We bought our house (with pool!) in Orange County, CA in 1977 and we still own it. The pool was installed by a previous owner in 1975. We did a major remodel in 2012 (installed dual drains in pool and spa, pebbletec surface, saltwater, all new Pentair equipment, new decks, Zodiac MX80, etc.). I do all my own maintenance and repair. Replaced temperature sensors, rebuilt the Zodiac (twice), and recently used a reverse osmosis service to recondition the water to better-than-tap chemistry. I installed a Pentair Intelliph (acid dispenser) four years ago, and am currently working to replace a failed controller board with some home-brew electronics (see this Arduino Post ). Yeah, I'm an engineer and life-long tinkerer--it's a sickness.
