What it is

The Andrews O-ring P20C is a sealing component listed for Andrews water heaters. It sits within the Andrews hot water spares range and is specified for the Fastflo LWH42, LWH56, WH42 and WH56 models. The O-ring seals a water-carrying joint in the appliance to prevent leakage.

Signs this part needs replacing

  • Water weeping or dripping from the joint the O-ring seals
  • Visible cracking, flattening or deformation of the O-ring
  • Hardened or brittle rubber that no longer seals under pressure
  • Scale or debris build-up around the O-ring seat
  • Leaks that return shortly after the joint is tightened

Before you order

  • Confirm your appliance model against the fit list above
  • Check the part number P20C against the O-ring being removed
  • Inspect the O-ring seat for damage or scale before fitting a new seal
  • Isolate the water supply and depressurise the appliance before starting work
