Is basement flooding a concern for you? If yes, then a sump pump and a sump pit may be the answer to keeping your basement dry.

Schedule Free Inspection

Whenever it rains in Denver, Colorado, the soil surrounding your home gets saturated and groundwater rises. This puts your basement at risk of flooding. But that’s not the only risk. Faulty laundry machines, leaky water heaters, and burst pipes can inundate the basement with water.

To protect your home’s structural integrity and avert water damage, you’ll need to invest in a quality sump pump. For your sump pump to function optimally, it needs a sump pit.

What is a sump pit?

A sump pit, also known as a sump crock, is a basin situated at the lowest spot in the basement. It collects floodwater before the motor pumps it out to a suitable discharge area. This reservoir sits below the floor and has a lid at the top. The pit’s edges are often sealed and smoothed with pre-mixed mortar. 

To create a sump pit, the basement specialist must cut a hole in the floor or jackhammer the floor. The sump pump and intake are then lowered to the resulting basin.

How it works

The sump pit has an integral float that triggers the pump’s motor whenever water reaches a certain level to prevent flooding. The pump’s motor then starts pumping out water. As the water levels drop, the switch also goes down and the pump shuts off at a certain point. The float also ensures that the sump pit cannot overflow except during extreme circumstances.

Common Misconceptions About Sump Pits

Unfortunately, some homeowners hold wrong beliefs about sump pits and their purpose, which denies them the opportunity to maximize their sump pumps. Let’s dispel some of those myths.

Sump pits occupy valuable space: False. Submersible pumps like Safedri™ are usually compact and installed over the sump pit. Because the pump goes beneath your basement floor, it’s not going to take up space.

Sump pit systems are complicated: Another myth that holds people back is that sump pits are complex. It is a two-and-a-half-foot hole that’s sunk onto the floor and its edges smoothened with pre-mixed mortar.

Sump pits are optional: You never know what the weather could throw your way. The moderate rains or occasional floods could give way to nasty hail storms and severe flooding. Without a sump pit, you may find yourself amid a disaster.

Sump pits fail a lot: Some homeowners fear installing sump pits because they believe they will ultimately fail due to power outages, poor installation, product defects, or clogged discharge lines. That’s unlikely to happen if these fixtures are properly supported.

Is a sump pit necessary?

Keeping your basement dry is vital for the safety and integrity of your home’s foundation. Otherwise, water can devastate both your basement and your finances. Plus, the flood doesn’t have to be big for it to damage your home. Even the smallest leak or crack in your house structure can lead to severe water damage in your home.

Basement flooding and dampness are due in part to inclement weather and a poorly built foundation. The other part of the equation is the system that controls your water flow—the sump pit and the sump pump. If your basement experiences regular flooding issues, installing a sump pump and a sump pit can help remedy the problem. Note that a sump pump does not address the source of your water problem.

How does a sump pit benefit your home? 

Your basement is at risk for water damage every time it rains. Although a sump basin does not address the root cause of water in your basement, it helps alleviate water damage by ejecting standing water. In addition to helping you drain water out and away from your basement, a sump pit protects your foundation’s structural integrity.

Standing water in the basement creates the perfect environment for mold and mildew growth. It also gives rise to a damp or smelly environment. Over time, the standing water may damage your foundation. The installation of a sump pump and pit helps to drain out this water leaving you with a drier, healthier basement. Other benefits of a sump pump system include:

  • Keeps basement humidity levels low 
  • Improves indoor air quality by reducing humidity 
  • Protects your paint from potential peeling
