Designed for larger households and high water usage, this is a high-flow, high-performance whole house filtration system built for reliability and long-term durability.

Australian WaterMark Certified

This product is 100% tested, certified and awarded Australian WaterMark approval, meeting strict Australian plumbing standards.

Australian plumbing codes require WaterMark certification before a licensed plumber can legally install a filtration system in your home.

When you choose Water Filter World, you gain peace of mind knowing:

• Your system complies with Australian plumbing regulations

• It is rated to withstand Australian mains water pressure

• All components are independently tested and verified

Unfortunately, many homeowners have experienced costly flood damage after installing cheaper, non-WaterMark approved systems purchased online. This system is built to prevent that risk.

Now Upgraded

✔ Includes Solid Brass Ports – Tough as Tonka
✔ Built for high-pressure Australian conditions
