Powerful (Utility Pump): Superior Pump 91570
- Very powerful & efficient - ½ HP motor & split capacitor
- Solid and long-lasting - double heavy-duty stainless-steel jacketed shaft seal
- Reliable - CSA certified and UL/CUL listed
- The filter could work better
- The hard plastic feet aren’t conductive to put on a hot tub shell
Superior Pump 91570 sets it apart with its powerful ½ HP motor that can suction up to 3,300 GPH at 0’ depth – nearly twice faster than other models that we have tested.
At 20’ depth, it still works very powerfully with 1,500GPH of flow rate.
Another notable feature is the split capacitor that includes two gears - one for boosting the start-up and one for keeping the operation efficient.
We were also impressed with its solid and closed structure. The double jacketed shaft seal that is made of heavy-duty stainless steel keeps the motor housing from water-absorbing pretty well.
This design is CSA certified and UL/CUL listed, as well as carrying the manufacturer's 3-year warranty.

Easy To Install (Utility Pump): Little Giant 505025
- Come almost completely pre-assembled
- Hard-wearing & able to work in hot tubs - overheat-resistant motor & die-cast aluminum housing with epoxy coating
- A bit pricey
The Little Giant 505025 comes almost completely pre-assembled, so the remaining task for you is little and it is also quick to finish - unlike the two above which only come 50-60% pre-assembled.
Among three picks in this category, it's easy to point out that this is the least powerful.
It can suction water 1,200 GPH, which is more of a device for light-duty tasks.
But we appreciate its quality structure which includes an overheat-resistant motor and a die-cast aluminum housing with epoxy coating. It can work in hot tubs up to 120 degrees F with no issues.

Powerful (Sump Pump): MEDAS 4623 GPH
- Very powerful – feature a 1HP motor

MEDAS 4623 GPH far outperformed the other brands in power. It boasts a 1HP motor - twice stronger than our former pick: the Homdox Sump Pump.
It provides up to 4,623 GPH max flow rate and can pass big solids up to 1" diameter without clogging, allowing for use in both clean and dirty water.
As for the water-suction function, the sump pump can remove water level down to 1mm.
But what we liked the most about this unit is the safety design. It automatically shuts down if failing to pump water or when the water level is under 4.7", and turns on when the water level is above 4.7".
Meanwhile, its motor has thermal overload protection designed for safety when running constantly.

How To Choose The Best Submersible Pool Pump?
This feature shows you how powerful a submersible pool pump is. Its measuring unit is gallons per hour (GPH). A basic rule of thumb is the higher the discharge rate, the faster the pump can run.
When choosing submersible pool pumps, the discharge rate of the tool must be equal to or higher than the required pressure.
For example, a 500GPH pool pump is perfect to tackle a hot tub while a 1,000 to 3,000 GPH model is powerful enough for a large-size pool.
Types Of Pump
There are two main types of submersible pool pumps: sump pumps and utility pumps.
To determine which one is the best for your needs, please take a peek at this table:
Purpose of use
For draining flooded basement
For draining well, emptying clogged sinks, removing standing water, etc.
Fast water-pumping performance
Unable to pump solids, so they’re not suitable for sewage-type applications
Places with infrequent flooding
It is important to pay extra attention to the safety features when choosing them.
Auto-shutoff is the one that any pump must-have.
This feature will automatically turn the tool off when detecting that the water level is under the minimum, which keeps you and the pump safe.

Can I use a submersible pump in a pool?
Yes, you can. Submersible pumps are made to remove excess water from a swimming pool or spas.
How do submersible pool pumps work?
Here is the way a submersible pool pump works: At the place that it is located, the motor pulls water from the side or bottom into the pump. Then, it expels the water through a hose to a predetermined spot (which is usually away from the spot being pumped).
Can I be in the pool with a submersible pump?
No, you can’t.
It is risky to be in the pool with a submersible pump. Accidents might happen, so wait until the tool finishes its job and is removed from the pool.
Can you leave a submersible pump plugged in?
Yes, you can.
All submersible pumps are built to not turn on until the water level is above 1-1/4 inches.
How long can a submersible pump run continuously?
A low-quality submersible pump can run constantly for 6-18 hours while a high-quality one can last 20 to 24 hours. After that, you should let it take a break.
Can I clean the bottom of my pool without a pump?
No, you can’t.
A pump is a must when it comes to cleaning the bottom of a swimming pool. But there are ways to keep the pool water clean for longer, such as agitate and circulate, prevent algae, sanitize by using chlorine and frequently remove debris.
How do I know if my submersible pump is bad?
There are some noticeable signs to let you know if your submersible pump is bad. The easiest way is to use your ohmmeter. For more detailed guides, please follow this tutorial video: https://www.youtube.com/watch?v=SIEnOZRybds
Can a pool pump hurt me?
Yes, it can.
The power output of a pool pump might hurt or cause life-threatening injury. If you unwittingly cover the suction point of the pump with any of your body parts, it might disembowel, drown, or trap you.
How long does a submersible pool pump last?
A submersible pool pump averagely lasts 8 to 15 years.
At what depth should a submersible pump be installed?
