I maintain my Stenner pump by replacing the white tube inside the unit periodically. Today, seeing some algae in the pool, I checked my chlorine. ZERO. Usual diagnostics lead me to my Stenner not moving fluid. Checked the intake line and the output line. Neither is clogged. Injection head is fine. That leaves the roller head. Are these in need of replacement from time to time? I have not done that, and my Stenner is probably 2+ years old.
Stenner pump stops moving fluid...

While the roller assembly can lose spring tension after a while, it usually lasts many years. If yours is only a couple years old I would inspect it carefully to see if it's the problem. There's a couple of graphics in the manual on how the pinch point between the roller and tube should look when it's correct.
How long ago did you replace the tube?
I'd suspect it more than the rollers.
Also, a very tiny leak on the suction side of the pump will prevent it from drawing liquid.

Problem solved...after eliminating the pump itself as an issue (using a new little piece of suction line inserted into a jar of water), i replaced the suction line into the tank. When I removed the old one, the pinch point where the weight/anchor grips the tubing was brittle and snapped. Once i replaced the suction tube (which was 2.5 years old), the pump was moving bleach again. Thanks for the help!
