Pure, clean, healthy water for your home is essential

Water filters have become increasingly common in our houses and offices. What many people might not realise, however, is that water filters need to be installed by a licensed plumber. Installing a water filter is not a do-it-yourself plumbing job. A DIY install can result in a fine of up to $10,000.

Because it is considered sanitary plumbing, a water filter has to be installed by an authorised plumber. This includes water filters for the whole house as well as single filter units installed under the kitchen sink. Exceptions to this are filters that have a push-on connection fitted to the outlet of a kitchen tap, such as a rubber push-on connector, or stand-alone tank/bottle type filters.

Potable, safe water at the turn of a tap

We offer new installations of filter systems for tank water, town water or kitchen under-bench units. Many brands are on the market, but we recommend you always look for NFS certified water filters.

How UV water filters work

UV water filters sterilise water from rainwater tanks of houses, baches, farms and lifestyle blocks.

They are an environmentally friendly solution for dealing to unwanted guests in your water and making it safe to drink. UV filters kill 99.99% of all microorganisms, such as algae, protozoa, bacteria and viruses without adding chemicals like chlorine.

FlowFix Plumbing can ensure you enjoy safe and healthy water from every tap in the house.

UV water filters for tank water

Rainwater is safe to drink as long as care is taken. Drinking unfiltered rainwater will expose you to increased levels of bacteria, germs and viruses.

If you live rurally in Rodney or the Hibiscus Coast, there’ll be a pretty good chance you rely on a rainwater tank for your household water. There is also a pretty good chance your water tank contains lead, pesticides, nitrate, giardia, campylobacter, e-coli, Cryptosporidium and salmonella causing organisms.

Rainwater gets contaminated by dust, sprays, chemicals, leaves, faecal deposits from birds, frogs, rodents and possums, pollen, moss, lichens, moulds and dead animals and insects. These form a thick layer of sludge on the bottom of your tank and a breeding ground for potentially harmful bacteria that can make people extremely unwell.

Massey University undertook a 5-year study in which at least half of samples the roof-collected rainwater from New Zealand homes were not up to the minimum acceptable standards. 30 per cent showed evidence of heavy faecal contamination.

Popular types of water filters for household use

We supply a wide range of home water filtration systems: above-the-bench, under-bench models, and whole-house filters. We also supply replacement filter cartridges and UV tubes. These should be replaced every 12 months.

Protect your home and family

A UV water filter alters the cell nucleus and makes cell division impossible. This makes water potable and safe to drink. At FlowFix, we recommend a trusted brand like Viqua. A number of UV lamps have a reputation for giving electric shocks when you take them. They also don’t last the full 12 months. We have never had any of those issues with Viqua UV filters.

Why put water filters on town supply water?

Town water is already treated, sanitised and safe to drink. So why would urban homes need water filters? The two most common reasons are taste and allergies. Thanks to chemicals like chlorine or metals like aluminium, treatment can alter water taste significantly, 

Town water comes into homes in New Zealand via a system of metal water pipes. Due to their strength and durability, councils do not regularly replace these water pipes. Some old pipes contain lead, rust and even asbestos which affects both the taste and the water quality. Allergies to various chemicals and metals are relatively common which is why many people recommend filtering town supply water.
