What it is

The MANIFOLD, BRASS (SAFETY GROUP) is a brass manifold assembly used as the safety group component on Vaillant unvented hot water cylinders. It forms part of the cylinder's safety arrangement, combining the pressure and temperature relief connections into one manifold body. It is supplied as a single brass manifold unit for the Vaillant Vantage and VIH GB ranges.

Signs this part needs replacing

  • Visible corrosion, scaling or pitting on the brass manifold body
  • Water weeping or dripping from manifold joints or connections
  • Discharge from the safety group that continues without the cylinder being heated
  • Seized or damaged connections that will not seal when the relief valve is reconnected
  • Evidence of frost damage or cracking around the manifold ports

Before you order

  • Confirm the cylinder model matches one of the fitment listings above
  • Check the existing manifold for the same connection arrangement and port layout
  • Identify the cylinder serial and model plate before ordering to avoid a mismatched assembly
  • Confirm whether the safety group is being replaced as a complete assembly or the manifold alone
