Water Filter System Wellington:
Clean, Safe Water for Your Home

Clean, Safe, Great-Tasting Water for Your Home or Business

Access to clean, healthy water is essential for every Wellington household. Over time, local supply lines can introduce sediment, chlorine, rust, micro-plastics, chemical residues, and unpleasant tastes or odours into your drinking water. A professionally installed water filter removes these contaminants and gives you consistently clear, great-tasting water straight from the tap.

Southern Plumbing & Gasfitting Ltd installs, replaces, and services a full range of water filtration systems across Wellington. Whether you need a simple under-bench filter for daily drinking water, or a whole-house system to protect appliances and improve water quality everywhere in your home, we supply and fit solutions built for Wellington’s water conditions.

Why Install a Filter in Wellington?

✔ Improve Water Taste and Odour

Chlorine and naturally occurring minerals can leave a metallic or chemical taste. A filter instantly improves the flavour and smell of your water.

✔ Remove Sediment and Rust

Old galvanised pipes and council mains sometimes release fine sediments. Filters prevent these particles entering your taps, fixtures, and appliances.

✔ Reduce Household Health Concerns

Proper filtration reduces contaminants such as:

• Chlorine and chloramines

• Lead and heavy metals

• Microplastics

• Sand and silt

• Organic compounds

• Bacteria (with UV systems)

Compact and efficient. Ideal for kitchens where you want clean drinking and cooking water straight from the tap.

Whole-House Filtration Systems

A whole house filter system is the most comprehensive solution for improving the water quality throughout your entire home. Instead of filtering water at a single tap, a whole house system treats every drop as it enters your property. This means cleaner water for drinking, bathing, cooking, laundry, cleaning, and for protecting valuable appliances such as dishwashers, washing machines, hot water cylinders, and tapware.

In Wellington, whole house systems are particularly beneficial because older supply lines, ageing council mains, and varying water conditions can introduce sediment, rust flakes, chlorine, and other impurities into your household plumbing. These contaminants not only affect taste but can also cause scale buildup, staining, corrosion, and premature wear on fixtures and appliances. A professionally installed whole house system provides consistent water clarity and protects the long-term health of your plumbing.

Sediment – Carbon Filter – UV Unit

The system usually begins with a sediment pre-filter, capturing sand, silt, rust, and fine debris. This prevents blockages and extends the life of downstream filters and appliances. The next stage often uses a carbon filter, which removes chlorine, chemical residues, odours, and unpleasant tastes. For households using rainwater, bore water, or rural supplies, an optional UV sterilisation unit can be added to neutralise bacteria and biological contaminants without chemicals, ensuring safe and clean water for every use.

Installing a whole house water filter is also a practical way to safeguard your hot water system. Sediment and mineral buildup inside cylinders and heat exchangers can reduce efficiency, shorten service life, and create maintenance issues. By filtering water before it reaches these appliances, you improve performance and reduce long-term running costs.

A well-designed system also benefits your daily comfort. Showering with filtered water helps reduce skin dryness and irritation caused by chlorine and other chemicals. Fixtures and glass showers stay cleaner for longer, with fewer mineral stains and scale deposits. Laundry comes out softer, brighter, and free from pipe residue.

Our technicians ensure correct flow rates, pressure compatibility, and high-quality filter media so your system performs efficiently at all times.
