What it is

The 4 Bar 15mm x 1/2'' T&P Relief Valve is a temperature and pressure relief valve in the Popular Cylinder Spares range, listed under cold water inlet controls. It discharges water when the cylinder temperature or pressure reaches the valve's 4 bar setting, protecting the cylinder and associated pipework. It is used on the Gledhill Accolade cylinder family and Popular Cylinder Spares cold water inlet control assemblies.

Signs this part needs replacing

  • Water discharging from the valve outlet or tundish when the cylinder is not overheated
  • The valve weeping or dripping continuously and failing to reseat
  • Scale, debris or corrosion visible at the valve seat, body or connections
  • Repeated discharge indicating the valve is opening below its 4 bar setting

Before you order

  • Confirm the replacement rating matches the cylinder's requirement of 4 bar
  • Check the connection sizes, 15mm x 1/2'', against the existing valve and pipework
  • Check the appliance model against the fit list above
  • Work on unvented cylinder controls should be carried out by a competent person
