I have an 18 X 47 lazy L vinyl liner pool being installed now. I plan to order 2 pentair 12v LED lights and am trying to decide how long to order my whips. One will be short but the other I can't decide on how best to run the wiring. I have two niches installed on opposite sides of the pool more or less diagnonally opposite of each other. My question is at this point my installer just has 3/4" pvc "stubbed up" at each niche he recommended a junction box at each site which will be flush in my pool surround/concrete. Would it be preferable to run 1" pvc on the "long run" for the light that is on the opposite side of where my control/switch will be and keep the bends as large a radius as possible to facilitate pulling the whip thru them when the need arises. Also can I "home run" both conduits to the control box which is about 25' from the pool and avoid the junction boxes being in my slab/concrete surround. If so is it a problem pulling the whip all the way around a pool thru 1" pvc? Does using silicon lubricant take care of friction/sticking issues?
Thanks for your help!
