I've gotten a few questions about my equipment upgrade DIY project, so I thought I'd lay out the major pieces here. This is what we moved in to...

2" plumbing with a 1.5" multiport valve; one vintage Jandy valve and two newer Neverlubes; a vintage Anthony brass single speed pump; Pentair FNS Plus DE filter; the world's loudest spa blower; two vintage Intermech timers (only 1 in working order); and a sketchy subpanel mounted on a 2x6 board stuck in the ground. Weeds all over. And note the old propane regulator just sitting there with no heater. 300 gal tank 1/4 filled still sitting in the back yard that hadn't been used in decades.
Phase 1 - add a Raypak 336A natural gas heater. Had the line run from the street, heater ordered and installed. Also, replaced the blower with a new and quieter Pentair. Now, at least we have a hot tub... not just a tub.
Phase 2 - electric bills were high, so swapped out the Anthony relic for a Pentair Intelliflo VS pump. Replaced the lattice on the enclosure and did some weeding. Also, got a Doheny's Discovery (Dolphin) robot cleaner. Better, but still nowhere near what I wanted.

I got estimates to upgrade to an automation system, re-do the plumbing and even relocate the pad - we hate having it right between the house and the pool. Best set of bids came to over $14k. Even without moving the stuff.
So, I spent the winter shopping for deals and planning the job.

- Tear everything out and re-do the pad area. We chose field stone pavers.
- Order Pentair Intellitouch load center, new breakers, personality kit, screenlogic2, multi-color LED pool and spa lights, new valves, actuators, Intellichlor IC-60 SWG, 2" hi-flow multiport valve, and some new outlets to control landscape lighting and such.
