Help me double-check my replacement equipment.

I bought a house in the fall with an old, in-ground pool. It is probably 30+ years old and in need of all new equipment and eventually cosmetic things as well. My goal is to replace all the equipment (heater, filter, pump - 100% of it) in the next few months, then over the next few years save up for and do the necessary big ticket items like replaster, and repour the pool deck.

The pool is a 20x40 w/ step, I calculate ~32,000 gallons at avg depth of 6ft (3 at shallow end, 9 at deep end). There are 3 supply jets, 2 skimmers, and 1 main drain. All piping is combined somewhere under the pool deck, and there is only a 2" PVC and 1.5" PVC coming to and from the pool.

I am looking at the following equipment:
Pump: Pentair Intelliflo3 3HP w/I/O 0011076
Heater: Raypak Avia 399k BTU natural gas Nitek 018045_A
Salt System: Circupool RJ60 Plus
Filter: VEVOR Cartridge 425sf

I mostly want to know if the above primary components are all compatible and decent (i know the filter is a no-name, but the others are higher quality/cost, and a filter is a filter...). I believe flow rates are all compatible, and the nitek version of the raypak should be longer lasting than the copper HX.

I am seeking unsolicited advice from anyone with much more experience than me.

One other topic - I am relocating this equipment as part of this replacement, and am interested in what else to plan to include in my equipment pad/shed. Right now ill have:
1. a dedicated 240v circuit for the pump
2. a 120v circuit for the heater/salt system/wifi/whatever else
3. a gas supply line for the heater
4. a hose bib water supply
5. a nearby drain connected to my french drain/stormwater system
 
Welcome to TFP!!!

Those are all just fine. If you are good maintaining your water, the nitek isn't necessary. Plain copper works just fine.

1. a dedicated 240v circuit for the pump
Great
2. a 120v circuit for the heater/salt system/wifi/whatever else
Check the capacity of the circuit with all your equipment...but should be fine.
3. a gas supply line for the heater
You need to make sure the meter can handle the total flow of the house. You also need to ensure the piping is sized correctly. Need a knowledgeable plumber/HVAC to size it. 400K heaters typically need a larger meter and piping than a normal house has...
4. a hose bib water supply
5. a nearby drain connected to my french drain/stormwater system

Make sure you have a way to ensure the SWG is off if the pump is not running. You can get a Pentair IntelliFlo3 VSF Optional Universal Relay Control Board Kit 356365Z for that pump and turn the cell on and off...or you can roll your own.

Put a bypass on the heater:

Since you’re going to have to run the intelliflo with 240, setup the heater and salt cell to run on 240 as well. They will draw less amperage running 240 vs 120.

Do you have a light in the pool? I’m assuming you’re going to wire the IO board to control the heater and SWG?
Yes there is an old light in the pool - its 12V, and I know nothing about it. except the pool contractor who came out to quote me on plaster said it was real old, and with a copper conduit, if it goes out he thought it would not be possible to replace.

For now, I wanted to connect the IO board to the heater and SWG yes. I believe between the pump and the heater built-in automation, I may be able to avoid a full blown automation system for $2k or more.

Instead of spending money to avoid that full blown automation system, use it to put in a full featured system.

You are not going to save yourself much by building a mutt of pool equipment from different manufacturers.

You need an electrical subpanel that comes with the IntelliCenter. Forget the IO Board and get a MasterTemp heater and IntelliChlor Plus SWG.

You will have better equipment, that is easier to operate, and maintain.

You are buying enough Pentair equipment that you should ensure you qualify for their 3 year warranty bundle.

That is interesting - although it looks like the warranty would require me having a certified installer do it (my hope was to install myself - i do plumbing and hvac and electrical, so while i havent done pool equipment, im familiar with all the materials and concepts).

It might come down to paying ~5-10K to an installer over the material cost for just the warranty.

Pentair's definition is broad...

*Professional Installation – Defined as product installation by a qualified professional who charges a fee for their services, and possesses a business license, and/or contractor's license. Common examples of a “qualified professional” include: Swimming Pool, Home Repair or Landscape Professional; Plumber or Electrician; General Contractor; Heating and Air Conditioning Specialist.

You can prep much of the work and they can inspect it and do the final connections. You just need to get an invoice from them for "Installation" to present to Pentair when you register the warranty.

You have friends who meet that definition?

Unfortunately I don't have a contractor friend but I wouldn't mind paying one of the pool companies that came out and gave me initial quotes to achieve this.

On your recommendation I went down a Pentair rabbithole and would love if you (or anyone else reading) could doublecheck my new equipment list:
1. $3,700 - Pentair MasterTemp Pool Heater 400,000 BTU Natural Gas HD 460805
2. $1,649 - Pentair IntelliFlo3 VSF Variable Speed & Flow Pool Pump | 3HP 208-230V 2590W | 011075
3. $1,459 - Pentair CCP420 Clean & Clear Plus Cartridge Filter EC-160301 | 420 sq.ft.
Lastly - It looks like if you buy a bundle, you can get the Intellicenter WITH the salt system:
4. $2,799 - Pentair IntelliCenter System Load Center | i5P Personality Kit and IC40 salt cell | 521905 | Single Body

Shipping: $200
Total Pretax: $9,802

My other option is to buy the automation panel and SWG separately - not sure which is the way to go, but this is definitely cheaper.

Lastly, are these decent prices? in looking around, it looks like www.poolsupply4less.com seems to have the best pricing.
