Hey Cory, I'm in the final stages of putting mine in. Never done PVC work and not too much wiring beyond fans/lights etc. I paid $830 for my Goldline Aquarite and controller. Add to that about 70 for salt, CYA, pvc, sweep 90 degree elbows, PVC cutter (cause I can't use a hack saw and cut straight to save my life), power wires and conduit (doesn't come with it). I couldn't finish tonight because the grounding terminal board in my breaker box was corroded beyond use. Couldn't get a wire on to it.
Couple of things you might want to consider:
Your current plumbing situation will dictate how easy or difficult that's going to be. Mine was pretty straight forward. In doing my research (wandering between people's houses) I saw some real nightmares. You can mount the cell vertically or horizontally (I did mine horizontal), but the controller box has to be mounted upright. Make sure you get 12" of straight run pipe prior to (upstream) the flow switch. The cell can count as that 12 inches. The manual has some pretty good diagrams of possible plumbing options.
You can get your PVC pipe from the big box stores, but go to the pool store and get your unions and sweep 90's. Pool joints have significantly deeper female ends on them for the extra gluing surface you need to withstand the pump pressure. There are some really good youtube videos on gluing PVC.
I've taken mine very slowly. 1) Dumped in the salt one after noon and swept to dissolve. Drank beer. 2) Mounted controller on wall next day. Beer. 3) Did plumbing in a couple of hours. Measure, measure, measure, or your job will end up looking like something out of a Dr. Suess book. Have a sharpie to help mark your joints. Cut and fit everything first, THEN glue. I used toothpaste to get everything to slide together and hold. Rinsed it all off and let pipe/fittings dry. Glued it and let it all cure over night. More beer. Then tonight I commenced to wiring. NO BEER!!
I'll finish up tomorrow and let you know how mine turns out.
Peace, Jim
