What it is

The Worcester Bosch 87182214710 is a 6 bar safety relief valve with a DN20 connection. It is fitted to Worcester Boulter Buderus appliances to relieve excess system pressure and protect the appliance and associated pipework. The valve opens at its set pressure and closes again once pressure returns to normal operating limits.

Signs this part needs replacing

  • Water weeping or discharging from the valve outlet when system pressure is normal
  • System pressure rising above the normal range without the valve opening
  • The valve failing to reseat and continuing to pass water after it has opened
  • Scale, corrosion or debris visible around the valve seat or outlet
  • Boiler losing pressure repeatedly with no other visible leak

Before you order

  • Confirm your appliance model matches the fitment listed above
  • Check the existing valve is rated at 6 bar with a DN20 connection
  • Isolate the appliance and depressurise the system before removal
  • Inspect the valve seat and outlet for damage or debris before fitting
