Setup, Compatibility & Care
To install, first isolate the water supply to the toilet and flush the cistern to drain any remaining water. Remove the valve assembly according to your specific Siamp model instructions. Carefully remove the old washer, clean any debris or mineral buildup from the seating area, and place the new Oracstar 29mm washer into position. Ensure it sits flush before reassembling. For care, avoid using harsh chemical cleaners directly on the washer, as this can degrade the material. Regular visual inspections during routine cleaning can identify if the washer has become brittle or deformed over time.
