Can I install a check valve in my washing machine drain line?

I get that bad drain smell during/after using the washing machine. I don't think my trap is adequate, but I am limited by how the drain is installed (just above my concrete slab floor...can't go higher because the drain line in running alongside/in the skirt of a bath tub). Will the washing machine discharge have enough force to open the check valve? Will this stop the sewer smell? Thank you much. Let me know if you need any additional information.

Welcome to the forums.

It sounds like there may be a vent issue at your washer. A check valve on the line won't be effective. You can't restrict the washer line with a check valve and I would think that the lint would build up on it and render it inoperative and not sealing.

Does the trap have water in it now ?
