What it is

The Gledhill SG019 is a pressure and temperature relief valve for unvented hot water cylinders, fitted as a safety device that discharges water automatically if pressure or temperature exceeds pre-set limits. It has a brass body and is rated for residential and commercial unvented systems.

Signs this part needs replacing

  • Water weeping or dripping continuously from the valve discharge outlet
  • Valve fails to reseat and stop discharging after opening
  • Visible corrosion, scale or limescale build-up on the valve body
  • Cylinder pressure or temperature reading abnormally high

Before you order

  • Match the part number printed on your existing valve before ordering
  • Isolate and depressurise the cylinder before removing the old valve
  • Unvented hot water systems must be worked on by a competent (G3-qualified) engineer
