Most head leaks are quick fixes when you have the right replacement part and know whether you're working with PVC, poly or funny-pipe supply lines. A local sprinkler pro can match the brand, adjust the height so mowers clear it and test the zone pressure so the new head doesn't pop again next month.

Why Sprinkler Heads Leak in McKinney
Mower strikes are the number-one cause: a wheel or blade catches a head that sits too high, snapping the riser or cracking the body.
McKinney sits on expansive clay that swells when wet and shrinks when dry. That movement pushes heads up an inch or two every season, making them easier to hit and stressing the threaded connection until it cracks. UV exposure and 100° summer days make older plastic brittle—you'll see a split along the seam or around the nozzle turret that sprays a fan of water instead of an arc.
Cheap big-box heads may look identical but use different thread pitch or inlet sizes, so the seal never seats right and water weeps at the base. If one zone runs at higher pressure than the head is rated for, the internal seal blows and the head streams constantly even when the system is off.
What Happens When You Call
The specialist will ask which zone is leaking and whether water runs when the system is off or only during that cycle—that tells them if it's a cracked case, a stuck valve downstream or a pressure issue.
On site, they'll pull the damaged head, check the swing-joint or riser for cracks and measure how far it sits above grade. If the riser is fine, they'll replace just the head, matching brand and nozzle so throw distance stays consistent with the rest of the zone. If the riser is cracked or pushed up by clay shift, they'll cut it back, add a flex coupling or swing joint to handle future ground movement and set the new head flush with the turf line so mowers clear it.
Before they leave, they'll run the zone to check spray pattern, adjust the arc and radius and confirm no other heads in that circuit are weeping at the base.

How to Avoid the Next Leak
Mark every head with a bright flag or solar stake so you and your lawn crew can see them before the mower does.
Set heads flush with the soil, not proud; McKinney's clay will lift them over time anyway. Swing joints and funny-pipe laterals flex as the ground moves, so the connection doesn't snap the first time clay swells. Replace any head older than eight years if it's showing cracks, discoloration or a wobbly nozzle—plastic fatigues in Texas heat and a two-dollar part can save a week of wasted water.
Run each zone once a month during the season and walk the circuit; early drips are easier to fix than a blown riser that floods the yard overnight.
