When it comes to compliance, safety, and clean drainage in hot water installations, tundishes are non-negotiable.

Let’s break down why this little device is essential — and why plumbers across Australia are choosing the Allproof version for speed, reliability, and compliance.
💡 What Does a Tundish Do?
A tundish is a critical plumbing component that provides an air gap between the discharge pipe from a hot water relief valve and the drainage system. This air gap is required under AS/NZS 3500 to prevent backflow and contamination — especially important in potable water systems.
The Allproof Hot Water Cylinder Tundish provides a visible means of discharge, meaning any overflow or valve failure can be easily spotted by a plumber or homeowner. This reduces risk and simplifies maintenance.
