The red seal is supposed to be rubber where as the original American Standar seal was/is silicon which was the problem. However, I t would be great to know if the red seal lasts the test of time? Being rubber it should not blister like the silicone, is the hope. I see the valve replacement options to resolve the original equipment bad flawed seal issue but that would only seem necessary if th eflush doea not remove the waste sufficiently. I think the toilet does fine (we have three Champion 4's that all ghost flush) with flushing unless water in the tank gets past the seal which reduces flushing capacity. This may lead people to replace the valve because the feel the toilet flushes poorly. I was also going to replace a valve on one of ours but maybe if the red seal does the trick, and does not have to be replaced every 6 months like the A.S. replacement then that would be the most economical option.
