Product review (3 stars): I wish it worked
This looks like a simple and clever solution to a potentially large flooding problem and hopefully it will work for some.

Unfortunately it didn't work for me. My washing machine just refused to run properly until I put back the old hoses. I had even tried removing the flow restrictors and that didn't help

I gave it three stars in case someone knows a solution to my problem since I would still like to be able to use the hoses
