1. Zoeller M53 Mighty-mate Submersible Sump Pump Review

Zoeller M53 Review
Check Price on Amazon

Zoeller M53 Mighty-mate is one of the Zoeller’s top-selling sump pumps. This little beast is packed up with many amusing features that add value for the customers.

Heavy-duty cast-iron is used as the material for the base. It helps the pump to dissipate heat evenly throughout the whole pump. Thus you can get rid of the red or hot spots that can cause damage. Also, the non-corrosive elements help to protect the pump against corrosion and rust.

As an extra benefit, the pump features a powdered epoxy layer to prevent any kind of water damage. It remains fit inside the water and looks more aesthetic. Of course, functionality is more important when it comes to sump pumps. But the design of sump pumps actually plays a role in their effectiveness too.

Moreover, the exterior of the pump is really solid and durable. The pump features stainless-steel shafts, a carrying handle, and a 9’ long safe power cord. Thanks to its engineering, the pump is safer to use and eliminates the risk of electric shock.

And how can we not talk about the performance? The maximum flow rate of this pump is 163 LPM. For a 1/3 HP powered motor, the flow rate is indeed satisfactory. It can handle continuous water inflow into the sump pit without getting tired. It also offers a polypropylene switch to avoid accidents.

Well, now you know the reason why the mighty-mate has won the hearts of thousands of plumbers and owners all over the world.


  • The pump is strong enough to fight against corrosion or rust for a long time.
  • It comes with a 3-year manufacturer’s warranty.
  • It is pre-assembled and easy to set up.
  • It can easily suit an average household with a low water table.
  • The price is also within an affordable range.
  • The maximum speed can rise up to 1550 RPM. For a 1/3 HP motor, this flow rate is beyond average.


  • Being a 1/3 HP sump pump, it might not be sufficient for handling rough water emergencies.
  • Comparing to our other sump pumps in this article, it has a shorter life-span.

Here is a piece of advice. You should not neglect a quality check valve. It prevents the water in the pipe from switching direction and falls back into the sump pit. Besides, check-valves also help the pump to operate quietly and give you peace of mind.

2. Zoeller M98 Flow-mate Submersible Sump Pump Review

If you are looking for something more powerful and sturdy than the Zoeller m53, then Zoeller m98 flow-mate sump pump is what you need. It is a ½ HP sump pump with a 30 GPM extra flow rate than the mighty-mate pump.

The best feature of this pump will be its exceptional performance. It can pump 4320 GPH at 0′ height, 3660 GPH at 10′, and 2700 GPH at 15′ head. Head refers to the vertical length of the discharge pipe that the water has to go through.

Besides, the sump pump offers some other useful features like a 15’ long power cord. Neoprene square ring seals are also used to prevent any kind of leakage. As long as all the moisture and air remains inside the pit, your basement is safe. Neoprene seals are different than rubber seals. These seals are airtight with the ability to resist weather and flame.

Another great thing about this pump is its ability to handle various dewatering tasks easily. You can use it in your sewage tank, septic tank, STEP system, and low-pressure pipe systems too. Talk about multi-tasking!

The thermal protection system saves the pump from severe damage during continuous operation. When the pump starts to overheat due to the non-stop rotation of the impeller, these sensors can detect the rise in temperature precisely. And before the overheating can cause trouble, the pump halts all the operation to cool down.

Though it has every feature to bring you comfort, due to some premature failures and complaints we can’t place it on our top-pick.


  • No sheet metal parts are used to prevent corrosion or rusting effectively.
  • Airtight seals make sure that nothing can leak from the chambers.
  • The construction material is durable and strong (cast-iron class 25-30).
  • The pump has to pass a thorough pressure test before leaving the factory.
  • The flow rate of 4320 GPH is really powerful.
  • It also comes with a satisfactory manufacturer’s warranty.


  • Many customers have complained that the switch wouldn’t turn on due to badly designed rubber boot coverings.
  • Though the pump is quite powerful, the performance is not steady.

Here is a quick tip. It is essential to install a battery backup system to move water even during a power outage. If you live in a low-lying area with a high water table, power outage during rainstorms can be your biggest nightmare.

3. Zoeller M57 Submersible Sump Pump Review

People who only seek premium services, have to spend some extra cash. On the other hand, customers with a tight budget often seem to neglect quality and end up with a cheap box store sump pump that is up for no good.

Luckily, Zoeller has designed the m57 model so that customers with a low budget can feel a sense of quality in the basic components of this sump pump. You can say you don’t have to compromise the durability and reliability of a cheap price tag anymore.

The pump is built to last with a cast-iron body and epoxy powdered outer layer for extra security. The pump can bear thermal shocks without showing any kind of deformation. That’s a great quality during times when the pump needs to deal with hot liquid.

Also, a buoyant float switch is included to trigger the pump and start the operation. The switch simply floats in the water and keeps rising until it reaches a pre-determined level. As soon as the exact level is crossed, the switch sends a signal to the main pump and the impeller starts to rotate.

Moreover, thermal protection, long power cord, effective no-screen impeller, etc. are some other features of this pump.

For such an average price, this Zoeller m57 is really the best in the whole market. Cost-effectiveness, durability, and power, all these factors combine together and make this pump the perfect water solution to your crawlspace.


  • It is indeed a compact pump that only requires little maintenance from time to time.
  • Powerful pump that moves water in the sump pit within 10 seconds.
  • You can’t hear any disturbing sounds or vibrations from the pump.
  • Solid construction that can handle the heavy inflow of water.
  • It includes an effective float switch which is less prone to failure.
  • You can expect 8 to 16 years of life-span with proper care.


  • 1/3 HP powered pump may not be able to manage huge flooding in the sump pit.
  • Customers have complaints regarding crappy float switches.

Here is a pro tip. You should opt for a pump that is suitable for the water level for your basement. Zoeller provides flow rate charts for every model. If your house encounters frequent water emergencies, go for a more powerful sump pump.

Since submersible sump pumps are difficult to remove from the sump basin, taking time to look for the right one is a wise idea.

Final Verdict

Since you have gone through the whole article, selecting the right sump pump for your home might have become easier. But it’s okay to still being a little confused. Buying a sump pump is a long-time investment. And if you are a first-time buyer, then the selection process can be more overwhelming.

That’s why we have given our final verdict regarding all 4 pumps. Have a look.

The m53 model is an average one with the basic elements at a cheaper price. If we compare between the m53 and the m98, the m98 is surely more sturdy and powerful. It has a 1/2HP motor while the m53 has a 1/3HP motor.

Plus the construction material of m98 is fully cast-iron while the m53 model only uses cast-iron in the base. So, if you want more power and effectiveness, go for the m98 one.

But here is a thing the m98 sump pump can be really risky sometimes. That’s why, for people who want more reliability, the m53 model is a better option.

Now, the m57 premium service sump pump is good at everything. It is slightly better than the previously mentioned pumps. It is stronger, powerful, and shows high-quality design. But the price will be higher to get such services. If your house encounters heavy water inflow, it will be a great pick.

And last but not the least, the m63 submersible sump pump. It is a different category sump pump with more sophisticated features. No doubt it is the most expensive one among all 4 pumps here. So, if you are on a low budget, we won’t recommend this to you.

Hope you benefited from our Zoeller sump pump reviews.
