UV Water Filter Service Dairy Flat & Coatesville

Safe, E. coli-free tank water for homes and lifestyle blocks from Dairy Flat, Coatesville and Riverhead to Albany Heights.

Protect your drinking water with UV water filter servicing in Dairy Flat and Coatesville

Dairy Flat and Coatesville are only minutes from Albany, but most properties here still get their water from rainwater tanks or private bores. That makes your UV system the final barrier between your tank and your family.

Every annual service includes a new UV lamp, a clean of the quartz sleeve, a full check and replacement of your filters, and a check and reset of the controller. We then sterilise the water lines into your home, following the manufacturer’s recommendations.

Why UV water treatment matters on lifestyle blocks

Lifestyle blocks around Dairy Flat, Coatesville and Albany Heights often have big roofs, sheds and stables feeding the tank. Birds, possums, leaves and dust on those roofs can wash bacteria such as E. coli into your water with every shower of rain.

A well-maintained UV system kills those bacteria before the water reaches your taps, without chemicals and without changing the taste of your water.

Professional UV Water Filter Service for Dairy Flat & Coatesville
Safe, reliable protection for your drinking water

UV-Filter-Service

Is your UV system still protecting your water?

You can’t tell by looking. A UV lamp keeps glowing for years, but its disinfecting strength drops off after about 12 months, and minerals and fine sediment build up on the quartz sleeve and block the light.

On lifestyle blocks with large roofs and sheds, the pre-filter can also clog faster. Once that happens, bacteria can get past the UV and into your home.

An annual service puts all of that right, so you know the water from every tap is safe to drink.

FAQ about UV Water Filter Service in Dairy Flat and Coatesville

Do homes in Dairy Flat and Coatesville need UV treatment?

Almost every property in Dairy Flat, Coatesville, Riverhead and Paremoremo is on its own rainwater tank or bore. Parts of Albany Heights now have mains water, but most homes there are still on rainwater. Tank and bore water isn’t treated before it reaches you, so we recommend UV on every supply that’s used for drinking.

Fitted after a sediment filter, a UV system kills bacteria such as E. coli before the water reaches your taps. It’s the final barrier in a whole-house water treatment system.

How often should a UV system in Dairy Flat be serviced?

Every 12 months. A UV lamp keeps glowing long after it stops producing enough UV light to kill bacteria, so you can’t tell by looking at it.

When we service your system, we add you to our annual reminder list, so you’ll hear from us when your next service is due.

We rent out a property on tank water. What should we be doing?

As a landlord, you’re responsible for giving your tenants a safe, working water supply. An annual UV service, with a record of each visit, is an easy way to show it’s being looked after.

We already look after rental properties around Coatesville and Dairy Flat for several property managers, and we can arrange access with your tenants or property manager.

Our lifestyle block has a big shed roof feeding the tank. Is that a problem?

It can be. Sheds, stables and barns often have birds roosting in or on them, and their droppings wash straight into the gutters. Large roofs also collect more leaves and dust.

Gutter guards, a first-flush diverter and a clean pre-filter all help, and the UV system deals with the bacteria that get through. We can check the whole setup when we service your UV.

Which areas around Dairy Flat do you cover?

We service UV systems in Dairy Flat, Coatesville, Riverhead, Paremoremo, Albany Heights, Lucas Heights, Redvale, Okura and Wainui.

This is the southern end of our service area, which runs from Mangawhai to Albany. One of our service technicians lives locally, so we can respond quickly when you need us.

Can you test our water for bacteria?

Yes. We offer laboratory testing for E. coli, total coliforms and other contaminants, and we can take the sample during your UV service. Call the office on 0800 278 296 to book a test.

What should we do if the UV alarm goes off?

Take it seriously. The alarm usually means the lamp is at the end of its life or the system has a fault, so your water may not be disinfected. Boil your water for drinking and cooking until it’s fixed.

Call us on 0800 278 296. Our vans carry UV lamps, quartz sleeves and controllers, so most faults are fixed on the first visit.
