Product review (5 stars): Fernco rules.
Yeah! You can't beat a Fernco. This not only worked for my washer outlet/downpipe, but it also worked to connect a tub drain pipe into a larger floor drain pipe, believe it or not--several months of draining the tub with no problems whatsoever. One thing to be aware of--the screw on the clamp DOES stick out about 3/4 of an inch--make sure you have clearance with the wall, other pipes, whatever.

Expect me to check back in five years to say my two Ferncos are still going strong. Nice sturdy rubber, strong clamps that I don't think will rust--but if they do, I'll let you know.

Go Fernco!
