... when I pulled the Head, I immediately saw the problem. Because of my configuration, I had to install the discharge line to the back of the toilet before installing this hose to my Y-valve. When I installed the hose to the Y-valve, I must have twisted it just enough to slightly kink the soft rubber molded hose in back of the Head. So, there was an obstruction.
The new Marine Elegance is elegant. The folks at Raritan make some very nice products. I am a happy camper now. I think we will be very happy with this new electric Head !
Thanks for all the help Peggy and Steve ...
Cheers, John
