How Gophers Damage Drip Irrigation Systems

Gophers and drip irrigation are a destructive combination in Southern California landscapes.

Drip irrigation is standard in Southern California landscaping, and gophers have learned to exploit it. The combination of buried water lines and the moisture they deliver creates a serious problem for homeowners and property managers.

WHY GOPHERS CHEW IRRIGATION LINES

Gophers chew drip lines to access moisture directly and because lines obstruct their tunnel paths. Unlike hard PVC pipe, flexible drip tubing offers little resistance to gopher teeth. A single gopher can damage dozens of emitters and several sections of mainline tubing in a short period.

DETECTION

Signs of irrigation damage include plants wilting despite an active irrigation schedule, unusually wet spots appearing between irrigation cycles, and fresh gopher mounds near irrigation valve boxes or along drip line runs.

REPAIR AND PREVENTION

Repairing chewed irrigation lines without addressing the underlying gopher problem is a temporary fix. Gophers will return to the same tunnels and chew through new tubing. Remove the gophers first, then repair the irrigation.

Why Gophers Target Irrigation Lines

Pocket gophers tunnel through soil in search of roots, bulbs, and other plant material. Drip irrigation tubing and mainline pipe run through the same soil zone where gophers travel. The tubing itself isn't what attracts gophers — it's incidental contact during tunneling. However, once a gopher bites through a line and moisture accumulates, the area becomes more attractive to further tunneling activity. A single gopher can sever multiple lines across a large irrigation system in a short period.

Signs Your Irrigation Damage Is Gopher-Related

Unexplained wet spots in your yard that don't correspond to a scheduled irrigation zone are a strong indicator of gopher damage to mainline or drip tubing. Dry zones in an otherwise functioning system often indicate severed emitter lines. Fan-shaped mounds near garden beds or lawn areas confirm active gopher presence. If you're finding irrigation damage without a clear mechanical explanation, gophers are likely involved.

Fixing the Damage

Irrigation repair without addressing the gopher population is a temporary fix. Gophers will continue tunneling and severing lines until the infestation is controlled. The correct sequence is gopher control first, then irrigation repair — otherwise you may be repairing the same lines multiple times. Our 60-day guarantee means that if gophers return and damage irrigation again within the guarantee period, we retreat at no additional cost.

Preventing Future Damage

Some homeowners install wire mesh baskets around vulnerable planting areas or use armored irrigation tubing in high-pressure zones. These are supplemental measures — they don't replace professional gopher control but can reduce the severity of damage between service visits on properties with persistent pressure.
