We repair and troubleshoot existing residential sprinkler systems, including valves, solenoids, wiring, buried valves, heads, nozzles, underground leaks, low pressure, controllers, spring start-up, winterization, irrigation-supply issues and low-voltage landscape-lighting repair.
Our primary focus is repair, diagnostics and maintenance of existing residential irrigation systems rather than new-system installation.
Fort Mill Irrigation has irrigation service experience dating to 1996.
Core service areas include Fort Mill, Tega Cay, Indian Land, Rock Hill, Lake Wylie, Clover, York, Pineville, Ballantyne and Lancaster.
Call or text Fort Mill Irrigation at (803) 710-8008 and describe your location and what the sprinkler system is doing.
A dead zone can be caused by controller output, field wiring, a failed solenoid, a valve problem or a water-supply issue. Testing helps separate electrical, mechanical and hydraulic causes.
A valve that cannot seal because of debris, diaphragm damage or internal wear may continue passing water after the controller stops sending power.
Hidden leaks, a valve that is not opening fully, damaged piping, excessive nozzle demand or another flow restriction can reduce operating pressure on one zone.
Yes. Valve locating and wire tracing can help narrow the search when a valve box is buried or no longer visible.
The source may be a valve, nearby fitting, lateral line or surrounding drainage. Observing when the water appears helps narrow the cause.
After the risk of hard freezing has passed and the landscape begins needing supplemental irrigation. A careful start-up also helps identify winter damage and control problems.
Schedule in the fall before sustained freezing weather arrives. Earlier scheduling also avoids the rush immediately before a freeze.
Yes. Freezing weather can damage water-filled irrigation components, especially exposed piping and water trapped in lines, valves and heads.
Rain-sensor configuration, smart-controller weather settings or schedule programming may be involved.
No. Irrigation demand changes with temperature, rainfall, plant growth and season, so schedules should be adjusted rather than left unchanged year-round.
Yes. We troubleshoot Rachio-equipped residential systems as well as common Rain Bird and Hunter controls.
The solenoid is the electrical actuator on an irrigation valve. When energized by the controller, it helps the valve open so water can flow to the zone.
Yes. Multiple valves can share a common conductor, so damage to that common circuit can affect several zones at once.
The controller may be sending a signal while a wiring, solenoid, valve or water-supply problem prevents irrigation in the yard.
Multiple programs, duplicate start times or schedule settings can create repeated watering cycles.
Residual water can drain toward the lowest head after shutdown, or a valve may be seeping and continuing to feed the zone. The pattern helps distinguish the cause.
Low pressure, debris, a damaged head, a leak or a valve/flow problem can all prevent heads from rising normally.
Root growth and soil movement can place stress on shallow irrigation piping and fittings, and landscape work around roots can also cause damage.
The head body, riser, fitting or nearby lateral line may be damaged and leaking under pressure.
Yes. Water escaping underground reduces the flow available to sprinkler heads downstream.
