Why Choose the New Water 400 Series?

Standard chlorine feeders can be messy and imprecise, leading to over-chlorination or algae blooms. The New Water 400 Series removes the guesswork. Its Erosion Technology wets only the bottom of the chlorine pac, delivering a more consistent residual than traditional "soak and float" methods. It is the ultimate upgrade for pool owners who want professional-grade water quality with residential ease of use.

Perfect for:
🏊 In-Ground Pools: The robust choice for larger water volumes (up to 40k gal).
🛑 Safety First: No handling of raw chemical tablets or breathing in fumes.
⚙️ System Protection: Prevents corrosion of expensive pool heaters and pumps.

Compatibility & Required Refills:

Ensure you have the correct setup for this model:
🔹 Required Refill: Uses the larger New Water Series 400 (Model 407C) 7lb Pacs.
🔹 Plumbing: Installs in-line with standard hard PVC plumbing.
🔹 Wrong Pool Type? If you have an Above Ground Pool (up to 25k gal), you need the smaller New Water 120 In-Line Chemical Cycler.
