Black tank valve leaking
Hi all, new Sierra 380bh5 with enclosed under belly and has a remote valve control at the docking station. Over the course of two days it leaked about two cups of fluid past the valve so when i pulled the cap off, you can guess what happened next. Is there a way too adjust these valves or fix this without taking to dealer? I've run the tank flush incase debris was an issue plus 10-15gal of water thru toilet and still not holding.
