Question by: Hubert S on Jul 29, 2025, 4:44 PM
pump keeps stalling out mid-cycle on my current setup -- does this ARO model have anything built in to keep it from doing that?
Answer by: Customer Support on Jul 31, 2025, 8:08 AM
One of the key features on this pump is the patented "Unbalanced" air valve design, which is specifically built to make sure the pump always resumes pumping action when called upon. Stalling mid-cycle is exactly the kind of problem that feature addresses. So if your current unit is getting hung up and not restarting on its own, this would be a meaningful upgrade in that regard.
