2025 Sump Pump Buying Guide

If you live in a flood-prone area in Missouri, a sump pump isn’t just some upsell from your plumber—it’s an absolute necessity.

Imagine that during the next heavy rain, the ground around your home becomes saturated, and before you know it, water starts pooling in your basement or crawl space. It might start small—a damp corner, a trickle here or there—but left unchecked, that water can lead to big problems.

We’re talking mold, mildew, and structural damage that can compromise your home’s safety and your family’s health.

A sump pump is your first line of defense against these issues. It’s designed to remove excess water from your basement or crawlspace, keeping it dry and protected even when the weather outside is anything but friendly.

Developed by the sump pump experts at Tony LaMartina Plumbing, this guide will walk you through everything you need to know about sump pumps, from types and features to maintenance tips and installation considerations.

Whether you’re a first-time homeowner wanting to protect your property or a long-term resident needing to upgrade your existing sump pump system, understanding how sump pumps work and how to choose the right one for your needs is essential.

What Is a Sump Pump and How Does It Work?

A sump pump is a mechanical device designed to remove water accumulating around a home and is typically installed in a basement or crawl space. The pump activates when water levels rise, directing the water away from your property to prevent flooding and water damage.

Here’s a breakdown of how a sump pump operates:

1. Collection of Water in the Sump Pit
   Water from around your home’s foundation naturally flows into a designated pit, called a sump pit or sump basin, which is installed below ground level in your basement or crawlspace. This pit acts as a reservoir to collect water from rain, melting snow, or groundwater that seeps into the area.
   
   
2. Activation of the Sump Pump
   Most sump pumps are equipped with a float switch, which works similarly to a float in a toilet tank. As the water level in the sump pit rises, the float moves upward. When the water reaches a certain level, the float triggers the pump to turn on.
   
   
3. Pumping Water Out
   Once activated, the sump pump draws water out of the pit and channels it away from your home through a discharge pipe. The discharge pipe directs the water to a safe location, such as a storm drain, dry well, or an area far from your foundation, where it won’t cause problems.
   
   
4. Automatic Shut-Off
   After the water level in the pit drops back down, the float lowers, and the pump shuts off. This process ensures the sump pump only runs when it’s needed, conserving energy and preventing unnecessary wear.

With regular maintenance and proper installation, a sump pump is a reliable tool to keep your home dry and protected from water damage.

Types of Sump Pumps

When selecting a sump pump, it’s important to understand the two main types available:

1. Pedestal Sump Pumps

Design: The motor is mounted above the sump basin, keeping it out of the water.

Pros: Affordable, easy to maintain, and long-lasting since the motor stays dry.

Cons: Noisier and takes up more space compared to submersible models.

2. Submersible Sump Pumps

Design: Fully submerged in the sump basin, with the motor sealed to prevent water damage.

Pros: Quiet operation and more efficient at handling large volumes of water.

Cons: Higher upfront cost and more challenging to repair.

Additional Sump Pump Options

• Battery Backup Sump Pumps: Ideal for areas also prone to power outages, these pumps activate when the primary pump fails.

• Water-Powered Backup Pumps: Use municipal water pressure to operate, making them a reliable choice for homes connected to city water systems.

What Type of Sump Pump is Right for My Home?

To select the best sump pump for your needs, consider the following factors:

• Pump Capacity: Determine the pump’s capacity in gallons per minute (GPM) or gallons per hour (GPH). A higher capacity is essential for areas with heavy rainfall or frequent flooding.

• Power Source: Ensure your sump pump has a reliable power source. Homes in storm-prone areas may benefit from battery backups or generator compatibility.

• Installation Site: To ensure a proper fit, consider the size of your sump basin and the pump’s dimensions. Submersible pumps require a deeper basin, while pedestal models need adequate clearance above it.

• Cost: While budget-friendly options are available, investing in a high-quality pump can save you money on repairs and replacements in the long run.

Key Features of Sump Pumps to Consider

The latest sump pump models come equipped with innovative features that enhance performance and reliability. These features include:

1. Smart Technology

Many sump pumps now integrate with smart home systems, allowing you to monitor performance, water levels, and power status through a smartphone app.

2. Energy Efficiency

Energy-efficient models reduce power consumption without compromising performance, helping you save on utility bills.

3. Durable Materials

Look for pumps made from corrosion-resistant materials like cast iron or thermoplastic for long-lasting performance.

4. High-Capacity Motors

Modern sump pumps offer powerful motors capable of handling higher gallons-per-hour (GPH) ratings to combat heavy rainfall and flooding.

5. Quiet Operation

Improved designs and sound-dampening materials ensure quieter operation, making them suitable for finished basements.

Professional Sump Pump Installation

Proper sump pump installation is key to its performance. Professional technicians assess your home’s drainage needs and select the right pump for the job. They ensure the system is positioned correctly, the discharge lines are clear and directed away from your foundation, and the pump is primed for reliable operation.

A Tony LaMartina Plumbing inspection involves cleaning the pump, testing its responsiveness, and checking for wear on critical components like the float switch, impeller, and check valve.

A sump pump inspection helps extend the pump’s lifespan and prevent unexpected failures by identifying potential issues early.

How Much Does It Cost to Install a Sump Pump?

The cost of installing a sump pump can vary depending on factors like the type of pump you choose, the complexity of the installation, and your home’s unique needs.

Angi’s, a platform that connects homeowners with trusted local professionals for a wide range of home services, collected data nationwide to estimate the average cost of a sump pump installation or replacement.

On average, homeowners across the nation spend between $1,200 and $1,500 for a professional sump pump installation, while a repair or replacement can fall within $250-$700. 

Here’s what impacts the final price:

• Type of Sump Pump: Prices vary depending on the type of sump pump. Submersible sump pumps are often more expensive.
• Labor Costs: Different areas across the nation and even across Missouri charge differently for labor.
• Additional Features and Costs: Battery backups or installing a drainage system can add to the overall cost. Permitting can also add to the final expense.

Installing a sump pump may seem like a significant upfront expense, but it’s a small price to pay to protect your home from costly water damage, mold remediation, and foundation repairs.

Sump Pump Maintenance Tips for Longevity

Proper maintenance ensures your sump pump operates reliably for years to come. Follow these tips to keep your system in top shape:

• Inspect Regularly: Check the pump and basin for debris, rust, or wear every three to six months.
• Clean the Basin: Remove sediment and debris that can clog the pump.
• Test the Pump: Pour water into the basin periodically to verify that the pump activates and drains correctly.
• Check the Discharge Line: Ensure the discharge pipe is free of obstructions and directs water away from your home.
• Monitor Backup Systems: Test battery or water-powered backups to confirm they’re functional.
• Professional Maintenance: A maintenance visit from Tony LaMartina Plumbing can take the above tasks off your to-do list and ensure everything is done as effectively and efficiently as possible.
