Washer discharge configuration

[Jon mackay]

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" :rolleyes:

There seems to be no limit to DIY creativity (not even gravity).
