Black tank flush not working
I had a problem once which was I had my pressure regulator connected while trying to flush tank. Very little water was going to tank. Took off regulator and problem solved. Must have built up more than 55psi and shut down the flow. Regulator had worked fine all weekend and all camping trips since.
