Quick answer

Your Puretec UV needs a full service every 12 months to keep your water safe. Many are put in on new houses and then forgotten: no service plan, no instructions, and nobody booked to come back. UV servicing is one of our specialties, and we do it thoroughly, to Puretec’s own specifications.

  • A new Puretec lamp, timer reset
  • New filter cartridges
  • Quartz sleeve cleaned or replaced
  • Water lines sterilised
  • A reminder when the next one’s due
  • From Mangawhai to Albany

5 reasons to let us service your Puretec

A Puretec Hybrid is a good system, but it only protects your water if it’s serviced every year. Here’s why Puretec owners leave it to us.

  1. Someone has to look after it. Lots of Puretecs are put in on new houses. By the time you move in, there’s often no service plan and no manual, and the plumber who installed it has moved on to the next build. We’ll take it on, whoever installed it.
  2. Done to Puretec’s specifications. We fit the right Puretec lamp, sleeve and cartridges for your model, and follow Puretec’s own service steps, right through to the timer reset.
  3. We do the steps that get missed. A new lamp is only half the job. We take out the quartz sleeve and clean it, because a film on the glass blocks the UV light, and we sterilise your water lines afterwards, as the manufacturer recommends.
  4. Usually done in one visit. Our vans carry more than 50 UV lamps, quartz sleeves and controllers, so most services are finished in one visit. Old lamps are recycled properly.
  5. Reminded every year, and covered. We book your next reminder for 12 months’ time. Keep it serviced with us and the Aqua Works E. coli-free guarantee covers your rain or bore water (the conditions are on our UV water filter servicing page).

What our Puretec service includes

We service Puretec systems once a year, and every service covers the same steps:

  1. A new Puretec UV lamp, and the timer reset to 365 days.
  2. New filter cartridges to suit your model.
  3. The quartz sleeve taken out and cleaned, or replaced if it’s scratched or stained.
  4. The UV unit and your water lines sterilised, so no bacteria are left in the pipes.
  5. Seals, O-rings, power supply and surge protection checked.
  6. A check that your water flow suits the system.
  7. A reminder when the next service is due.

To book: call 0800 278 296, or email a photo of your Puretec and the label inside its lid to healthy@aquaworks.co.nz. We’ll confirm your model and send you a quote.

Why is my Puretec UV beeping?

Most of the time, the beeping means your yearly service is due. Every Puretec Hybrid has a controller that counts down the 365 days of lamp life. When it reaches zero, the alarm beeps and a red light flashes.

The lamp still glows, but after a year its UV output has dropped, so it may no longer treat your water properly.

The controller sits under the lid of the cabinet. Its display shows how many days the lamp has left.

Puretec alarms and fault codes

Display flashing There’s been a power cut Reset the controller
EC1 (Hybrid E) No lamp detected. Can’t be silenced Check the lamp is connected

How to silence the alarm and reset the timer

Hybrid G, R and HybridPlus

  1. To silence the alarm for 7 days, press and hold the silver button until “delay” shows on the screen.
  2. After fitting a new lamp, press and hold the silver button for 15 seconds, until “reset” shows. The timer goes back to 365 days.

Hybrid E series

  1. To silence the alarm for 7 days, hold the button for 5 to 15 seconds, until “DLAY” shows. You can only do this 4 times.
  2. After fitting a new lamp, hold the button for more than 15 seconds. The timer resets to 365.

Safety tip

Silencing the alarm doesn’t fix anything. Book a lamp change within the 7 days. If the light is off, or the controller shows EC1 or EC3, your water isn’t being treated: boil drinking water for one minute until it’s fixed, or call us on 0800 278 296.

Which parts does my Puretec take?

Open the lid and look for the label. It shows your model and the part numbers for the lamp, sleeve, cartridges and controller. If you send us a photo of it, we’ll bring the right parts.

Puretec lamps are in our online shop: the RL4, RL5, RL6 and RL7. For sleeves and cartridge kits, call us on 0800 278 296.

Can I service my Puretec myself?

You can if you’re handy, and Puretec’s own guides show you how. It’s more than a lamp swap, though. The two steps most often missed are cleaning the quartz sleeve and sterilising the water lines afterwards.

  1. Turn off the power and the water, and release the pressure.
  2. Change the filter cartridges.
  3. Take out the lamp, holding it by the ends, then remove and clean the quartz sleeve. Have a spare sleeve on hand: they’re fragile and hard to find in a hurry.
  4. Refit the sleeve and the new lamp, turn the water back on and check for leaks.
  5. Sterilise the UV unit and your water lines.
  6. Reset the lamp timer.

If you’d rather not, we’ll do it for you. Call 0800 278 296.

Safety tip

Never look at a lit UV lamp. UV-C light burns eyes and skin.

If a lamp breaks: it contains a small amount of mercury. Turn the power off, open up the space and leave it for 15 minutes, and keep children and pets away. Don’t vacuum. Wearing gloves, pick up the pieces with stiff card and sticky tape, and seal them in a jar.

Puretec UV FAQs

How often should a Puretec UV be serviced?

Once a year: a new lamp, new cartridges and a clean quartz sleeve. If your water is dirty, the cartridges may need changing every 6 months.

My Puretec came with the house. Can you service it?

Yes. We service Puretecs whoever installed them. Send a photo of the label inside the lid to healthy@aquaworks.co.nz, or call 0800 278 296, and we’ll confirm the parts and book you in.

Can I keep silencing the alarm?

Each silence lasts 7 days. On a Hybrid E you can only do it 4 times, then it shows EC4 and won’t silence again. The alarm is a reminder to replace the lamp, not a fault you can switch off.

Is my water safe while the alarm is going?

The lamp still works for a short time, but its output has dropped. Replace it within the week. If the light is off or the controller shows a fault code, boil drinking water for one minute until it’s fixed.

Which lamp does my Puretec take?

Check the label inside the lid. Hybrid G, R and HybridPlus models take the RL6, Hybrid E models take the RL7, older Hybrid H models take the RL5, and older R2700 and R5000 units take the RL4. All four are in our online shop.

Do you service other UV brands?

Yes. We service most UV systems used in New Zealand homes, including VIQUA, Davey, Bug Buster, Hallett and Aqua. See UV water filter servicing.

Where do you service Puretec systems?

From Mangawhai to Albany, including Warkworth, Matakana, Omaha, Snells Beach, Wellsford, Helensville, Orewa, Silverdale and Dairy Flat.

“Simply awesome. Steve is the best. I broke my tank water UV lamp quartz sleeve late on a Saturday. Classic mistake. These are difficult to find replacements for, even during the week. Was going to be without water for the weekend and was contemplating wife’s wrath and pricey bypass options. Steve not only answered the phone – unlike the first two numbers I tried – he quickly found me a replacement sleeve and met me half way (on his way out to dinner with friends) to deliver it. Beyond the call of duty. A definite life & wife saver!”
