How to Replace a Sprinkler Head | Elite Sprinkler

By Elite Sprinkler Systems · Published April 28, 2026

Sprinkler heads take more abuse than any other component in your irrigation system. Lawn mowers clip them, foot traffic crushes them, UV exposure degrades the plastic, and Michigan freeze-thaw cycles stress the fittings below. The good news is that knowing how to replace a sprinkler head is one of the most accessible DIY irrigation repairs. With a few basic tools and about 15 minutes per head, you can restore full coverage to your lawn.

When Does a Sprinkler Head Need Replacing?

Not every sprinkler problem requires a new head — sometimes a clogged nozzle just needs cleaning, or a tilted head just needs straightening. But certain symptoms indicate the head itself is done:

  • The body is visibly cracked or broken
  • The head will not pop up when the zone runs
  • The head pops up but will not retract back into the ground
  • The nozzle is broken and cannot hold a spray pattern
  • Water leaks from the base of the head around the body seal
  • The internal ratchet or adjustment mechanism no longer works

Tools and Materials You Need

  • A replacement sprinkler head that matches the existing head GPM and radius rating
  • A small shovel or garden trowel for digging around the head
  • Teflon thread seal tape
  • A PVC cutter or hacksaw (only if the riser or fitting is damaged)
  • A rag or small brush for cleaning the fitting threads

Step-by-Step: Replacing a Pop-Up Sprinkler Head

Follow these steps to replace a pop-up sprinkler head correctly. Whether you are replacing a Rain Bird, Hunter, or Toro head, the basic process is the same:

  • 1. Turn off the zone at the controller or shut off the water supply to prevent pressurizing the line while you work
  • 2. Dig carefully around the head with a trowel, exposing 3 to 4 inches of the riser or swing joint below the head
  • 3. Grip the head body firmly and unscrew it counterclockwise from the riser fitting — if it is stuck, use pliers on the head body, not the riser
  • 4. Once removed, clear any dirt or debris from the riser fitting threads and inspect the fitting for cracks
  • 5. Wrap two or three layers of Teflon tape clockwise around the threads of the new head inlet
  • 6. Thread the new head onto the riser by hand, then snug it with a quarter-turn using gentle force — do not overtighten
  • 7. Adjust the spray pattern arc, radius, and direction before backfilling so you can see where the water lands
  • 8. Backfill the soil around the head, making sure it sits at grade level with the surrounding turf, then run the zone to verify coverage

Brand-Specific Tips

While the replacement process is similar across brands, there are a few differences worth noting. Rain Bird spray heads and rotors use a pull-up stem and adjust with a flat-blade screwdriver on top of the nozzle. How to replace a Rain Bird sprinkler head is no different mechanically, but make sure you match the nozzle number for the correct radius. Hunter heads use a key slot adjustment on the top of the nozzle turret and offer tool-free arc adjustment on most Pro Spray models. Toro heads often use a different thread pitch on their nozzles, so Toro nozzles are not interchangeable with Rain Bird or Hunter. When in doubt, bring the old head to the hardware store and match it exactly.

Common Mistakes to Avoid

  • Installing a head with a different GPM rating than the other heads on the zone, which destroys uniform coverage
  • Overtightening the head onto the riser, which cracks the fitting and creates a leak below grade
  • Forgetting Teflon tape, which leads to a slow drip at the connection that erodes soil and tilts the head
  • Not matching the precipitation rate — spray heads and rotors apply water at very different rates and must never share a zone
  • Setting the head too high above grade, making it a target for mower blades and foot traffic
  • Setting the head too low, which blocks the spray pattern with surrounding turf
