What it is

The Ideal 176748 is a temperature and pressure relief valve rated at 6 bar. It is a safety device fitted to unvented hot water cylinders and commercial heating systems, designed to open and discharge water if the pressure or temperature exceeds safe operating limits. This protects the cylinder and associated pipework from damage or failure.

Signs this part needs replacing

  • Water discharging from the relief valve discharge pipe when the system is not overheating.
  • System pressure consistently rising above the set limit.
  • The valve fails to hold pressure, causing frequent top-ups.
  • Visible scale, corrosion, or debris around the valve seat.
  • The valve does not reseat properly after manual testing.

Before you order

  • Confirm your appliance model and serial number against the compatibility list.
  • Check the existing valve's part number; 176748 is the current number.
  • Note the alternative part number 1782874 for cross-reference.
