Full-house UV-C LED protection with Pearl Aqua Deca

This beast looks after every tap in the house — kitchen, shower, even the outside hose if you want. With its NSF-certified UV-C LED tech, it wipes out 99.99% of the nasties in your rain, bore, or mains water. It’s like having a personal water bodyguard that never takes a day off.

No mercury, no chemicals, no worries with this first UV-C LED point of entry residential system

Forget the old-school glass tubes and chemical treatments — this system’s all LED, all clean. No toxic bits to deal with and no funny tastes in your cuppa. Just pure, fresh water that’s safe for your whānau and good for the planet.

Low maintenance, high reliability

You won’t be mucking around changing bulbs or calling the plumber every year. Those solid-state LEDs run for yonks, and the system basically looks after itself. Aqua Works can give it a quick once-over during your regular service, and you’re good as gold.

Smart and efficient UV water filtration technology

The Deca 24C4’s got brains as well as brawn — it only switches on when water’s running, and it adjusts power automatically to save energy. Perfect for those off-grid setups around Warkworth, Matakana, or up the coast.

Cons of AquiSense Pearl Aqua Deca 24C4 UV Water Purification System

Yeah, it’s not cheap – UV water treatment with AquiSense

No getting around it — LED UV tech costs more up front than the old mercury-tube units. But you’re paying for the good stuff here: longer life, lower running costs, and future-proof gear. Think of it as a one-off investment in never having to worry about your water again.

Needs clear water to do its job – Pre-Filtration

If your rainwater tank’s a bit on the murky side, don’t skip the prefilter. UV only works if it can “see” through the water. Chuck in a Maelstrom or sediment filter and you’ll be sweet. Aqua Works can set it up properly so everything runs like clockwork.

Get the pros to install it

This isn’t a weekend DIY project, mate. You’ll want the crew at Aqua Works to handle the install — they’ll make sure your flow rate, plumbing, and pressure are spot-on. That way, your NSF certification stays valid and your system performs exactly as promised.
