Water Filtration Systems in Darwin
Cleaner, Better Tasting Water for Your Home or Business
Clean drinking water is something we rely on every day. While Darwin's mains water is treated to meet Australian drinking water standards, many homeowners and businesses choose to install water filtration systems to improve the taste, reduce chlorine, remove sediment and enjoy cleaner water straight from the tap.
At Apex Plumbing & Drainage Services, we supply and install a wide range of premium water filtration systems for homes, offices and commercial premises throughout Darwin and surrounding areas.
Whether you're looking for a simple filtered drinking water tap, a whole-house filtration system or a premium Zip HydroTap providing instant boiling, chilled and sparkling water, we can recommend and install the right solution for your needs.
Why Install a Water Filtration System?
Water filtration systems are designed to improve the quality of the water you use every day.
Depending on the filtration technology selected, a quality water filter can help reduce:
-
Chlorine taste and odour
-
Sediment and fine particles
-
Rust particles
-
Dirt and sand
-
Organic compounds
-
Some heavy metals
-
Certain bacteria and microorganisms (with appropriate filtration and UV systems)
-
Scale-causing minerals (with specialised treatment systems)
Many customers choose filtration because they simply prefer the taste of filtered water, while others want to protect appliances, improve water quality throughout the home or reduce the need for bottled water.
Water Quality & Everyday Comfort
Although chlorine plays an important role in disinfecting public drinking water supplies, some people notice its taste or smell more than others.
Many customers also report that reducing chlorine in their household water improves the feel of their water for:
-
Drinking
-
Tea and coffee
-
Cooking
-
Washing fruit and vegetables
-
Showering
-
Bathing
Some people with sensitive skin feel that highly chlorinated water can contribute to dryness or irritation, although experiences vary from person to person. Installing an appropriate filtration system can reduce chlorine levels where suitable filtration media are used.
Choosing the Right Water Filtration System
Every home and business has different water usage requirements.
We install a range of systems to suit different applications, including:
Under Sink Water Filters
Under sink filtration systems are one of the most popular options for residential homes.
Installed neatly inside your kitchen cupboard, these systems filter drinking water before it reaches either a dedicated filtered water tap or your existing mixer (where compatible).
Benefits include:
-
Hidden installation
-
Excellent drinking water quality
-
Cost-effective filtration
-
Reduced bottled water usage
-
Easy cartridge replacement
Perfect for families wanting filtered drinking water without modifying the entire home's plumbing.
Whole House Water Filtration
Whole house filtration systems treat the water entering your property before it reaches every tap, shower, toilet and appliance.
Benefits include filtered water throughout the entire home, including:
-
Kitchen taps
-
Bathroom basins
-
Showers
-
Baths
-
Laundry
-
Outdoor taps
-
Hot water systems
Whole house systems can help reduce sediment entering your plumbing while providing cleaner water throughout your property.
These systems are particularly popular for families wanting every outlet supplied with filtered water.
Filtered Water Taps
Dedicated filtered water taps provide fresh filtered drinking water from a separate tap installed beside your kitchen mixer or incorporated into selected multi-function mixers.
These systems provide:
-
Convenient filtered drinking water
-
Cleaner tasting water
-
Modern appearance
-
Reliable everyday performance
They are an excellent choice for homes wanting high-quality drinking water directly from the kitchen sink.
Commercial Water Filtration
Businesses often require larger filtration systems to protect equipment and provide high-quality drinking water for staff and customers.
We install filtration systems for:
-
Offices
-
Restaurants
-
Cafés
-
Hair salons
-
Medical clinics
-
Schools
-
Childcare centres
-
Commercial kitchens
-
Industrial workplaces
Commercial filtration systems can improve beverage quality while helping protect coffee machines, ice makers and other water-using equipment.
Understanding Filtration Levels
Not every water filter removes the same contaminants. The right system depends on your water quality, intended use and desired outcome.
Single Stage Filtration
Single-stage filters pass water through one filter cartridge.
These systems commonly reduce:
-
Sediment
-
Dirt
-
Rust particles
-
Chlorine taste and odour
Single-stage systems are affordable, compact and suitable for many homes wanting improved drinking water.
Triple Stage Filtration
Triple-stage systems provide more comprehensive filtration by adding an additional treatment stage.
Configurations vary but may include:
-
Sediment filtration
-
Carbon filtration
-
Fine micron filtration
-
Specialised contaminant reduction media
These systems are ideal where higher water quality is desired or incoming water contains greater levels of sediment.
Twin Stage Filtration
Twin-stage systems use two cartridges, allowing each stage to perform a different job.
Typically:
Stage One
-
Removes sediment, sand and larger particles.
Stage Two
-
Uses activated carbon or specialised media to reduce chlorine, taste and odour while improving water quality.
These systems generally provide a higher level of filtration than a single-stage unit and often extend cartridge life.
UV Water Sterilisation
Ultraviolet (UV) systems disinfect water by exposing it to ultraviolet light as it passes through the unit.
UV systems are commonly used alongside cartridge filters and can help inactivate bacteria, viruses and other microorganisms without adding chemicals to the water. They are especially useful where untreated rainwater or bore water is being used, or where an extra level of microbiological protection is desired.
Because UV light works best in clear water, pre-filtration is typically installed ahead of the UV chamber to remove sediment.
Water Filter Maintenance
Like any plumbing appliance, water filtration systems require routine maintenance to continue performing effectively.
The most important maintenance task is replacing the filter cartridges.
Over time, cartridges become clogged with the contaminants they have removed, reducing water flow and filtration performance.
Typical replacement intervals are:
-
Every 6–12 months for most domestic drinking water systems.
-
More frequently where water use is high or sediment levels are elevated.
-
UV lamps are generally replaced approximately every 12 months (even if they still illuminate), as their germicidal output decreases with time.
-
The correct interval depends on your water quality, filter type and household usage. We can recommend a maintenance schedule suited to your system and provide ongoing servicing, including cartridge and UV lamp replacement.
Regular servicing helps ensure your water continues to taste great and your filtration system performs as intended.
