I've got my Stenner pump on-line now and watched it for its first pumping cycle not only to see how it performs but whether the timer that controls it works also. During the pumping cycle, the discharge side of the Stenner pump tube at the tube housing wiggles side to side in the pump head. Not a crazy amount but as the rollers squeeze the tube there is a pretty good motion. Additionally the discharge tubing leading to the injection check valve moves in a slight "jumping" motion in rhythm with the movement of the tube at the pump head as the fluid is delivered.
Are these movements normal and to be expected?
I just want to make sure that the injection check valve is not blocked as I never did test the system before the installation.
