Brisbane tap water quality
SEQ water uses chloramines (combined chlorine + ammonia) as the primary disinfectant — more persistent than free chlorine and requires specific carbon block or catalytic carbon filters to remove effectively. Standard carbon filters designed for free chlorine may be less effective on chloramines.

Getting quotes in Brisbane
Getting 2–3 quotes from different suppliers in Brisbane is the most important step before committing. Filter installation pricing varies between generalist plumbers and dedicated water filter specialists — and the quality of system specification advice varies even more.
- Confirm WaterMark certification on any product before purchase or installation
- Ask for an itemised quote — unit cost, installation, tap (if required), and ongoing cartridge costs separately
- Confirm the plumber holds a current licence for your state — check the relevant licensing board
- Ask specifically what the system removes — get a specification sheet, not just a brand name
For most Brisbane homeowners on town mains water, an under-sink carbon block filter or a 5–7 stage reverse osmosis system is the most popular choice for drinking and cooking water. Whole house systems are more common among homeowners with QLD bore or tank water sources, or those specifically concerned about chlorine in shower water. See our filter types guide for help choosing.
