What it is
The Biasi BI1426107 is a stainless steel washer measuring 5.3mm x 12.5mm, supplied for Biasi gas boilers. It is fitted at a sealing joint on the Garda HE PLUS and RIVA Advance HE M110 ranges, where it compresses to close the joint against water loss. Stainless steel construction resists corrosion at a wet connection point.
Signs this part needs replacing
- Water weeping or dripping from the joint the washer seals
- Visible corrosion, pitting or discolouration on the washer face
- Washer flattened, split, cracked or otherwise deformed
- Scale or debris trapped on the sealing face, preventing a clean seal
- Repeated pressure loss traced back to the joint
Before you order
- Confirm your boiler model against the fit list above
- Check the existing washer measures 5.3mm x 12.5mm before ordering
- Check how many washers the joint requires, as more than one may be needed
