While these worked great for us, they have been sitting on our garage shelf for about 10 months. The only reason we don't need them any longer is that we upgraded to a larger model. They were professionally installed and uninstalled by a certified plumber, but I am unable test them out, so in good conscience I am listing ---as is only . They were originally $800.00+ a piece- I am asking $100.00 OBO for the pair. I do still have the instructions.
