I haven't had a chance to try the flush system again. Originally, when I posted, the temperatures outside were in the low 30's. I'm hoping, with the warmer weather, it will work. I did call the dealer where I bought the tt and they suggested checking the hoses under the sink, in case they loosened. In any event we won't be able to go back to the tt until late next week. I will post the results when I try it again. One thing for sure......very difficult to access the hoses where they are located.
