Scroll down the page and see what 14 customers said about: how long do Zoeller sump pumps last?

Zoeller submersible sump pumps are designed to work tirelessly to keep your basement or crawl space dry. However, their lifespan is an important thing to consider because the actual lifespan can vary depending on several factors.

These submersible sump pumps typically have a lifespan of around 7 to 10 years or complete an average of ~100,000 cycles. Yet, there can be exceptions where Zoeller sump pumps have lasted longer. Various factors can affect a Zoeller sump pump’s lifespan, including usage, maintenance, and conditions.

Today, we’ll discuss some expert tips on maintaining your pump to ensure it lasts even longer. So, let’s get started.

How to Maintain Zoeller Sump Pumps to Last a Long Time?

To ensure your Zoeller sump pump lasts longer, there are several key maintenance tasks you should regularly perform.

• Cleaning the pump regularly
• Examine the check valve periodically
• Regularly inspect the operation of the float ball and switch
• Regularly clean the impeller
• Inspect the power supply
• Check for leaks
• Replace damaged or worn parts immediately
• Clean or replace the discharge pipe
• Maintain the sump pit cover
• Maintain proper battery backup

1. Cleaning the Pump Regularly

If you want your Zoeller sump pump to last longer, regularly clean it to prevent clogs and maintain efficient operation. Start by turning off the power to the submersible sump pump before performing maintenance. If possible, remove the sump pump from the pit to have better access.

2. Examine the Check Valve Periodically

A check valve prevents backflow, which can cause damage to your pump and affect its overall efficiency. Check your Zoeller sump pump’s check valve periodically to ensure it’s working right and only letting water flow in one direction.

It is advisable to have a clear view check valve  to be able to see its operation. The Zoeller company does not have such a check valve, so you may want to replace your current Zoeller check valve.

You would have to remove it to visually check the operation of a Zoeller check valve. Ensure it moves freely and without resistance.

Otherwise, listen for any unusual sounds during operation, as this could indicate a faulty check valve. Look in the sump basin to see if more water than normal flows back into the sump pit.

3. Regularly Inspect and Adjust the Float Switch

The float switch is a critical component that triggers the pump to turn on and off, ensuring proper functioning. Begin by inspecting the float switch for any debris or obstructions hindering its movement. Clear away any debris and ensure the switch moves freely.

Next, adjust the Zoeller sump pump float switch periodically to maintain the proper flow rate. This adjustment is necessary to ensure the pump turns on and off at the correct water levels.

4. Regularly Clean the Impeller

Honestly, this should not be a problem because the Zoeller impeeller is designed so that only objects bigger than 1/2 inch diameter would block it.

Water is removed from the pit by the motor impeller, so it’s important to keep it free from obstructions or debris. Over time, dirt, sand, and other particles can accumulate on the impeller, reducing its efficiency and potentially causing the sump pump to malfunction.

To maintain the longevity of your Zoeller sump pump, regularly cleaning the impeller is essential. Disconnect the power to the pump and remove the pump from the sump basin. Be thorough and ensure that all dirt and debris are removed. Once the impeller is clean, reassemble the sump pump and test it to ensure proper functioning.

5. Inspect the Power Supply

Loose connections can lead to power interruptions or fluctuations, causing the pump to malfunction or fail altogether. Also, damaged electrical connections can pose a safety hazard, increasing the risk of electrical shock or fire.

6. Check for Leaks

Leaks within the motor housing will distroy the motor and the pump will need to be replaced.

Discharge pipe leaks can indicate a problem with the check valve seal or connections, and if left unattended, they can reduce the pump’s efficiency. Regularly checking for leaks is essential to maintaining your Zoeller sump pump and ensuring its longevity.

Look for any signs of water dripping or pooling around the pump basin cover or along the pipe. Also, check the connections between the pump, check valve and discharge pipe.

7. Replace Damaged or Worn Parts Immediately

You can ensure your sump pump lasts longer by promptly replacing damaged or worn parts. During your regular inspection, look for components like the float switch, check valve, or impeller that show signs of damage or wear.

These parts play a crucial role in the pump’s performance and reliability. A damaged float switch, for example, may fail to activate the pump when water levels rise, leaving your basement vulnerable to flooding.

8. Clean or Replace the Discharge Pipe

Discharge pipes transport water away from pumps and your basement or crawl space. Over time, any pipe that extends outside of the house can become clogged with leaves, dirt, or other debris, reducing the flow of water and putting strain on the pump.

To clean the discharge pipe, you can use a garden hose or a pipe-cleaning brush to remove any obstructions. If the buildup is severe or the pipe is damaged, it may be necessary to replace it entirely.

9. Maintain the Sump Pit Cover

Most sump basin covers do not fully seal the sump basin. So, household dirt, toys, and critters can get into the somp basin. Only fully sealed radon type sump basin covers will keep everything out.

A properly fitting cover is essential for preventing debris and odors from escaping into your basement. Start by inspecting the cover for any cracks, breaks, or signs of wear. If you notice any damage, it’s important to repair or replace the cover promptly.

Also, make sure the raydon cover is securely fastened to the sump pit to prevent it from becoming dislodged during pump operation. Cleaning the underside of the cover is crucial to removing accumulated dirt, debris, or mold.

10. Maintain Proper Battery Backup

Most battery backup systems have a controller that monitors the system and will sound an alarm, light up an LED bulb, or notify homeowners via phone text.

However, it’s recommended to test the battery backup system controller on your Zoeller sump pump at least once every three months. This will help ensure that the controller and battery are functioning properly and can provide the necessary power to operate the pump during a power outage.

What shortens the lifespan of a Zoeller sump pump?

Several factors can contribute to the shortened lifespan of a Zoeller sump pump.

One common factor is rust and corrosion. Cast iron and even stainless steel sump pumps can rust. Over time, exposure to water and moisture can cause the pump’s metal components to corrode, leading to decreased efficiency and potential failure.

Clogs can also be detrimental to the lifespan of a sump pump. Debris, dirt, and other materials can accumulate in the pump, obstructing its operation and causing strain on the motor.

Can a Zoeller m53 sump pump last 15 years?

A properly maintained Zoeller M53 sump pump can last 15 years or more. However, expect to replace the float switch at least once during those 15 years. Unlike typical submersible pumps that have a lifespan of five to seven years, the Zoeller M53 pump is designed to withstand constant exposure to water and the risks of corrosion.

This durability is due to its high-quality construction and materials. The Zoeller M53 submersible sump pump is made with corrosion-resistant materials such as cast iron, ensuring its longevity even in harsh conditions.

What is the primary difference between Zoeller M53 and M57 sump pump??

The primary difference between the Zoeller M53 and M57 sump pumps is the material used for their bases and the impeller.

The M53 sump pump has a base and impeller made of thermoplastic, a durable and corrosion-resistant material. On the other hand, the M57 sump pump features a base and impeller made of cast iron.

Cast iron is renowned for its strength and durability, providing a sturdy foundation for the pump. This material is particularly suitable for heavy-duty applications and environments where there may be higher levels of wear and tear.

Extend the Lifespan of Your Zoeller Sump Pump with Proper Maintenance

So, how long do Zoeller sump pumps last? The Zoeller sump pumps are designed to last 7 to 10 years or around 100,000 cycles. Customers say that it is not unusual for them to last 15-30 years.
