Anti freeze in water heater

When the tech winterized our MH, the anti freeze went through the water heater ( check valve failed).
Is it OK to wait until we dewinterize in the spring to flush out the water heater? (our MH is in storage).
Thanks

    As drewE said, as long as it's just antifreeze. If it's a mixture of water and anti freeze it becomes a question of what is the mixture strength. If in doubt drain it out and properly winterize it.

    No problem, assuming it's just antifreeze and not filled with water and a touch of antifreeze. The main reason to bypass the water heater is to avoid having to buy and pump in six extra gallons of antifreeze; it's not harmful to the plumbing system, including the water heater.
