Why is one zone of my sprinklers not turning on?

Usually a bad solenoid, a stuck valve diaphragm, or a wiring break between the controller and that valve. A repair tech can test each zone and isolate it fast.

Do I need a permit to repair backflow preventer issues in Lexington?

Repairs typically don't need a permit, but many local water providers require annual backflow testing by a certified tester, which most irrigation repair companies also offer.

Can sprinkler repair be done in winter?

Yes, though most companies recommend blowing out the system before hard freezes and doing major repairs in spring when you're ready to reactivate it for the season.

Irrigation and sprinkler system repair in Lexington, SC

Sprinkler systems in Lexington take a beating from clay soil shifts, tree roots, and the freeze-thaw swings we get most winters. This page is for homeowners who already have a system in the ground and need something fixed, not a new layout designed and installed.

Common calls include broken or clogged heads, a zone that won't shut off, a controller that stopped communicating with valves, mainline leaks after a hard freeze, and low pressure that means half the yard goes dry. Most repair techs in the area also handle backflow preventer testing and repair, which Lexington and Lexington County sometimes require for cross-connection compliance.

What it costs

Repair pricing depends on what's actually broken: a single head swap is a quick, low-cost fix, while a mainline leak that requires digging or a bad valve manifold takes more labor and parts. Systems with older, discontinued controllers sometimes cost more because parts have to be sourced or the whole controller replaced. Ask for a diagnostic visit first if the problem isn't obvious (like a wet spot in the yard with no clear head nearby).
