Genuine Heatrae Sadia 95605817 Megaflo Cold Water Combination Valve Kit

Genuine Megaflo Cold Water Combination Valve Kit

The Heatrae Sadia 95605817 Cold Water Combination Valve Kit is a genuine replacement assembly for compatible older Megaflo unvented hot water cylinders. It combines the principal cold-water inlet pressure-control and expansion-safety components required by the cylinder installation.

This kit is commonly associated with earlier Heatrae Sadia Megaflo cylinders manufactured between approximately 1995 and 2001, including models with an internal air volume. Because several generations of Megaflo cylinder use visually similar but technically different valve assemblies, the complete part number and cylinder data label should always be checked before ordering.

What Does the Combination Valve Do?

The cold water combination valve controls the incoming mains water supply before it enters the unvented cylinder. Its pressure-reducing section limits the incoming pressure to the level required by the system, while the check valve prevents reverse flow. The expansion relief valve provides a controlled discharge route if pressure rises beyond its specified operating level.

The balanced cold-water connection can be used to supply compatible mixer outlets at a balanced pressure, helping maintain more consistent hot and cold water performance.

Compatibility

Part 95605817 is commonly specified for older Heatrae Sadia Megaflo cylinders with an internal air volume, including certain models manufactured between approximately 1995 and 2001. Current Heatrae Sadia parts information also associates this part number with certain PremierPlus installations.

Do not select this valve solely from its appearance. Compatibility should be confirmed using the part number on the existing valve, the cylinder model, serial number and data label. Later Megaflo generations may require a different cold water inlet control kit.

Installation Information

This is a safety-critical component for an unvented hot water system. Installation, commissioning and testing must be completed by a suitably qualified engineer in accordance with the cylinder manufacturer’s instructions and current regulations. The relief outlet and connected discharge pipework must never be capped, blocked or restricted.
