IF bypass was issue then you would get cold water flow out of hot water side of faucets
If water heater was still filling you would get spurts of air/water out of hot side of faucets
Check valve in water heater HOT out is clogged up.
It is a cheap plastic plunger/spring/o-ring assembly that easily fails/clogs
Especially when water in water heater is old rusty scaly water.
Drain and thoroughly flush water heater tank
Replace anode rod if you water heater is a SUBURBAN (Atwood doesn't use them)
Remove hot line fitting at water heater (check/clean inside of fitting)
Remove 'nipple' in hot out on WH Tank.....check valve is internal of nipple.
Replace with new check valve
