    Default Washer discharge configuration

    Is there any instance where it is acceptable to route a washing machine discharge into a one way flow valve and have it pump up into the main sewer line?

    I am thinking no but wanted to verify with everyone.

    I would think recommending a gray water ejector pump would be the proper solution.

    Ah, the "check valve solution"
