Frequently Asked Questions
Q: Which Geberit flush valves is this seal washer compatible with?
A: This silicone rubber flush valve seal washer is designed to be suitable for all Geberit flush valves. Its standard dimensions (63 mm outer diameter, 33 mm inner diameter, 3 mm thickness) match the base sealing seat across the Geberit range. If in doubt, measure your existing washer before ordering.
Q: What is the difference between silicone rubber and standard rubber for flush valve washers?
A: Silicone rubber offers superior flexibility and durability compared to standard rubber. It resists degradation from prolonged water exposure, temperature fluctuations, and mineral deposits, helping the washer maintain a consistent, watertight seal for longer.
Q: How do I install the flush valve seal washer?
A: Turn off the water supply to the cistern, flush to empty the tank, remove the existing flush valve assembly, swap out the old worn washer with the new silicone seal washer, reassemble the valve, and restore the water supply. No specialist tools are required for most standard Geberit cistern setups.
Q: Why should I buy a multi-pack (3 or 5 pieces)?
A: Seal washers are consumable parts that naturally wear over time. Buying a 3- or 5-pack means you always have a spare on hand for quick future maintenance, saving you time and additional shipping costs down the line — especially useful for households with multiple toilets or for trade professionals.
