Hi TFP folks! I've been lurking for awhile and really appreciate what a great resource this forum is. I was already convinced that SWG was the right choice for us thanks to many detailed posts on that subject.

We're just about to embark on a new pool project here in Austin, Texas. I thought I'd post the specs and design plans to see if anybody has any feedback or recommendations before we sign the contract. Though I grew up with a pool, this would be my first time owning and maintaining one, so I have lots to learn! I'm especially interested in any feedback on construction or equipment options, questions we should ask, etc.

Thanks in advance! I plan to share a lot more as the process continues.

welcome to TFP. You have found a great resource to help in your pool construction and maintenance.
Your pool volume is estimated around 20,000 gals. Your PB is using all Jandy equipment so get the AquaPure 1400 which is rated at 40,000 gals. It is the largest SWCG that Jandy offers.

The design is unique with a double Baja shelf.
Are you getting the pool cover due to a lot of trees around your pool or is it mainly for safety reasons? Just curious.

Get the specifics on the Automation systems as Jandy has several models with varying degrees of capability. You can go to their website for more info.
The large cartridge filter is great. As is the 400BTU heater. You may want more specifics on the VS pump as Jandy has several models. But all are good.

120 days after excavation is a short timeline in this age of excessive demand for pools. I do hope the PB can stand behind that.
Good Luck And keep us posted.

Yes, we have about a dozen oak trees surrounding the pool area. They dump leaves and pollen a couple times a year and we figured the cover would help the pool stay much cleaner. We also back up to open space so the cover should help keep out lots of critters that might otherwise drown in the pool. The safety aspect will be a relief for future kids as well.

Just heard back on the SWCG, and it looks like it will be the AquaPure 1400 (we were sent the manual for the 700 and 1400, and the 700 is only for 12k gal). I asked them to make that explicit in the contract, thank you!

I’ll ask for specifics on the automation and pump systems.

The design is unique with a double Baja shelf.
Yeah, we iterated on designs with a bunch of builders but ultimately landed here. It gives us plenty of tanning ledge space, nice symmetry, and the deep end shelf will act as a bench for the deep end and hopefully make it feel less lonely down there 🙂 Since the whole thing is a rectangle the single cover will slide over the entire area too.

What would you say is a realistic timeline these days? 120 working days is 6 months after the dig, which we thought was realistic. Fortunately our builder purchased lots of extra equipment when the shortages started hitting so they have garages filled with enough pumps & parts to keep their projects moving.

Hi, welcome to forum! Nice build. My dig started in late May and the builder is confident we'll be swimming in September. 6 months is possible right now. Roadblocks my builder navigated well but still had delays: couldn't find 2.5" PVC pipe, scheduling challenges with excavator but more so with the gunite crew. I sat for about 1 month with steel and pluming in the hole before the gunite was shot. The rest of my project here on out is fullly in their control, outside of Pentair sending us the equipment :).

I got the info back on the automation system and pump:

Automation System: POL-30-9204 - IQ904-PS AQUALINK RS4 POOL

Variable Speed Pump: TLD-10-1001 - VSPHP270DV2A 2.7THP 115/230V

Any thoughts or recommendations on these?

This is the base system and includes 2 controllers for 2 valves (1 on return and 1 on suction). This allows automation to go from Pool Mode to Spa Mode and back to Pool Mode.
it has 4 relays to allow control of the SWCG, pool light and spa light. Just need to verify that is all you need to control.
It has wireless to connect to your phone, computer.

see the attached brochure that shows all the various features - your is the RS-PS4

That should be sufficient for what we need to control initially, though I might want to make it easy to expand with a chiller in the future—I guess we’d need more relays for that?

One thing I’ve seen in a few threads are various recommendations about PVC sizes. Do the sizes above (2.5” main drain, 2” skimmers + returns) sound ok, or should I be pushing them to use 2.5” for everything?

This should be fine. The PB should run some basic calculations based on length of runs and elevation of pool to equipment pad. Many pools use 1.5" returns and only 2" suction. So having 2" throughout with 2.5" suction on main drain should be sufficient.

How many jets for your spa - and is it requiring an extra pump? We are thinking of a 10x10 and getting mixed answers from builders based on our request for 16 jets. Some are saying we need a second pump and others say one is fine.

As of now the plan is four jets using the same single pump. Debating whether we should add more, because it is a good size spa.

Took awhile, but we've signed the contract! A few updates since my last post:
  • The number of spa jets was incorrect on the original contract, we're actually getting 10 which makes sense for the large spa.
  • We're using 2.5" PVC everywhere (I saw this recommended elsewhere).
  • We added an auto-fill system along with associated plumbing to ensure that we don't need to pull a hose over to the pool on a regular basis.
  • Construction timeline is estimated at 90-120 working days, plus weather delays. With any luck this puts us at a timeframe of April for completion of construction.
I'll keep this thread updated as we go through permitting and final design!
