How to Raise a Sprinkler Head that is Too Low in Mansfield
Maintaining a lush, green lawn is a point of pride for many homeowners in Mansfield. You invest time, energy, and money into feeding, mowing, and watering your grass. But even the best lawn care routine falls flat if your irrigation system cannot deliver water effectively. Over time, you might notice brown, dry patches appearing in your yard while areas right next to the sprinkler stay soaked. When you inspect the problem, you find the culprit: a sunken sprinkler head.

Grass grows thicker, soil settles, and thatch builds up over the years. Before you know it, sprinkler heads that once sat perfectly flush with the ground are now buried under an inch of soil and roots. A low sprinkler head blocks the water spray, limits coverage, and wastes water by flooding the immediate area. Fortunately, fixing this issue is a straightforward DIY repair that requires minimal experience.
By raising the sunken head to its proper height, you restore your irrigation efficiency and protect your landscaping investment. Read on to learn exactly how to adjust your sprinkler heads to keep your Mansfield lawn looking its absolute best.
Why Proper Sprinkler Height Matters
Sprinkler heads need to sit just above the soil line but low enough that your lawnmower blades pass cleanly over them. When a sprinkler head sinks too low, the water stream hits the surrounding grass blades and soil instead of projecting outward. This blockage severely restricts your spray pattern.
As a result, the area right next to the sprinkler becomes completely waterlogged. This excessive moisture can lead to fungal diseases and root rot. Meanwhile, the outer edges of your lawn receive zero water, leading to drought stress and dead patches. Correcting your sprinkler height ensures an even distribution of water, lowering your utility bills and promoting deep, healthy root growth across your entire yard.
Tools and Materials Needed
Before you start digging up the yard, gather the necessary supplies. Having everything within reach makes this DIY repair quick and seamless.
- Hand trowel or small shovel: A small, narrow tool works best. You need precision to avoid severing underground pipes or damaging the surrounding grass.
- PVC pipe cutters or a hacksaw: You might need these if you are working with longer lengths of PVC, though pre-cut risers usually do the trick.
- Cut-off risers or riser extensions: These threaded plastic tubes come in various lengths. A cut-off riser allows you to easily trim the plastic to the exact height you need.
- Pipe wrench or adjustable pliers: These help loosen stubborn, older sprinkler heads that have calcified or locked up over time.
- Teflon tape: Wrapping the threaded connections with this specialized plumbing tape guarantees a watertight, leak-free seal.
- Bucket or tarp: Placing your excavated soil on a small tarp or in a bucket keeps your surrounding grass clean and makes backfilling much easier.
- Replacement topsoil or sand: You may need a handful of fresh soil to properly level the ground around the newly raised head.
Step-by-Step Guide to Raising Your Sprinkler Head
You do not need to be a certified plumber or landscaper to perform this task. Just follow these eight simple steps to get your irrigation system back on track.
1. Turn Off the Water Supply
Safety and cleanliness always come first. Make absolutely sure your sprinkler system is turned off at the main controller. If your system runs on a timer, disable the automatic schedule temporarily. You do not want the zone you are working on to suddenly activate, leaving you drenched and filling your freshly dug hole with mud.
2. Locate and Dig Around the Sprinkler Head
Identify the exact sprinkler head causing the issue. Take your trowel and carefully cut a circle in the turf about four to six inches outward from the edge of the sprinkler. Dig straight down, removing the soil and grass in one solid plug if possible. Place this plug on your tarp.
Continue scooping out the soil carefully until you completely expose the body of the sprinkler and the underground pipe it attaches to. Dig carefully to avoid striking the PVC pipe or flexible tubing below, as a crack will turn a simple adjustment into a major repair project.
3. Unscrew the Sprinkler Head
With the pipe and fittings exposed, grasp the main body of the sprinkler head. Turn it counterclockwise to unscrew it from the underground riser. If the head feels stuck due to age or hard water deposits, use your adjustable pliers. Grip the base of the sprinkler head firmly but gently, applying steady pressure to break the seal. Avoid squeezing too hard, as you can easily crack the plastic casing. Set the sprinkler head aside.
4. Add a Riser or Extension
Look down into the hole to inspect the existing female threading on the underground pipe. Take a moment to measure or estimate the height difference needed to bring the sprinkler head back level with the soil surface.
Take your new threaded riser extension and wrap the bottom threads two or three times with Teflon tape. Screw this new riser directly into the underground pipe fitting. If you bought a cut-off riser, use your pipe cutters to trim the plastic to the exact necessary height before installation. Hand-tighten the riser until it feels snug and secure.
5. Reattach the Sprinkler Head
Inspect the sprinkler head you removed earlier. Wipe away any loose dirt or debris from the inlet screen at the bottom. Wrap the top threads of your newly installed riser with Teflon tape. Carefully thread the sprinkler head onto the riser, turning clockwise. Tighten it by hand until it is firmly secured. Do not overtighten, as this can strip the plastic threads and cause immediate leaks.
6. Test the Sprinkler
Do not fill the hole back in just yet. First, you must verify your work. Step away from the hole and turn your irrigation system back on, activating the specific zone you just repaired. Watch the newly raised sprinkler head closely.
Check for two things: First, ensure the water sprays freely over the top of the grass without obstruction. Second, look down into the exposed hole to check for leaks around your new threaded connections. If you spot water bubbling up from the base, turn off the system, remove the head, add more Teflon tape, and retighten.
7. Backfill the Hole
Once you confirm the sprinkler operates perfectly with no leaks, turn the water off again. Take the soil you removed earlier and carefully backfill the hole. Pack the dirt firmly around the body of the sprinkler to provide stability. If you managed to save the top layer of grass as a solid plug, slip it back over the sprinkler head like a collar and press it down firmly. The top of the sprinkler head should now sit perfectly flush with the soil line, just below the top of the grass blades.
8. Adjust the Sprinkler Head
Sometimes the process of unscrewing and reattaching the sprinkler alters its original spray pattern. Use a small flathead screwdriver or the specific adjustment tool provided by your sprinkler manufacturer to fine-tune the spray arc and distance. Make sure the water hits the lawn evenly and avoids spraying sidewalks, driveways, or the side of your house.
