I have an older pool and have a problem with excess waterloss (probably combination of above normal waterline (but below overflow of attached spa) leaks and the dry desert air (which takes a real toll on overflow splash water!)

I'd LIKE to reconfigure my Jandy Valve actuator on the return to be just about 15 degrees off..Basically give a LITTLE flow to the spa (so that the little hole in the overflow wall can handle the flow, yet continue to provide water turnover) and the rest to the spa....

I can't figure out a way to reconfigure the Jandy Actuator to do this..I assume it isn't possible, but wanted to see if anyone had any ideas....
