What experts liked
Offers similar water removing action as higher-priced models made possible by its 1/3 HP motor.
- BestReviews
One striking characteristic of this best submersible sump pump is how the heat generated from the motor is cast away promptly, which actually proved to be a contributing factor in providing maximum efficiency and making the unit less susceptible to damage.
- Jen Reviews
The adapter for the sump pump is the style of a garden hose allowing the adapter to be removable. By having an adapter that can be removed allows the sump pump to be used for several different applications.
- Best Consumer Reviews
This small sump pump is one of the cheapest models we have looked at in our guide. Cheaper pumps do exist, but they don’t have anywhere near as impressive a rating as this pump has.
- Water Filter Answers
The Superior Pump 91330 is a well-designed pump that can move a considerable volume of water within a short time. It can move up to 40 gallons of water per minute.
- 11 Must
What experts didn't like
Gets a little sluggish with some task that require quick removal of excessive water. Doesn't have automatic shutoff.
- BestReviews
The motor is thermally protected with a split capacitor hence it has fewer chances of breaking down.
