Zoeller M53 Sump Pump Review

#

A sump pump comes in handy when your basement is prone to flooding and dumpiness. However, not every pump out there will keep your basement in good condition. Investing in a reliable, powerful, and effective pump is paramount.

The Zoeller M53 is a highly rated pump among professional contractors and plumbers.  The pump boasts of impressive capabilities, design, and construction. These features stand the test of reliability and durability which explains why it is the most recommended pump.

Key Features of Zoeller M53

Before purchasing a pump, it is crucial to check the details of the design and features. No matter how well the pump is rated, do not get carried away by the positive reviews. This unit comes with impressive internal and external features that include:

  • Design

The pump weighs 21.0 pounds and it is 7.8 inches long, 10.5 inches in width, and 10.5 wide. It features heavy cast iron construction which makes it very effective in handling heavy water flow. With this construction, you are assured that your basement will remain dry since it will comfortably handle massive pressure.

The greatest challenge with most sump pumps is corrosion since they operate in water. Zoeller takes care of this by utilizing a cast iron coat. This ensures it does not rust or corrode with time. The pump is also designed to dissipate heat efficiently so that internal parts do not get damaged. Since the internal parts are often very delicate, effective heat dissipation ensures they last long.

  • The impeller

The Zoeller M53 features robust impellers that can handle solids up to 12mm. This ability eliminates the chances of clogging with impurities especially if your sump pit contains solid debris. It also ensures the pumping remains consistent.

The impeller also features grooves that ensure the pump draws water quickly and effectively under high pressure. The M53 is also versatile, so you can either use a cast iron or plastic impeller. Since the pump has powerful suction, you are assured of optimal performance with either of the impellers.

  • The switch

One of the impressive features that the pump has is the automatic switch assembly. The switch enables the pump to switch on/off automatically. You do not have to walk to the basement to switch the motor on every time the water level rises. Pretty convenient, right?

  • Safety features

This sump pump also has a switch guard that ensures free and safe operation. The switch is external which ensures you can easily access and replace. It is easy to replace therefore you do not have to worry about fixing a new guard when there is a need to.

  • The Motor

A motor is the heart of every sump pump. No matter how good the design or features are, if the motor is not powerful enough, you will end up with an ineffective pump. The Zoeller M53 features 1/3 HP motor that operates at a speed of 1550 RPM. With this whopping horsepower, the pump bullies its competitors. It is rated as the most powerful motor among sump pumps by the experts.

The motor also features an overheating switch that protects the motor and the delicate internal parts from excess heat.

  • External features

The Zoeller M53 has a non-slip handle that is made of stainless steel. The handle makes it very easy to move it around the basement. It also features a power cord that is 9ft in length. The cord is strong and it is designed to be durable. You will also like the fact the pump has a 1½ inch discharge that is compatible with other PVC standards. The discharge is designed to pass ½ inch spherical solids at a given time.

  • Installation

You do not have to pay the plumber to install the pump. Even though I had never installed a pump before, I found the installation of this sump pump to be easy and very straight forward. The installation instructions are diagrammatically explained in the instruction in a clear manner that is very easy to understand.

Ensure that the float and the level of the pump are not in contact with any substance for durability. Also, it is essential to get a new check valve for the pump.

PROS:

  • The pump is quiet
  • Excellent reliability and durability
  • Easy to install and maintain
