At the hot water outlet of your water heater, I'll bet there's a check valve like this one:
It's pretty small and not very conspicuous but if you've got a single handle water heater bypass, you've got one of these valves. The disk that prevents the backflow of water into the heater is plastic and held in place with a small rivet. That rivet pulls through the plastic and plugs up the outlet to the heater.
Be careful selecting a replacement. I was able to find one with a brass disk instead of plastic. It was the same brand but I'm not sure if it had the same part number.
