Outside black water tank flusher
Problem!!! When I connect hose to outside black water tank flusher, I hear no water running and get no water discharge out of sewer drain. Can this be replaced?? Is it clogged?? If replacing, is it a very hard thing to do?? Tks in advance for any info!!!

fonzie has given you good advice.
Has it ever worked?
Many vacuum/break valves are plumbed backwards from the factory.
Many leak from the factory.
Most folks will replace the inexpensive plastic ones with higher quality brass valves.

When using the black tank flush should we still use the regulator?
Thanks again

I have never used the pressure regulator when flushing. And it goes without saying to NOT use your regular water hose to flush with.

Correct. Having to unscrew hoses from regulator was part of the question.
Thanks

I think the black ones are rated to 125psi and the clear ones are rated to at least 200psi. But of course, one never knows for sure. Probably best to be safe than sorry.

I had an external plastic backflow preventer that blew apart from too much water pressure. I replaced it with a brass unit but when we go back to that Provincial Park I may use a dedicated pressure regulator, too.

I bought our TT used and discovered that the previous owner must have had the black plastic backflow preventer break because he had replaced it with a bend.
(Sorry the picture is sideways.)
