Irrigation Installation and Repair in Central Florida
Irrigation installation and repair keeps a Florida lawn alive between summer storms. We put in new sprinkler systems, rebuild failed valves, chase down broken lines and replace lake pumps across Volusia, Lake and Seminole counties, then walk every zone before we call it done.
What goes into a new sprinkler system installation?
A call to 811, a zone plan, and valves you can get back to later. Florida law requires two full business days notice before digging. The call is free. Then the yard gets split into zones by what's growing there, how much sun each part of it gets through the day, and how fast the sand under it drains. A burned out strip beside a road becomes its own zone with its own run time instead of sharing one with shaded beds.
On our DeLand frontage job the manifold was schedule 40 PVC with three inline valves off a common main. The purple at every joint is primer, dyed so an inspector can confirm the pipe was primed before it was cemented. Control wire gets spliced in waterproof connectors. Never wire nuts. The valves sit in a valve box so nobody has to dig them up to service them. Heads are set back from the edge and fitted with adjustable arc nozzles, with quarter and half circle heads matched so every part of a zone gets the same amount of water. That's the standard at Roeling Green Lawns, whether it's a front strip or a whole property.
Can you replace an irrigation pump that pulls from a lake?
Yes. Plenty of Volusia County lawns water from a lake, a well or a reuse line, and pumps fail like anything else left at the water's edge. The DeLand pump we replaced was rusted through on its concrete pad, with sun bleached PVC patched above it, and it could no longer pull the pressure the lawn needed.
The diagnosis ran from the foot of the suction line out in the cattails all the way to the control box. We shut the system down, drained it and broke the old pump free of its fittings. New white PVC supply lines went in beside the existing purple reclaimed line, then the new unit got clean risers, a fresh priming setup and control wiring run back to its box. The last step matters most: test every zone and check the suction side for air leaks, because a pump sucking air loses pressure long before anyone sees a problem. The full story is on our lakefront irrigation pump replacement in DeLand.
How do you find a broken irrigation line underground?
With a locator, not a shovel. When a Sanford homeowner called about a soggy, blown out patch of lawn with water pooling around it, the first tool out of the truck was a wire and valve locator: a transmitter, a clamp, headphones and a probe. Energizing the control wiring lets us trace buried lines and valves without trenching half the yard to find them.
What we dug up was typical of an older Central Florida system. A maze of old PVC elbows and tees. Bare low voltage wires tangled through the dirt and the roots. The cause was root pressure, ground movement and glue joints that had simply aged out. We cut a neat, narrow trench, laid fresh poly line and new wiring, kept the cut tight enough that the sod could be folded back over, then tested the zones and backfilled flush. You can see each step of that irrigation repair in Sanford, including the dig beside a curbside fire hydrant.
Why do sprinkler zones stop turning on?
Usually a failed valve, a cracked fitting, or wiring that corroded underground. The Winter Park manifold we rebuilt had all three: aged, dirt caked PVC, a cracked fitting and a tangle of low voltage wire that had corroded until the controller couldn't fire the zones anymore. Patching one piece of a manifold like that just moves the failure to the next joint.
So the whole assembly came out. Fresh PVC and new zone valves went in, with every joint cut square, primed and glued, and new wiring run to each valve. Then we pressure tested it, confirmed each valve opens and closes on command, and checked the zones for full coverage with no dry gaps and no geysers. You can compare that sprinkler system repair in Winter Park with the new sprinkler system installation in DeLand, where a brand new system went in from scratch on a burned out road strip.
Does a Florida irrigation system need a rain sensor?
Yes. Florida Statute 373.62 requires an automatic landscape irrigation system to have a working rain sensor or another shutoff device, so the sprinklers don't run in the middle of an afternoon storm. If your system is more than five or six years old, the sensor is the first thing worth testing. They fail quietly, and a dead one means you're watering in the rain.
Schedules matter just as much. Volusia County sits inside the St. Johns River Water Management District, which limits established lawns to two watering days a week during daylight saving time and one day a week the rest of the year. New sod gets a heavier establishment allowance for its first weeks. Check the current rules with the district before you set a schedule. When we finish a job, the controller gets programmed to a real schedule rather than the factory default, and someone walks every zone while it runs. If you're pairing a new system with sod installation, we set the heads to the finished grade before the sod goes down.
