    Plumbing addition

    So I plumbed my black tank flush into the plumbing in the basement. Vacuum breaker is still in place plus I added an inline check valve just for extra safety.
    Planned on adding a picture of the valve, but don’t see a way to do it from my phone.

    The check valve defeats the purpose of the vacuum breaker. Water actually needs to he able to backflow out of the inlet to drain the line out.
