How to Maintain Your Landscape Drainage System for Long-Lasting Efficiency

A drainage system needs a clear way to collect water and a clear way to discharge it. Routine checks help you catch debris, damaged connections, and changing ground conditions before the next rain exposes the problem.

Start with visible components. If the system keeps backing up, cleaning the grate alone may not be enough.

Inspect the inlets

• Clear leaves, mulch, and loose debris from the tops of catch-basin and channel-drain grates.

• Check whether nearby soil or landscaping keeps water from reaching the inlet.

• Look for broken grates, loose connections, or movement around the basin.

• Keep grates installed where people can access the area.

An inlet can be clean but too high for the surrounding low spot. That is a collection problem rather than a pipe-cleaning problem.

Check roof-water connections

Look for water escaping from downspouts before it enters the buried extension. Check visible cleanouts and fittings for damage or displacement. Gutter problems and underground pipe problems need to be distinguished.

Locate the outlet

Find the pop-up emitter or other discharge point. Check for covering grass, sediment, restricted openings, or new erosion. Follow the receiving surface route far enough to see whether water has somewhere to go.

Don't bury an outlet under new landscaping or assume that an emitter is unlimited relief for an overloaded system.

Include pumps where present

Exterior pump systems need equipment-specific inspection and service. Check normal activation and discharge with an appropriate test, while respecting electrical and access conditions.

A pump can stop working because of power loss, debris, control problems, or a restricted discharge. Avoid opening energized equipment or entering an unsafe flooded area.

Test before choosing a repair

A controlled flow test can help trace a known route and compare inlet and outlet behavior. Its flow is not automatically equivalent to a major storm, and water emerging from one outlet doesn't prove every branch is clear.

Professional inspection and cleaning may be needed when the route is unknown, water backs up, roots are suspected, or a buried connection may be damaged. Don't force a hose or cutting tool into unfamiliar pipe or trim roots around utilities based on a blanket tip.

Keep maintenance tied to the actual system

Record the inlets, cleanouts, pipe routes, and discharge points. Note changes after storms. Retain the scope and service information so repairs can address the existing installation instead of adding unnecessary pipe.

Ask us about inspection and cleaning for your system. Any maintenance plan or warranty condition should be confirmed in your current written agreement.
