Tom...
Thanks for the help. Over the weekend, I tried the vacuum cleaner hose over the inlet .. for the Blackwater Flush. It WORKED!. I did it a couple of times, for a second or two and then inserted water into the inlet. All is fine.
I have heard, that there was a sprinkler type mechanism inside the Blackwater tank that you could hear when inserting water. Although I heard water come into the Blackwater tank, I could not hear any 'sprinkler type' action inside.Dave & Becky

Glad it opened for you. The sound I get is more like a spray hitting plastic tank walls. I hear a sound from the vacuum breaker valve and a separate sound of the spray in the tank.
I also cycle the tank flush by turning it on until I get a good flow, then turn it off until the flow is almost gone. Then I flush again. The reason is that when I leave it on the discharge starts to appear clear like the tank has been thoroughly flushed. But, if I let it drain and reflush I get more waste debris. I assume that the tank fills a little faster than it drains which covers wate material and keeps the spray from hitting it directly.Tom and Tanya

So on a 2015 303 RLS how do I access the black take flush vacuum breaker? I believe mine is failed because when I use it I get external leakage near the water heater and sometimes water seeps from under the shower floor pan into the bathroom.
