If an outdoor area drain is clogged, start by clearing leaves, dirt, and debris from the grate and the top of the drain. If water still will not go down, the blockage is likely deeper in the pipe and may need a drain cable or water jetting to clear it.
Where Outdoor Drains Are Found
Area drains are often set in patios, driveways, basement stairwells, and low spots in the yard. Their job is to collect rainwater and carry it away from the house. When they clog, water can pool against the foundation or flow toward a basement door. Checking them before storms is a simple habit that helps.
Common Causes of Clogs
- Leaves, twigs, and grass clippings
- Sand, soil, and mulch washed in by rain
- Ice in winter
- Tree roots growing into underground pipes
- A crushed or broken pipe under the ground
What You Can Do
Wear gloves and lift the grate if it comes off easily. Scoop out debris by hand or with a small trowel. Run a garden hose into the drain to see if water flows. A small hand auger can sometimes reach shallow clogs. Avoid pouring chemicals into outdoor drains, since they can harm plants and local waterways.
Never step into a stairwell drain area filled with deep water, and keep away from any outlets or lights nearby.
When It Needs More
If water backs up right after clearing the top, the clog is deeper. Roots, packed sediment, or a broken pipe often need professional tools or a camera to find. A stairwell drain that keeps flooding near a basement door should be fixed before the next big storm.
When an outdoor line stays blocked, clearing the drain pipe beneath the grate can stop water from pooling. For broader drainage problems around the house, you can have a plumber look at where the water goes at (833) 603-1840.
