What Should You Look For When Choosing the Best Zoeller Sump Pump?

What Should You Look For When Choosing the Best Zoeller Sump Pump

Purchasing a sump pump is no easy task. Hordes of data to parse through and the potential for an expensive misstep makes it critical to do your due diligence before splashing out. So don’t let yourself be taken in by slick sales pitches or flashy features.

Ensure that any model you settle on ticks all the boxes of what’s needed. Here are some key factors to keep in mind:

ONE: Determine the Size of the Sump Pit

It is essential to ascertain the dimensions of your sump pit before choosing a sump pump to ensure its compatibility. The sump pit’s size must smoothly accommodate the pump without causing interference or water flow restrictions.

To determine the sump pit’s size, measure its diameter and depth. Standard sumps pits are typically 18 to 24 inches in diameter and 24 to 36 inches deep. Zoeller pumps offer various models with different dimensions that cater to these standard sump pit sizes.

TWO: Look For a Pump With Adequate Horsepower

A sump pump’s horsepower (HP) directly correlates to its pumping capacity, indicating the pump’s strength in removing water from your basement. Consider your basement’s drainage requirements, such as the volume of water and the lift height (how far the water has to travel).

For example, you might want a model with more horsepower if you live in an area with frequent heavy rains or melting snow. So that it can keep up with significant amounts of incoming water.

THRE: Opt for Pumps with Backup Protection

A backup system is a valuable feature that helps to protect your property against water damage in the event of power outages or primary pump failure. Some sump pumps offer various options, including battery backup- and water-powered.

Battery backup sump pumps kick in when electricity is lost, ensuring continuous water removal during storms or other power outages. Water-powered backup pumps use the force of running water to operate, making them an environmentally friendly and longer-lasting option.

Consider investing in a backup generator as an additional safety measure, especially if your area is prone to severe storms or extended power outages.

FOUR: Consider the Switch Type

Consider the Switch Type

The switch on a sump pump controls its activation and deactivation in response to water levels. As for the switch types, sump pumps come with two primary switch types: float switches and pressure sensor switches.

Float switches are mechanical devices that activate the pump when a buoyant float rises with the water level. These switches can be tethered, vertical, or electronic. Float switches that are tethered or vertical work mechanically, while electronic float switches use microswitches.

Pressure sensor switches, also known as diaphragm switches, activate the pump when water pressure increases. These switches tend to be more sensitive compared to float switches but might require more regular maintenance.

Consider your preferences for switch reliability, precision, and maintenance requirements when choosing a sump pump for your home.

FIVE: Be Aware of the Flow Rate

When choosing a sump pump, the flow rate (measured in gallons per minute or GPM) is crucial since it shows how well the pump can remove water. To identify the appropriate flow rate for your needs, assess your basement’s water inflow tendencies, such as the frequency and severity of floods.

A pump with a 30-40 GPM flow rate may be sufficient for homes with minor flooding issues. However, if your property experiences heavy flooding or has a high water table, you may need a pump with a flow rate of 50 GPM or more.

SIX: Look For Easy Maintenance 

Regular maintenance is key in keeping your pump running smoothly and helping it last longer without needing replacement parts or repairs down the line. Some pumps require frequent cleaning and/or replacement parts which can be costly over time (not just monetarily but also in terms of time).

With Zoeller models, regular maintenance only takes a few minutes, and filters are easy to replace without special tools. Also, some sump pumps have alarms that let you know if there’s a problem so you can fix it quickly.

So choose a model that is easy to maintain and has all the necessary features.

SEVEN: Check for Durability

Durability is essential when selecting a sump pump since this device will be exposed to water consistently (which causes rusting over time). Pumps made from corrosion-resistant materials like stainless steel or cast iron will likely last long.

Many sump pumps are designed to last under tough conditions (like frequent high temperatures). That way, they don’t have to do expensive repairs down the line due to corrosion or moisture buildup.

What Are the Most Common Sump Pump Problems?

What Are the Most Common Sump Pump Problems

Your basement may be nicely dry, but the cost can reach catastrophic levels when sump pumps fail. Avoid unnecessary headaches by being aware of common issues that could disrupt this vital home infrastructure.

Problems with sump pumps include:

Clogged or Obstructed Intake Screen: An essential part of the sump pump is its intake screen, which prevents debris from choking your system. Over time, this screen can get clogged, affecting your pump’s ability to function.

Stuck or Faulty Float Switch: The float switch activates the sump pump when water levels rise. If this switch becomes stuck in either an “on” or “off” position, it won’t be able to respond effectively to changes in water level.

Power Failure: A power outage means your sump pump shuts down, putting your basement at risk for flooding. Solution? Battery backup sump pumps. With a battery backup pump, your sump pump keeps working even when the power goes out.

Overwhelmed Pump: Sometimes, your pump becomes overwhelmed, especially during heavy rains, leading to those dreaded waterlogged basements. Getting too much water in the sump pit too fast can overwhelm the sump pump.

Clogged or Frozen Discharge Pipe: The discharge pipe that carries water away from the sump pump can become clogged with debris or frozen in cold weather. That can’t stop water from coming out.

Pump Motor Failure: Like any motor, the sump pump is not immune to failure over time. Although the motor’s life may vary depending on the model, you should plan to replace it eventually.

Incorrect Installation: Incorrect installation could be the root cause of many sump pump problems. Hiring a professional for installation is highly recommended to avoid structural issues, hydraulic overloads, or just poor performance altogether.

Is It Okay to Leave a Sump Pump Running Continuously?

It’s not ideal for a sump pump to run all the time. A properly functioning sump pump should only run when necessary, typically during heavy rainfall or when water levels in the sump pit rise.

A constantly running sump pump could be a problem with the pump’s float switch, which controls its activation, or with the drain system. Also, the continual operation can wear down the pump prematurely, making it less efficient or even breaking it.

Regular maintenance and inspection of your sump pump system. For example, making sure the float switch works, cleaning the sump pit, and ensuring proper water drainage can extend the life of your sump pump.

What Are the Signs That a Sump Pump is Going Bad?

What Are the Signs That a Sump Pump is Going Bad

Knowing the signs of a failing sump pump can help you plan for repairs or replacements before disaster strikes. Keep an eye out for these warning signs:

1. Excessive Vibrations: 

One of the first signs that something may be wrong with your sump pump is if it vibrates excessively or shakes when in operation. This is often due to a damaged motor or impeller, which may have become unbalanced after wear and tear or accidentally sucking up debris.

Over time, these vibrations can cause damage to other components and decrease the overall efficiency of your sump pump.

2. Strange Noises:

Unusual sounds coming from your sump pump can indicate a failing motor or impeller. Grinding, squeaking, or rattling noises are abnormal and could mean internal components are damaged or worn out.

If you hear these types of sounds, it’s essential to have a professional assess the situation as soon as possible to prevent further damage and potential water infiltration.

3. Unpleasant Odors

A foul smell emitting from your sump pump may indicate something is amiss. There are a few possible reasons for this unpleasant odor, such as an overheating pump, mold, or mildew.

Overheating can occur if the pump is working too hard, and this can cause damage to internal components. On the other hand, mold and mildew can form if water is not adequately pumped out of the sump basin, leading to stagnant water and potential health risks.

4. Constant Cycling

A sump pump constantly cycling on and off could signal a problem with the pump itself or the amount of water it’s handling. An errant float switch or an incorrectly sized pump can cause this or even a malfunctioning float switch.

A professional can help determine if the pump needs replacing or replacing.

5. Visible Damage

It probably needs fixing if your sump pump has visible damage, like cracks or dents. These issues may not directly impact the pump’s performance, but they can lead to problems down the line, such as water leaks or electrical shorts.

In some cases, the visible damage could indicate more severe internal issues.
