Watersprint · UVC LED water disinfection
Whole-house UV disinfection, without the lamp
Mercury-free UVC LEDs that reach full output the moment water flows. No warm-up, no glass lamp, no yearly lamp change.
Rein Water USA is an authorized Watersprint dealer.
Why UVC LED
A new light source for UV disinfection
Conventional UV systems use a mercury lamp inside a glass tube. Watersprint replaces the lamp with UVC LEDs.
| Watersprint UVC LED | Conventional UV lamp | |
|---|---|---|
| Light source | Mercury-free LEDs | Mercury lamp |
| Glass | No glass tube | Fragile, bulky glass tube |
| Start | Full output instantly | Warm-up time |
| Replacement | Core: about every 5 to 7 years for a household of four | Yearly lamp replacement |
| Size | Compact. Core is 11″ tall | Larger system |
- Low standby power. Core uses less than 1 W when no water is flowing.
- No heat transfer to the water. The light source is off when no water is flowing.
- Simple handling. The LEDs contain no mercury, during use and at disposal.
How it works
On when water flows. Standby when it stops.
The system installs at the point where water enters your home, so every outlet is supplied with disinfected water.
-
The flow sensor
An external flow sensor detects water flow. The control unit switches the UVC LEDs on automatically.
-
Instant UVC light
The LEDs give full output at once, so water is disinfected from the moment it begins to flow.
-
Hygienic Pulsing
On Watersprint Core, Hygienic Pulsing activates the system automatically during periods of inactivity. The rest of the time it rests in standby.

Is it right for my water?
UVC light needs clear water
Incoming water quality decides how well UVC disinfection performs. These are the recommended levels for Watersprint Core. Pre-filtration may be needed, depending on your water.
| Parameter | Recommended level |
|---|---|
| UV transmittance (UVT) | Above 95% |
| Turbidity | Below 0.3 NTU |
| Hardness | Below 8.3 gpg |
| Iron | Below 0.3 ppm |
| Manganese | Below 0.05 ppm |
| Tannins | Below 0.1 ppm |
| Color | Below 10 mg/L Pt |
| Maximum particle size | Below 20 microns |

Questions
Frequently asked questions
How is UVC LED different from a conventional UV lamp?
A conventional UV system uses a mercury lamp inside a glass tube. Watersprint uses mercury-free UVC LEDs. There is no glass tube, the LEDs give full output instantly with no warm-up time, and the system rests in standby when no water is flowing.
How long do the UVC LEDs last?
Watersprint Core has a replaceable UVC LED unit with a replacement interval of 3,000 active hours, about 5 to 7 years of normal use for a household of four. The Acuva ArrowMAX Home 10K has fixed UVC LEDs with a lifespan of 10,000 active hours.
Which model fits my home?
Watersprint Core 20 is for flow rates up to 8 gpm and Core 40 for flow rates up to 16 gpm. The Acuva ArrowMAX Home 10K delivers 10.6 gpm at 16 mJ/cm² and adds a display and app monitoring. Send us your water source and peak flow and we will help you choose.
Do I need pre-filtration?
It depends on your water. UVC disinfection needs clear water, with UV transmittance above 95%, turbidity below 0.3 NTU, iron below 0.3 ppm and hardness below 8.3 gpg for Watersprint Core. Pre-filtration may be needed. Our Free Water Match looks at your water and tells you what it needs. Start your Free Water Match.
