Black tank flush out pump and inlets
I bought a "Camco Antifreeze hand pump." I tried to pump antifreeze into the "sewer tank flush" inlets.
On the front tank, I pumped about 1/3 gallon in, so I'm pretty sure that there's antifreeze throughout the pipe all the way to the black tank. However, when I unscrewed the pump's tubing, a bunch of antifreeze came back out. I thought that there's a check valve in there that's supposed to prevent backflow?
On the rear tank, the inlet would not let any antifreeze in. It appears to be blocked internally. I pumped and as soon as the pump's tube was full, it wouldn't let me pump any more. I tried to pump harder and it popped the tube off. I'm ASSuming that the check valve is malfunctioning or that the tube / pipe is blocked somehow. How do I rectify?
Am I supposed to do something special to make these flush inlets work?
Thanks in advance for the help!
