What it is
The Alpha diverter and flow valve seal kit is a set of seals, O-rings, gaskets and washers used to reseal the diverter and flow valve assembly on Alpha boilers. It is supplied by Alpha under part number 3.013391 and sits in the gaskets, O-rings, seals and washers category. The seals sit at the joints and ports of the valve body, keeping water contained within the assembly during domestic hot water and heating operation.
Signs this part needs replacing
- Water weeping or dripping from the diverter and flow valve body
- Damp staining, corrosion or limescale trails around the valve joints
- Seals that look flattened, hardened or cracked when the valve is opened
- Scale or debris preventing the seals from seating correctly
- Loss of system pressure traced back to the valve assembly
Before you order
- Match part number 3.013391 and the GC number for your appliance against the compatibility list.
- Earlier number 3.013163 may appear on older documentation for the same kit.
- O-rings, gaskets, seals and washers are specific to a location within the boiler and are rarely interchangeable, so confirm the kit suits the diverter and flow valve on your model.
- Have the boiler GC number and serial number to hand when ordering.
