Explained: How a Basement Walkout Drain Works

Riverton, Utah Basement Walkout Entry

Hello, Caleb Dansie with Dansie Design Build. Today, I want to talk to you about basement walkout drains. So we’re in a basement walkout that we’re currently building in Riverton, Utah. It’s under construction, and I wanted to show you how the drain works; it’s also a follow-up to another video I made talking about how we built them. The basement walkout entry has a five by five feet landing at the bottom, and the door is a standard three-foot door with full light glass.

Gravel Field for a Basement Walkout Drain

So down at the bottom, we dig down a couple of feet and fill the area with gravel. So it’s essential to have the right size of gravel, which would be one inch; that gives up a lot of space around each of the rocks.

How a Basement Drain Works

Then there is the actual drain. The drain is a piece of plastic from the factory, so we can pour the concrete and keep it clean; it’s connected to a five-gallon bucket that’s turned upside down and has many holes drilled on all the sides. So the way it works is:

Step 1: The water comes down into the upside-down 5-gallon bucket.

Step 2: Then, the water percolates into the gravel.

Step 3: Lastly, the water goes from the gravel field to the soils below and around it.


So that’s how a basement walkout drain allows the water space to escape. And then, over time, if you need to, you can spin this drain open, pull out any build-up, and put a vacuum hose down there to clean it; it’s accessible and serviceable if you need to do anything to it later.
