The full picture
CircuPool has built a devoted following among DIY pool owners, and the RJ45+ is why: a robust titanium cell rated to 45,000 gallons, a 7-year manufacturer warranty that most competitors can't touch, and — crucially — no penalty for installing it yourself. It works with any brand of pump and filter on 120 or 240V. You give up the automation-ecosystem integration of Hayward/Pentair and the every-corner service network, but on the metrics that actually cost you money over a decade — cell longevity and warranty — it's arguably the smartest buy here.

The in-depth review
CircuPool earned its enthusiast following by winning on the numbers that actually cost you money over a decade, and the RJ45+ is the clearest example.
Where it wins
The headline is a 7-year manufacturer warranty — most rivals offer one to three — backing a robust titanium cell rated to 45,000 gallons. Because the cell is the expensive wear part, that warranty can save you an entire replacement over the system's life, often more than the price gap at purchase. It runs on 120 or 240V with any brand of pump and filter, and CircuPool explicitly doesn't penalize you for installing it yourself.
What you give up
You don't get Hayward/Pentair automation integration, and CircuPool is an online-direct brand, so there's no nationwide service counter — support is mostly with the manufacturer. For owners who want app-linked equipment or local hands-on service, that's the tradeoff.

Frequently asked questions
Does installing it myself void the warranty?
No — CircuPool explicitly allows DIY installation without a warranty penalty, which is a big reason handy owners choose it over brands that require professional install for full coverage.
How does a 7-year warranty change the math?
A lot. Since the cell is the expensive wear part, a 7-year warranty versus 1–3 years elsewhere can save you a full replacement cell over the life of the system — often more than the price difference at purchase.
Will it work with my Hayward or Pentair pump?
Yes — CircuPool systems are brand-agnostic and run on 120 or 240V, so they drop onto virtually any equipment pad. You just won’t get app integration with a Hayward/Pentair automation controller.
Is CircuPool a reliable brand?
It’s an online-direct brand with a strong owner following and long warranties. The tradeoff versus Hayward/Pentair is a smaller local service footprint — most support is direct with the manufacturer.
What size pool does the RJ45+ handle?
Up to 45,000 gallons, so it has generous headroom for most residential in-ground pools — which also helps the cell run gently and last longer.
Is it self-cleaning?
Yes — it uses reverse-polarity cycling to limit calcium scale on the cell plates, which helps maintain output and extend cell life.
