PYS dripless seal leak
I have the PYI seal and it has been working great for 5 years. If you pull back on the rubber bellows away from the stainless doughnut on the shaft, it will leak. At one point, some crud built up on the stainless doughnut and as per the manufacturer suggestion, I removed it from the shaft and cleaned it with 600 grit sandpaper. No problems since that time.
