If your Siamp Optima 49 or Optima 50 flush valve won't seal properly and is constantly passing water into the toilet pan but there is no sign of an inlet valve failure, it could very well be that the base sealing washer need to be changed. Overtime as the flush valve is opened and closed, small imperfections tend to occur in the surface of the rubber washer causing the washer to be warped and not providing an adequate seal. Many make the mistake of purchasing a full replacement flush valve at the first sign of any issue, replacing just this washer may save you a lot time and money in the long-term. We advise purchasing a couple of these washers at a time so you've got one readily available in the event that the washer fails again in future.
