Why Filter your Water
Better taste. Less sediment. Treatment suited to your water supply.
Whether you’re on town water, rainwater, a bore or a stream, the right system starts with understanding your water - and what you want to improve.
On town water?
Your water is already treated, but you may prefer a different taste or smell.
An appropriately selected carbon filter can reduce chlorine taste and odour. You can filter water at your kitchen tap for drinking and cooking, or choose a whole-house system.
Removing chlorine also removes its ongoing protection within your plumbing, so choosing, installing and maintaining the system correctly matters.
On rainwater, bore or stream water?
Clear water isn’t necessarily safe drinking water.
Contamination can enter through roof runoff, animal droppings, surface water or problems with tanks and bore seals. Some contaminants cannot be seen, tasted or smelled.
Filtration and UV disinfection work together to address different issues. Your water source and test results help determine whether additional treatment is needed.
Renting out a property on a private water supply?
Safe drinking water is part of providing a suitable rental home. If your property uses rainwater, bore or stream water, make sure the supply is properly maintained and the treatment suits its risks.
Filtration and UV disinfection can form an important part of that treatment. Water testing helps identify what your system needs and check that it is working effectively.
Check any requirements that apply to your property with your local council. If you have water-test results or a written treatment specification, send them through - we can help you choose suitable equipment.
What do filters and UV do?
Sediment filters capture particles such as sand, silt and rust. They also help prepare water for further treatment.
Carbon filters can improve taste and odour and reduce chlorine. Removal of other contaminants depends on the particular filter’s specifications. Ordinary carbon filters do not soften water or remove dissolved salt.
UV disinfection inactivates microorganisms. It needs sufficiently clear water, the correct UV dose and a flow rate within the unit’s specifications. UV does not remove sediment or dissolved chemicals.
Specialist treatment may be needed for hardness, iron, manganese, nitrate, arsenic or other dissolved contaminants. A standard sediment-and-carbon system is not a solution for everything.
When should you test your water?
For a private supply, testing helps you understand your source and check that treatment is working.
Arrange testing when:
-
You start using a new water source or move into a property with a private supply.
-
Taste, smell or appearance changes.
-
Flooding, repairs or changes around the source could have introduced contamination.
-
The supply has been unused for an extended period.
-
Routine testing is due under the programme recommended for your supply.
Ask an accredited drinking-water laboratory which tests suit your source and local risks. Microbiological testing and relevant chemical tests provide different information.
We recommend Hill Labs. Contact the laboratory before collecting a sample and follow its instructions for containers, collection, storage and delivery.
Keep your system working well
Looking after your water source is just as important as maintaining the treatment equipment.
Keep roofs, gutters and leaf screens clear. Check tank lids, screens and bore seals, and prevent animals and surface runoff from entering the supply.
Replace filter cartridges and UV lamps according to the manufacturer’s schedule. Clean the UV sleeve as instructed and investigate alarms or changes in performance promptly.
Need help choosing?
Tell us where your water comes from, what you’d like to improve and how much water your household uses. If you have water-test results or photos of your existing system, send those through too.
We’ll help you choose equipment suited to your supply.
