In today’s fast-paced construction and renovation environments, efficiency, compliance, and reliability matter more than ever. Enter the Zetco Under Sink Manifold range — a game-changer in Australian plumbing that simplifies kitchen and bathroom installs while ensuring long-term performance.
Whether you’re roughing in a new build or retrofitting a compact apartment kitchen, this guide explains why Zetco’s WaterMarked under sink manifolds are the go-to choice for plumbers nationwide — and how to choose the right one for your job.
🔧 What is an Under Sink Manifold?
An under sink manifold is a compact valve unit that distributes water from a single inlet into multiple outlets — often cold and hot water lines feeding taps, dishwashers, filtered water units, or washing machines.
Rather than installing multiple tees, isolation valves, and elbows, a manifold combines everything into a neat, efficient, code-compliant block.
Zetco’s range stands out thanks to:
-
✅ WaterMark certification
-
✅ Forged brass construction
-
✅ Australian Standard thread types
-
✅ Compact size for tight cabinet spaces

💡 Pro Tip: Use Manifolds to Future-Proof Your Fit-Offs
With new apartments and homes adding filtered water taps, chilled fridges, and smart dishwashers, it's smart to pre-install manifolds with spare outlets. It costs a little now but avoids rework later.
And if you're dealing with builders? A clean, brass manifold install beats a spaghetti mess of tees and mini taps every time.
