Best Crawl Space Sump Pumps

Crawl spaces are subterranean basements beneath your house or mobile home. They may not be large enough to walk around in, but they can hold a few boxes and, unfortunately, suffer from the same water and flooding issues as basements.

Build a pump pit in every crawl space home to protect the foundation and structure against water damage. This is especially crucial if you reside near a river, flood plain, or below the area’s water table! 

In some circumstances, especially in locations with the best drainage pipes, it may not be necessary, but why take the risk?

Crawl space sump pump: How to Install it?

Installing the best crawl space sump pump is similar to installing one in your basement, with a few exceptions. Let’s go over a crawl space sump pump step-by-step installation procedure so you may save money and avoid paying for professional installation.

The main difference is that you won’t be able to stand up straight when digging your pit! Crawl spaces are much smaller than basements, making excavating difficult, especially if it is beneath a concrete floor or a mobile home.

Step-by-Step Instructions

Installing a crawl space sump pump isn’t challenging; you must follow the installation instructions attentively to make it easy. To ensure correct installation, follow the steps below:

  • Locate the finest location – Keep an eye out for pools of water and excavate your pump pit to avoid a flooded crawl space. Include space for drainage pipe, alarm, backup battery, and electrical connections.
  • Dig your Pit – Next, begin digging your crawlspace pit. The difficulty here varies based on how much space you have to work with and how far you are from the access point.
  • Install the Basin – After digging your hole, place the basin in it. A decent pump basin is just as crucial as the pump itself. The basin should be large enough to regulate flood water and fit snugly inside your pit hole. If the basin does not have a cover, installing a sump pump liner or vapor barrier is also a good opportunity.
  • Install the Pump – Place the pump in your basin. Check that the pump stands appropriately and that nothing is blocking the valves. Also, double-check that the electrical connections are sufficiently separated from the water supply and that there are no plumbing leaks.
  • Install Drainage Lines – Your discharge piping is just as crucial as your pump. You can clear the standing water with clean lines free of obstructions.
  • Test the Pump – Once everything is in place, fill a few buckets with water to ensure your new pump is operational. When the basin fills, the system should activate and begin draining it.

By following these steps, you will surely get your crawl space sump pump appropriately installed.

Pump basins in crawl space

You must first dig a sump pit and a basin before installing a pump. Your basin should snugly fit into your hole. The optimal location for your basin is at the lowest point of your crawl space or wherever water collects.


Remember to clean and service your basin regularly. Particles and other minute items can accumulate over time, causing issues with the pump and clogging drainage channels.

Tips for basin installation

Installing a basin is a great way to control excess water and ensure your crawl space stays dry. But it’s essential to do the job correctly to ensure it’s effective. Here are a few tips to help you with basin installation: 

  • First, finding a suitable basin for your needs is essential. Look for a large enough basin for your crawl space sump pump, and ensure it can handle the amount of water you’ll be pumping out. 
  • Second, check local codes to ensure your basin is up to code. This can save you from legal trouble. Third, ensure you have all tools and supplies before starting the job. 
  • Finally, have a friend help you with the installation. They can offer assistance and an extra set of eyes to ensure it’s done right. 

With these tips, you’re sure to have a successful basin installation!

Cost of the best crawl space sump pump installation

The cost of the best crawl space sump pump installation varies according to the job’s difficulty. Installing a pump pit in a crawl area typically costs around $1000. This figure may appear hefty, but remember that a pump alone costs around $200. 

Costs vary by state and can be significantly expensive if you need to obtain a permit. You can save money digging the pit and installing the pump, but you’ll need a shovel, drainage pipes, and a few hours of spare time!

Wrapping up

When it comes to protecting your home from water damage, choosing the best crawl space sump pump is essential. When shopping for a pump, consider your specific needs and pick a sump pump that is efficient and sturdy enough to handle the job.

The top picks for the best crawl space sump pumps are all high-quality and reliable. They are all suitable for use in all types of settings and will help to keep your home safe from water damage.
