A good configuration starts with the site, not the catalogue.
Start with the site
Whether it is an office, a hospitality venue or a remote facility, the right system is defined by the water and how it will be used.
1. Feed water
Start with the source: mains, bore or tank. A recent water test helps (TDS, hardness, alkalinity, iron and manganese where relevant). The water report and the intended use should be assessed together by a suitably qualified person. A few results on their own do not show that water is safe to drink. Don't have a test yet? Contact us anyway and we can talk about next steps.
2. Demand profile
Daily volume and peak draw determine system size and any storage. A commercial RO rating, such as litres per hour at a stated temperature, can fall in colder water, so allow for that.
3. Point of use or point of entry
Drinking water at one tap, a whole building, or process water for washing or equipment are different briefs.
4. Site services
Check pressure (a PRV may be needed), power supply, drainage for concentrate or backwash, space and access.
5. Maintenance and consumables
Agree replacement intervals, access for servicing and who supplies cartridges and media over the system's life. Include this cost when comparing options.
6. Compliance and installation
Use a licensed plumber or electrician where required, and follow local rules. Check which certification applies to each model. The ADWG is the national guideline (NHMRC, Version 4.0, June 2025). It is not legislation; legal requirements come from state and territory law and from water suppliers [1][2].
Key buying implications
- Size the system to measured demand and the actual site conditions, not to catalogue headlines.
- Include consumables and servicing in the cost comparison.
- Confirm compliance requirements for each model and each location.
Starting an enquiry
Helpful to send, if you have it: location, water source, any test results, application, daily and peak demand, available services, and any tender or documentation requirements. If some of these are unknown, a short message is enough to start.
