I bought this product on a whim and wanted to test it out to see if it could clean my sewer hose better than just using a hose. To my surprise it did! Attaching this adapter to the end of your rinse hose and then connecting it to your sewer hose kept all of the rinse water in the sewer hose and not splashing up into my face or on my hands. Easy to use and even has a shut of valve to stop the flow of water when you are done rinsing. The adapter splits the water stream up into four jets that stream down the sides of your sewer hose removing all of the nasty stuff, and flushing it down the drain. If you are tired of getting splashed by your rinse water then this is the product for you.
