Tried to winterize for the first time using the pink antifreeze method. Started by draining the wh, turning the bypass valve on, switching the 4 position Anderson valve to winterize, turning on the water pump at the same time the hose was inserted into a gallon of antifreeze. All the antifreeze pumped into the wh. WHAT HAPPENED?

thanks for your input

Sounds like the bypass valve didn't actually operate, or the check valve at the hot water outlet from the water heater is stuck open.
