Black tank flush not working

Hey guys,

My black tank flush has not been working for the last two camping trips. I just finished replacing the vacuum breaker and check valve and there is still no change.

This is what happens. When I turn on the water for the black tank flush you can hear the water line build pressure for about a second and then nothing happens.

Does anyone have any suggestions as to what to do next?

2015 Salem hemisphere 312qbud

Thanks
Jason

Last campground I was at had really low pressure on the hose at the dump station. My black tank wouldn't flush so I flushed it when I got home and it worked fine.

I have tried two campgrounds that it previously worked at and have tried at home as well. I don't think it is a pressure issue.

Not too uncommon to find the check valve installed backwards. I know you said you just changed that but might not hurt to make sure.
It's about gotta be that or the whole hose is plugged at the spray end. In which case case you'll have to gain access to where it attaches to the tank.

Did you check the screen on the hose connection?

X'2 the only thing it really could be, unless your hose collapsed or kinked somewhere. They have alot of extra hose on those flush systems.

The nice thing about the location of the vacuum break is that it is right where the tank flush connection is. It is definitely installed the correct direction. I guess it must be a kink in the hose. I will play around with the hose later today to see if I can wiggle the hose enough to make it work

There is a USB snake camera on Amazon for less than $25. About 10 feet long and has led lights. Would be great for looking in those hard to reach areas when a problem arises.
