Biasi Riva 24S 24SR 28S Diverter Valve Repair Kit BI1011504
Product Overview
The Biasi Riva Diverter Valve Repair Kit (Part Number: BI1011504) is a replacement repair component kit designed for selected Biasi heating systems.
Part number BI1011504 is identified as a Diverter Valve Actuator Repair Kit, associated with the boiler's three-way diverter valve mechanism.
The diverter valve directs heated water between the central heating and domestic hot water circuits, allowing the boiler to respond to the required operating demand.
The repair kit is intended for servicing the associated diverter valve actuator mechanism without necessarily replacing the complete diverter valve assembly.
ℹ️ Product Condition Options:
This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished components should be professionally inspected and tested to confirm their condition and correct operation before installation.
Technical Insight & Common Failure Symptoms
The three-way diverter valve mechanism controls the direction of heated water within the boiler, switching between central heating and domestic hot water operation according to demand.
Mechanical wear, damage or deterioration affecting the diverter valve actuator mechanism may prevent the valve from moving correctly.
Possible symptoms that may indicate a diverter valve or actuator mechanism problem include:
-
Central heating working but domestic hot water not heating correctly.
-
Domestic hot water working while central heating fails to operate correctly.
-
Intermittent heating or hot water operation.
-
Diverter valve failing to change position correctly.
-
Mechanical wear or damage affecting the actuator mechanism.
-
Difficulty switching between heating and hot water functions.
-
Valve mechanism sticking or failing to operate smoothly.
These symptoms do not necessarily confirm a faulty diverter valve actuator mechanism, as similar problems may result from internal valve components, electrical controls, hydraulic restrictions or other boiler components. Correct professional diagnosis should be carried out before replacement.
Compatibility
This part (MPN: BI1011504) is associated with selected Biasi Riva 24S, 24SR and 28S boiler systems.
Please verify the boiler model, original part number and repair kit specifications against the manufacturer's technical documentation before ordering to ensure correct fitment.
Safety Advice
Boiler diverter valve repair kits and associated hydraulic components should only be inspected, removed or installed by a suitably qualified and competent heating engineer.
Always isolate the appliance and allow the heating system to cool before carrying out any work. Where servicing involves opening the hydraulic circuit, the system must be safely isolated and depressurised. Follow the manufacturer's servicing instructions and complete all required leakage, pressure and operational safety checks before returning the boiler to service.
