We just bought a house with a pool in October (first pool!!), and I've been researching new pool equipment since December. This site has proven to be an invaluable tool! I found posts similar to the one I'm writing to be helpful so I'll add my two cents. After getting 3 quotes I decided on the company to replace everything. What's currently there:
Pentair Whisperflo 1HP pump
Polaris 3/4 HP pump
Pentair FNS Plus 60sq ft DE filter
An ancient Purex Triton 350M
Colorsplash 2G LED light
Pentair intelliflo VS 3hp
Pentair intellichlor IC40 (w/sacrificial anode)
Jandy Aqualink RS (IQ904-PS)
Rheem 336/406 Cupronickel heater (they need to look at my gas line to see what it can handle)
They will also be re-plumbing a few things, because there are several unnecessary turns.
Two out of the three companies suggested getting the superflo instead of intelliflo, but ultimately I decided on the intelliflo because of the greater electrical savings it should provide, the quieter operation (due to it being able to run at a lower RPM for the same task), and the lack of information I could find about the superflo pump.
I went with the Rheem heater not only due to the installer's recommendation, but also because of the glowing reviews from other members of this site.
It was a no-brainer choosing the intellichlor, it seems to be the best out there.
It was a little more difficult choosing the automation system, but I ultimately decided on the Jandy because it seems to offer the most flexibility at a reasonable price, compared to the intellitouch system.
Other things I bought- the Taylor TF-100 test kit w/ magnetic stirrer, a Dolphin Nautilus Plus, a fountain that attaches to the pressure line, and of course a ton of pool games and toys.
Can you tell I'm ready for Spring?!
