What it is

The Buderus drain plug is a threaded plug used to seal a drain or bleed point on the appliance. It is supplied by Buderus as a pack of five under part number 7100905. The plug has an 18mm size and is intended for use on Buderus 800 series appliances.

Signs this part needs replacing

  • Water weeping or dripping from the plug when the system is under pressure
  • Corrosion, rust staining or scale build-up visible on the plug head or threads
  • The plug will not tighten fully or the threads are damaged
  • Seal faces marked or deformed, allowing a persistent weep after refilling
  • Plug missing or lost after draining down the appliance

Before you order

  • Check the appliance model against the fit list above to confirm compatibility
  • Confirm the port takes an 18mm plug before ordering
  • Note that the plug is supplied as a pack of five, so a single pack covers multiple drain points or future servicing
