Symptoms

- Standing water after rain near a low spot with a drain
- Grate is visibly covered in leaves or debris
- Drain worked fine before a recent storm or lawn work
Likely causes
- CommonLeaves, dirt, or grass clippings clogging the grateYard debris is the most common cause of blocked area drains.
- CommonSediment settled inside the drain pipeDirt washed in by rain can accumulate and harden over time.
- PossibleRoots growing into the drain pipeNearby tree or shrub roots can intrude into underground drainage pipes.
- PossibleCollapsed or disconnected pipe sectionGround settling or old age can damage buried yard drain pipe.
What to do
- Remove the grate and clear out visible leaves, dirt, and debris by hand or with a small trowel.
- Use a garden hose to flush water into the drain and see if it flows freely once the grate area is clear.
- If flow is still poor, use a hand-crank drain snake or a hose-based drain-clearing attachment to clear the pipe a few feet in.
- Check nearby landscaping for grading that funnels excess debris toward the drain and consider redirecting it.
- If water still won't drain and there's a nearby cleanout access point, a plumber can snake deeper into the line.
- Regularly clear the grate, especially in fall, to prevent recurring clogs from leaves.
