only allow the valve to turn 180 degrees. The valve is "open" in the direction that the handle points (there is usually the word "off" opposite the handle). Once you have 360 degree rotation of the valve just point the handle away from the center port of the valve (and "off is pointed at the center port if you have that placard installed on your valve).
