Product review (5 stars): A better Design.
The black thing coming off the assembly is a drain hose. My old one did not have this so I was not sure it was right for my machine. It was a great add to the assembly as the old one had much more water in it than I expected so I was sopping up water for a lot longer than I wanted to. Now I can direct the trapped water into an oil drain pain and save a ton of work. I fed the hose through the front so can access that first to empty the assembly unattended and work on a dry floor. The pump comes with this and I thought I would save the old one but once I separated the pump it smelled like a newly opened septic tank, water was leaking in the pump for a long time and I was glad to have the new one.
