I saw the video on how to replace the levers on your site and quickly order the replacement part for my unit. It turned out just like the video and I was able to complete the removal and installation in about 45 minutes (that included the cleanup that was required) after old stained parts were removed. The plastic water tube had hard water deposits near the opening which I was able to remove with a soft wood dowel rod. Everything went as planed and when I turned the Circuit breaker back on it worked like new again.
The one thing I wish that could have and would have was. The type of plastic these parts are made of. A very hard slick surface much like a ceramic or epoxy that would or could be wiped clean and remain stain free.
