Product review (2 stars): Product was genuine GE part but only a temporary fix
Product was a genuine GE part per packaging and fixed washer drum leak. It sometimes makes a humming noise when water passes through it but my washer is old and it may be a vibration from another part.

UPDATE, 2mos later:  part has stopped working properly (sounds like valve(s) getting temporarily stuck when water starts filling tub at different points in the cycle), so have downgraded to 2 stars from 4 stars just to provide the benefit of a doubt regarding source of problem.
