Received a replacement seal within 2 days. After reading other reviews it was so easy to turn off the main water faucet in the house, open a few taps and then remove the top and bottom plates on the water softener bypass. The old seal was deformed from being in one position for a long time (about 20 years) and came out fairly easily, although it left black rubber "soot" on my hands and wherever I put it. I cut the new gasket in half lengthwise and screwed it into the bypass, shaping it with a screwdriver handle and installing it correctly. Screw the panels back and left. No leaking, no hissing.
