Something dosent add up here.
If you can push it back into the shower,it should drain the other way too.
Have you tried a drain snake or even maybe a coat hanger to prove the valve is open?
Measure it along the outside and see if you can push it past the measured distance.
I still think the valve is closed.
Not sure what doesn't add up, it's probably just my explanation. The valve works fine, it's only 6 inches to the valve, and I shoved almost 10 feet of hose up the pipe so that should demonstrate the valve is open. I did use a plumbing snake, ran that up 15 feet from outside and from inside using the shower drain. I snaked for over 20 minutes and didn't penetrate whatever it was that was blocking the tank. When I used pressurized water on the FULL tank, from the outside it just pushed it up into the shower and wouldn't drain back out. When I tried using pressure from inside, into the shower drain, it bubbled back into the kitchen sink. Pressure did not work, period.
So, I called the Pros from Dover. More to follow....
