Why Great Water Filters Hornsby?
Years of Business
Installing a Whole House Water Filter in Hornsby is a reliable way to ensure clean, safe, and pleasant-tasting water for every tap, shower, and appliance in your home. One integrated system protects your plumbing while providing high-quality water for everyday use.
Hornsby’s mains supply is managed by Sydney Water and drawn from the Warragamba and Upper Nepean systems. It is typically medium-hard, with seasonal variation and occasional chlorine or metallic taste from pipelines. Our systems are designed to refine this supply, reducing sediment, odour, and chemical traces for fresher, softer water.
Our Hornsby range includes UV purification, multi-stage filtration, and optional softeners—ideal for properties using mains, rainwater, or bore water. Homes using tanks can also receive a complimentary $500 UV or softener upgrade to improve clarity and protection.
With interest-free payment plans and free installation across Hornsby and the Upper North Shore, upgrading your home’s water has never been easier.
Upgrade your home today with Whole House Water Filters in Hornsby and enjoy the assurance of cleaner, purer water.
