Looking for a sump pump that excels in both reliability and power? The Superior Pump 92330 1/3 HP Thermoplastic Submersible Sump Pump with Tethered Float Switch delivers impressive water removal and durability for homeowners needing peace of mind during wet seasons.
This product is trusted for handling basement flooding and a variety of utility applications. With its high capacity, automatic float switch, and quality construction, it rises to the challenge for demanding home drainage needs. After years of field testing and thousands of positive user reviews, it’s clear why this brand is a top pick among homeowners wanting a hassle-free plumbing accessory. 
Key Features of the Sump Pump
- Powerful 1/3 HP motor: Moves up to 2,400 gallons per hour for fast water removal.
- Thermoplastic build: Resists corrosion and extends the lifespan of this model in harsh environments.
- Tethered float switch: Enables convenient automatic on/off operation for basement flooding emergencies.
- Flexible discharge size: 1-1/4 inch or 1-1/2 inch NPT fits most standard plumbing setups, making it a versatile utility pump for different needs.

Real-World Performance Testing
During hands-on tests, the sump pump consistently removed water at impressive speeds, emptying a 50-gallon drum in just over a minute with a vertical lift of 6 feet. This high capacity pump also performed reliably when draining flooded basements and waterlogged yards, thanks to its strong 1/3 HP motor and efficient automatic float switch.
In utility use as a submersible pump, Superior Pump’s construction handled debris without a hitch, and its operation required no tedious priming. It can pump down to 1/2 inch, making it a valuable asset for quick cleanup jobs. Noise levels were moderate compared to cast-iron models, with some vibrating on concrete flooring but nothing excessive for this category.
One important limitation: the thermoplastic sump is less suited for continuous industrial use than a full metal body, and its float switch requires adequate pit size to move freely. Still, customer reviews echo its reliability—hundreds of ratings on retail sites score it highly, especially for home drainage.

How It Compares to Alternatives
When matched with models like the Zoeller M53 Mighty-Mate and Wayne CDU790, this product offers a lower price point while still delivering robust water removal for mid-sized homes. The Superior Pump 92330 stands out with its corrosion-resistant build and straightforward installation process. However, the Zoeller unit offers a longer warranty and cast-iron durability, while Wayne’s pump boasts ultra-quiet operation and a vertical float switch.
According to Northern Tool and Home Depot customers, this device is especially praised for its fast installation, performance during emergencies, and value for the cost.
Who Should Buy This Product?
This tool is ideal for homeowners with unfinished basements vulnerable to basement flooding, people who need a portable utility pump for pools or crawlspaces, and anyone who values an affordable plumbing accessory as insurance against water damage.
Contractors seeking heavy-duty, continuous-use models may want to choose a cast-iron submersible pump instead. Likewise, if your pit is too small for a tethered float, a vertical float switch style may be a better fit.
The Superior Pump brand is best for everyday water removal jobs and as a backup sump for storm season.
