The SIAMP OPT 49/99 Dual Flush Valve Pack with AirGap Low Pressure Fill Valve is a toilet cistern repair pack for compatible WC cistern installations. It is designed for replacing worn, sticking, damaged or faulty internal cistern parts where the flush valve, fill valve or button assembly is no longer working correctly.

This pack contains the key internal parts needed for a compatible cistern flush and fill repair. The product reference is 10006064 and the product name is Pack Dual Flush OPT 49/99 AirGap Basse Pression. Basse pression means low pressure, so this version should be used where a compatible low pressure fill valve is required.

The OPT 49/99 dual flush valve controls the flushing action inside the cistern, while the AirGap low pressure fill valve refills the cistern after flushing. The pack is supplied with a chrome dual flush push button, seals, fittings and installation guidance as shown, making it suitable for plumbers, property maintenance teams, landlords, facilities teams and competent DIY users carrying out toilet cistern repairs.

This product is suitable for use in domestic bathrooms, rental properties, offices, commercial washrooms, schools, care homes and general maintenance environments where compatible cistern internals need replacing. It is a practical repair pack for restoring normal flush and refill operation in suitable WC cisterns.

Although the SIAMP OPT 49/99 pack is designed as a universal adjustable repair solution for many compatible toilet cisterns, it should not be assumed to fit every cistern. Toilet cisterns can vary by internal height, outlet hole size, lid hole diameter, button position, inlet valve connection and water pressure requirement. Before ordering, compare your existing valve, cistern measurements, push button setup and low pressure water supply requirement with the product details and images. Installation should be carried out by a competent person or qualified plumber where required.
