Home >> Why You Need a Sump Pump in Flood Prone Areas

March 22, 2025

Flooding can be a homeowner’s worst nightmare. The damage it causes can be devastating and the costs to repair that damage can be significant. If you reside in a flood-prone location, taking proactive measures to protect your house is not just a suggestion; it’s a requirement. One of the most effective ways to do so is by installing a sump pump. If your house is located in the Denton County area, it would be in your best interest to contact Haltex Plumbing to install a sump pump to give you peace of mind during heavy rains. In this blog post we break down why it’s important to have a sump pump, how it works, and what you need to know to protect your property.

What is a sump pump?

To begin, a sump pump is a device installed in a small excavation, known as a sump pit, typically located in the lowest part of a residence, such as a basement or crawl space. When water accumulates in this pit, the pump activates and expels it through a discharge pipe, directing it away from the structure. This mechanism acts as a reliable defense against water intrusion, preventing it from compromising walls, flooring, or the foundation.

How does a sump pump work?

At its core, a sump pump system has three main parts:

• The sump pit: This is a hole (usually 18–24 inches deep and 18–24 inches wide) dug into the lowest part of your basement or crawl space. It’s lined with a durable plastic or metal basin to keep the surrounding soil from collapsing into the hole. The pit collects water that seeps into your basement through drains, cracks in the foundation, or natural groundwater.
• The pump: This is the heart of the system. When water fills the pit to a certain level, the pump kicks into action. It’s designed to move water quickly—most pumps can handle 25–35 gallons of water per minute.
• The discharge pipe: Once the pump activates, it pushes water through a pipe that directs it away from your home’s foundation. This pipe usually leads to a storm drain, a dry well, or a slope that carries water downhill.

How water triggers the pump

The magic happens thanks to a float switch, which acts like a traffic light for your pump. Here’s how it works:

• The float switch is a small device attached to the pump. As water rises in the pit, the float (often a bulb or ball) rises with it.
• When the water reaches a set height (usually 6–12 inches deep), the float triggers the pump to turn on.
• Once the pump removes enough water and the float drops back down, the pump shuts off automatically.

Types of sump pumps

There are two main types of sump pumps:

Submersible sump pumps: These pumps are installed inside the sump pit and are submerged in water. They are generally quieter and more effective at removing large volumes of water.

Pedestal sump pumps: These pumps have a motor that sits above the sump pit, with a hose extending down into the water. They are typically less expensive than submersible pumps, but can be noisier and less efficient.

Why a sump pump is a necessity in flood-prone areas

Flood prevention: The most obvious benefit is keeping your basement dry. By automatically pumping out water, a sump pump prevents flooding that can damage your belongings, ruin your flooring, and create a breeding ground for mold.

Mold and mildew prevention: Excess moisture in your basement can lead to the growth of mold and mildew. These may result in allergies, respiratory conditions, and other health problems. A sump pump helps keep the area dry, preventing mold and mildew from taking hold.

Foundation protection: Waterlogged soil around your foundation can exert pressure on the walls, leading to cracks and structural damage. By removing excess water, a sump pump helps protect your foundation from costly repairs.

Increased property value: A dry, mold-free basement is a major selling point for potential homebuyers. Installing a sump pump can increase the value of your home and make it more attractive to buyers.

Peace of mind: Knowing that you have a reliable system in place to protect your home from flooding can bring significant peace of mind, especially during heavy rain events.

Choosing the right sump pump

Selecting the correct sump pump is based upon numerous elements, including the scale of your house, the common water table level, and the quantity of rainfall within the region. It’s advisable to seek advice from a plumbing expert like Haltex Plumbing to evaluate your individual requirements for sump pump installation and propose the most appropriate pump for your house.

• Pump capacity: Sump pumps are rated by their pumping capacity, measured in gallons per hour (GPH). The right capacity will depend on the size of your basement and the amount of water you typically need to remove.
• Horsepower: Sump pump motors also come in different horsepower ratings. A higher horsepower motor will pump water more quickly and efficiently.
• Power source: Most sump pumps run on electricity. However, consider a battery backup system in case of power outages during storms.
• Features: Look for features like automatic shut-off, alarm systems, and clog-resistant intakes.

FAQs About Sump Pumps

Q: How long do sump pumps last?

A: Sump pumps typically last between 7 and 10 years, but this can vary depending on usage and maintenance. Regular inspection and timely replacement are critical.

Q: How can I determine the appropriate sump pump size?

A: The size of the sump pump depends on several factors, including the size of your basement, the depth of the water table, and the frequency of flooding in your area. A professional plumber can assess your needs and recommend the appropriate size.

Q: What happens if my sump pump fails during a flood?

A: If your sump pump fails, water can quickly accumulate in your basement, leading to flooding and damage. A battery backup system can provide temporary protection during power outages. It is advisable to have a secondary pump installed.

Q: How often should I maintain my sump pump?

A: It’s best to inspect and test your sump pump at least twice a year, typically in the spring and fall. Regular cleaning and maintenance can help extend the life of your pump and ensure it operates efficiently.

Q: Can I install a sump pump myself?

A: While it’s possible to install a sump pump yourself, it’s generally best to hire a professional plumber. A plumber can ensure that the pump is properly installed and connected to the discharge line, minimizing the risk of problems down the road.
