What it is

The filling hole cap 7810670 is a Baxi component that seals the filling loop connection point on the appliance. It closes off the filling hole on the isolation valve assembly, preventing water loss once the boiler has been filled and pressurised. It is used across the Baxi Combi 2 range.

Signs this part needs replacing

  • Water weeping or dripping from the filling hole after the loop has been disconnected
  • The cap is missing, cracked or distorted
  • Scale or corrosion visible on the cap or its sealing face
  • The cap will not tighten down or hold pressure
  • System pressure drops steadily with no other visible leak

Before you order

  • Confirm your boiler model against the fit list above
  • Check whether the cap alone is required or the complete isolation valve assembly
  • Inspect the sealing face and thread on the valve body for damage before fitting a new cap
