Build Quality

All sump pumps come into contact with water, so their endurance is a significant issue. The entire body of the Zoeller  M63 premium series sump pump comes with cast iron and powdered epoxy coating. These materials prevent corrosion. It runs efficiently without any delay while discharging water.

Besides, it does not use any sheet metal, reducing the chance of rusting and breakage. The float switches use Viton, which is a combination of synthetic rubber and fluoropolymer. It is chemical-resistant. Therefore, the durability of this unit is undoubtedly admirable.


Zoeller M63 comes with a unique design and user-friendly features, which makes maintenance super easy. There is a green LED in the plug to make sure the sump pump has an electrical connection. It has a beautiful color of epoxy coating that lasts even after remaining in the water for an extended period. With these contrasts of coat and color, this unit efficiently dissipates heat in the water to ensure the maximum lifespan of the motor.

Besides, there is a handle, switch guard, and other arms and screws, which use stainless steel. So, it stays shiny from the outside and robust from the inside.


It is challenging to beat Zoeller, especially when it comes to power. This product comprises a powerful 3/10 HP motor that pumps out a large volume of water from your basement. The sump pump runs smoothly and removes water, starting at 0-feet to 19.25-feet. Although the amount of discharge varies at different heights, however, the flow rate is remarkable.

Flow Rate

Flow rate determines the amount of water a pump can move from one place to another. Thus, it’s essential to have a reasonable rate of water flow- the number should depend on the water your basement takes in during stormy weather. This unit offers a powerful 3/10 HP motor that can successfully remove around 2580 gallons of water per hour. The rate of flow remains maximum at 0-feet height.

If the height keeps increasing, the discharge rate slightly changes. The discharge rate drops at a height of 10-feet, removing around 2040 GPH water. Accordingly, it pumps out 1140 GPH water at 15-feet and stops responding at 20-feet. Overall, this unit can accumulate water at a maximum height of 19.25 feet that is exceptionally high compared to any other random sump pump.

NPT Discharge Capacity

The NPT discharge capacity of this submersible sump pump is 1-1/2 inch that is suitable for both commercial and residential usages. The hosepipe is ideal for all types of standard PVC pipes. So, this product is capable of draining 1/2 inch of spherical waste or debris without any hindrance.


There is a cast-iron-based impeller included in this sump pump. It ensures the maximum stream of water and also averts the water clogging and air trapping.

Power Cord

This product also offers a power cord that is around 10 ft long. It is essential in terms of safety in the flooded basement. So, it helps the smooth movement of air and prevents electrical accidents by remaining dry. Also, it has a LED light at the end, which lets the user know whether it has access to electricity or not.


Maneuverability is also significant, and with respect to that, this product includes a stainless-steel handle. It is durable and allows a firm grip. Even though it is a bit huge, you can still shift it from one place to another very quickly.

Float Operated System

Those who are using a sump pump with a float operating system should consider themselves lucky. So, if you are thinking of buying this submersible pump, then you are also one of those lucky users. Floating switches play a vital role in detecting the flooding level in the tank or mainly in the basement of your house. It is automated, which means you are free of monitoring the pump. The float switch automatically activates when the water reaches a certain level. It removes all the water when the float rises to a fixed point.

Again, it deactivates by itself when the pump completes water discharging.

Easy Installation & Maintenance

The sump pump is effortless to install; all you need to do is follow the instruction manual carefully. The best part is the manual book, which is very clear and straightforward, so you do not have to be an expert to assemble this pump. However, if you are not able to cope with larger fittings, then it’s better to contact a plumber to avoid any water leakage.

Moreover, this unit also requires maintenance for an extended lifespan. It’d be best if you keep track of the pump’s condition once in a while. Check-in with it, and see if you observe any anomaly, look for information, and take actions accordingly.


This product offers a massive five-year warranty. As we’ve said before, Zoeller sump pumps are literally Ogre-like when it comes to durability. And the warranty is a verification of that longevity. Also, while going through several reviews of Zoeller M63 Sump Pump and from our personal experience, we have found that this product lasts way more than five years.
