What it is

The Relief Valve And T Piece is a Heatrae Sadia component supplied under part number 7724178. It combines a pressure relief valve with a T piece connection, and is listed for use across Heatrae Sadia products. The relief valve provides a controlled discharge path when system pressure rises above its set limit, protecting the appliance and associated pipework.

Signs this part needs replacing

  • Water weeping or dripping continuously from the valve discharge outlet
  • The valve failing to reseat and hold pressure after it has lifted
  • Visible scale, corrosion or debris around the valve seat or T piece joint
  • Leaks at the T piece connections or surrounding pipework joints
  • System pressure that will not hold steady during normal operation

Before you order

  • Confirm your appliance model against the manufacturer's parts list
  • Check the existing valve and T piece arrangement matches the layout of this assembly
  • Verify the part number 7724178 against the component currently fitted
  • Ensure any discharge pipework is routed correctly before fitting a replacement valve
