How to Extend Sprinkler Head: Simple Steps for Efficient Lawn Coverage

How to extend sprinkler head depends on your lawn’s size and shape. You can add pipe segments and connectors below the head to reach farther. Extending by about 6 feet covers 100 more square feet and waters tricky spots or patios better.

Start by digging near the sprinkler to expose the irrigation line carefully. Leave about 2 inches from the sprinkler’s base to protect the connector. Using proper lengths and couplers, like two 3-foot pipes joined, keeps good water flow.

Don’t extend your sprinkler beyond 10 to 15 feet or water won’t distribute evenly. You might have to move the lateral line for longer distances. Raising the head above plants helps water fall down nicely for full coverage.

What Does Extending a Sprinkler Head Involve?

Raising a sprinkler head means adding pipe to lift it above the ground. This helps the sprinkler reach farther to water plants more fully. Adding 6 feet in height can water 100 more square feet of lawn or garden.

Extend a sprinkler head to improve water coverage without changing the system. This saves time from moving or replacing the whole sprinkler. It’s a quick way to cover dry spots.

Moving a sprinkler over 15 feet usually means moving the pipe too. This work is more involved and takes extra time.

It can also disrupt your current irrigation setup. Extending is simpler and less expensive, letting you keep your current setup while improving water spread.

The main advantage of extending a sprinkler head is improved water coverage. Water reaches your grass or plants more evenly. This cuts down on dry patches and wasted water.

It helps water reach over plants or obstacles. Raising the sprinkler lets water fall naturally from above your plants.

This gentler spray reduces runoff and water waste. It’s better for your lawn’s health.

To extend a sprinkler head, first find it by turning your sprinkler system on. Then measure how much higher or further the sprinkler needs to be raised. Cut the riser pipe about 2 inches from the sprinkler head carefully.

Make sure the cut is straight and smooth. This step is key for a good fit. Attach an extension riser that fits the threads, making sure it connects tightly to avoid leaks.

Use a screwdriver to loosen the nut and take off the sprinkler head. This simple tool makes removing the head easy. Work slowly to avoid damage.

After adding the extension and securing the head again, turn your system back on. Check that the sprinkler still rotates properly and doesn’t leak.

Once everything works, refill the dirt around it so the riser is level with the lawn. That keeps it stable and prevents damage.

Different Types of Sprinkler Head Extensions

You can choose from several types of sprinkler head extensions to fit your lawn’s needs. Simple risers are straight pieces of pipe that raise the sprinkler higher.

Swing joint risers use flexible black tubing called funny pipe. This lets you adjust the sprinkler’s position easily.

Simple risers work well when you just need to lift a sprinkler for better coverage. Swing joint risers let you move the sprinkler head without digging.

This saves time and avoids pipe damage. Flexible risers are great for tricky spots or irregular terrain since they bend around obstacles.

Swing joint risers cost a bit more than regular ones. They are worth it if you may need to move sprinklers later.

Simple risers are cheaper and faster to install but don’t allow repositioning. Flexible risers reduce the chance of breakage when lawn maintenance happens.

Use rigid pipe extensions when your sprinkler heads sit on level ground with no obstacles. The straight riser keeps the sprinkler steady and easy to install.

Flexible risers help if roots or rocks make digging tough. They bend instead of breaking.

Always turn off your sprinkler system before installing or changing extensions to avoid leaks or damage.

Choosing the Right Materials and Tools

To extend a sprinkler head, you need specific tools and compatible parts. Pick the right pipe types, sizes, and fittings to avoid leaks and damage. Quality materials ensure your system stays strong and waters well.

Essential Tools for Extension

Start with a simple toolkit including a PVC cutter or hacksaw to trim pipes cleanly. Slip-joint pliers and an adjustable wrench help you tighten fittings properly. A shovel will be handy to carefully dig up the sprinkler head without damaging pipes.

Also have Teflon tape for sealing threaded joints, plus gloves and safety glasses for protection. These tools keep the job neat and make connections leak-free.

• PVC cutter or fine-toothed hacksaw
• Slip-joint pliers and adjustable wrench
• Shovel or hand trowel
• Teflon tape for sealing threads
• Gloves and safety glasses for safety

Choosing Pipes and Fittings

PVC pipe is the best choice for sprinklers because it handles pressure well and resists damage. Use Schedule 40 PVC with a ½-inch or ¾-inch diameter, depending on your existing system size. Avoid using garden hose or metal pipes, as they may not fit or hold pressure properly.

Fittings should match your existing connections and sprinkler head threads. Look for slip fittings or threaded adapters made for irrigation. Don’t mix different materials since that can cause leaks or corrosion.

Select parts rated for at least 80 psi pressure to match typical residential sprinkler systems. Check the packaging or product details to make sure components are designed for outdoor irrigation.

Recommended Sprinkler Head Risers

Risers act as the extension between the underground pipes and sprinkler heads. Choose risers that fit your sprinkler’s thread size and type, usually ½-inch male or female threads. PVC or polyethylene risers work well, but PVC is preferred for durability.

Flexible risers let you adjust the head height easily and absorb ground movements. For best results, use risers 12 inches or shorter. Long risers can cause pressure loss.

They may also cause uneven watering. Secure the riser firmly with Teflon tape and hand-tighten fittings to prevent leaks.

Measuring and Planning Your Sprinkler Head Extension

Start by measuring how far you want to extend the sprinkler head. Then check for slopes, plants, or obstacles that might affect water coverage. Finally, figure out a safe extension length that keeps water pressure steady.

Measuring Distance from Existing Head

First, uncover the pipe just a few inches from the sprinkler head. Gently pull back the grass and flip the sprinkler head upside down on the lawn. This lets you mark exactly where the old head sat.

Measure from this spot to where you want the water to reach. Use a tape measure or measuring wheel for accuracy, noting key plants or lawn edges. Make a note of this distance because it guides the extension length.

Here’s how to measure the extension length correctly:

1. Dig a few inches around the current sprinkler head to expose the base.
2. Lift the sprinkler head and flip it so you see the side touching the ground.
3. Mark this exact spot with a stake or flag in the lawn.
4. Use a tape measure from the marked spot to the target watering area.
5. Record this distance for planning your extension tube or arm.

Assessing Terrain and Obstructions

Look for hills, dips, trees, or fences that might block the spray. Water sprays in an arc and can be cut off by slopes or objects.

Account for raised or lowered parts of your lawn to keep water spraying evenly. Steep slopes might need shorter extension or special nozzles that adjust spray angle.

Plan the extension route to curve around plants or structures. Avoid running the extension through flower beds where it might cause damage or leaks.

Determining Maximum Extension Length

Check your sprinkler system’s water pressure before deciding on extension length. Too long or too many extensions lower pressure, reducing spray distance.

Most sprinkler head extensions stay under 12 inches for good coverage and pressure. Going beyond 18 inches starts to risk weak spray and uneven coverage. Follow these steps to pick a safe extension length:

1. Find your system’s water pressure on the valve or controller label.
2. Compare pressure to the sprinkler head’s specs to find max recommended extension.
3. Keep your extension under 12 inches for typical home systems to avoid pressure loss.
4. Test spray after installation. If water jets weak or coverage drops, shorten extension.

Step-by-Step Guide to Extending a Sprinkler Head

To extend a sprinkler head, start by digging around it. Next, remove the old head or riser carefully. Then add extension parts and reinstall the head.

This process raises the head to water farther or uneven terrain better. Follow the steps carefully to avoid leaks and poor watering coverage.

Preparing the Site and Turning Off Water

First, shut off the water supply to your irrigation zone. This prevents any unexpected sprays or water damage while working. Use the main valve or your sprinkler system’s controller to stop water flow.

Next, clear the ground near the sprinkler. Remove any grass, mulch, or debris within a foot radius of the sprinkler head. This gives you room to work and protects your tools and parts from dirt.

Removing the Existing Sprinkler Head

Carefully dig around the sprinkler head with a small shovel or hand trowel. Dig about 6 to 8 inches deep to expose the riser and pipe without damaging them. You’ll find the riser attached to the water line.

Unscrew the sprinkler head or riser by hand. Turn it counterclockwise to loosen. Use a pipe wrench gently to loosen it.

Avoid cracking the riser while doing this. Remove the head completely while keeping the riser intact if possible.

Take care not to crack nearby pipes when digging or removing the head.

Installing the Extension and Reattaching the Head

Attach the extension piece to the riser. Make sure it aligns straight with the riser’s outlet. Twist it on clockwise until it feels secure but don’t overtighten to avoid stripping threads.

Next, screw the sprinkler head onto the extension. You may need to add thread seal tape around connections to prevent leaks.

Secure clips or screws typically come with extensions. Use those to lock parts firmly in place.

Testing and Final Adjustments

Turn the water back on at the valve or control box. Watch the sprinkler closely. Check for leaks at the joints and ensure water sprays evenly across the intended area.

Adjust the sprinkler head height or swivel it slightly for better coverage. Tighten any loose connections on the sprinkler. Then cover soil around it again.

Leave the head stable just above ground level. Watch for dry spots over the next few days.

1. Turn off water supply at the irrigation controller or main valve.
2. Clear vegetation and soil around the sprinkler head carefully.
3. Dig around the sprinkler head, exposing the riser by 6-8 inches.
4. Unscrew and remove the existing sprinkler head or riser.
5. Attach the extension straight onto the riser, twisting clockwise.
6. Screw the sprinkler head onto the extension, adding thread tape if needed.
7. Turn the water back on and check for leaks and spray pattern.
8. Adjust the head angle and height for even watering and secure soil back.

Common Problems and How to Fix Them

Leaks often happen at the connection points after extending a sprinkler head. Check all joints for tight seals.

Use Teflon tape on threaded parts to stop water leaks. Tightening connections with pliers helps, but avoid overtightening to prevent damage.

Uneven spray or watering gaps usually mean the sprinkler head isn’t aligned or extended right. Adjust the spray angle by twisting the nozzle or setting the deflector shield.

Make sure the sprinkler head extension raises the nozzle above any plants blocking spray. Gaps mean you should move the head or add an extension.

Clogged nozzles happen because dirt and debris enter during installation or from soil splash. Remove the nozzle first. Soak it in vinegar for 10 to 15 minutes.

This helps clear mineral buildup. Use a soft brush or a thin wire to gently clean the nozzle holes. Never use sharp tools that might widen the openings.

Low water pressure can come from too long an extension. It can also happen if the pipe diameter is too small. Keep extensions under 12 inches to maintain good pressure.

Check your water source for issues too. Pressure stays low? Try a booster pump or wider pipes for the extension.

• Use Teflon tape to seal threaded connections tightly.
• Align sprinkler heads to avoid watering shadows or dry spots.
• Soak nozzles in vinegar to dissolve mineral deposits.
• Clean nozzles gently with a soft brush or wire.
• Limit extension length to prevent pressure loss.
• Test water pressure at the source if performance drops.

Addressing these problems quickly keeps your sprinkler system working well. Problems like leaks and clogs can waste water and harm plants.

Fixing issues takes little time but saves water and keeps your lawn green. Regular checks after extension will spot problems before they grow.

Maintaining Extended Sprinkler Heads for Longevity

Inspect your extended sprinkler heads every month during the irrigation season. Check for leaks, misalignment, or damage caused by lawn equipment or foot traffic. Regular checks catch small problems before they reduce water coverage or cause bigger repairs.

Cleaning sprinkler heads prevents clogging and poor spray patterns. Remove any dirt, grass, or debris blocking the nozzle or filter screen.

You can gently brush the head or rinse it with water. Use a soft wire or pin to clear any mineral deposits inside the nozzle.

Winterizing your sprinkler system protects it from freeze damage. Before the first hard freeze, drain all water from the pipes and heads.

Blow them out with compressed air if you have a system blower. Cover extended heads with protective caps or insulated covers to prevent cracking or warping.

• Check for leaks, broken parts, or misalignment monthly
• Clear debris and flush nozzle and filters regularly
• Use a soft brush or pin to remove mineral buildup
• Drain water before freezing weather and blow out pipes
• Cover extended heads in winter with caps or insulation

Extended sprinkler heads can wear out seals and risers faster than standard heads. Look for cracks in the extension tube or head riser.

Replace damaged parts promptly to avoid leaks. Most repair parts cost under $10 and save you trips to buy new heads.

Proper maintenance keeps your watering zones even and your lawn healthy. Overwatering or dry spots often result from head misalignment or clogged extensions.

Spend 10 to 15 minutes monthly on these simple steps. It helps your system run longer and keeps your yard green without wasting water.

When to Call a Professional for Sprinkler Extensions

Extending a sprinkler head might seem simple. But call a pro if you face complicated issues. You should hire a professional for unusual sprinkler system damage.

Cracked pipes or broken valves usually need expert repairs. These problems need special tools and experience to fix without causing leaks or reducing water pressure.

A key sign to call an expert is if the irrigation zone malfunctions. It may not turn on or off properly after extension. Incorrect wiring or valve problems often cause this.

If your sprinkler head sits on uneven ground, get a pro. They make sure it stays stable and sprays evenly.

Call a professional when underground utilities are near the sprinkler lines. This avoids accidents and damage.

Digging near electric, gas, or water lines is risky and sometimes requires permits or special equipment. A licensed installer knows how to work safely in these conditions.

Before hiring, ask the pro about their sprinkler extension experience. Check if they have the right licenses too. You want to make sure they understand your irrigation system type.

Also, ask if they provide a written estimate, including labor and parts. This helps avoid surprise costs.

Discuss the warranty on their work and installed parts. A solid warranty often means the pro stands behind their work.

Ask how long the job will take before hiring. Also, find out how they protect your lawn during repairs.

Labor can cost between $50 and $100 per hour, plus parts. Complex jobs near utility lines or old systems might need more time and cost more. Simple extensions could take an hour or less, costing under $150 total.

Don’t extend sprinkler heads near hidden utility lines yourself. It’s risky and can lead to costly damage.
