Inspect your sprinkler heads and pipes. Replace any broken heads and fix leaks to ensure even watering.

Muddy Areas

Muddy or soggy areas in your lawn often point to:

• Large leaks: Significant water loss can cause these spots.
• Faulty valves: Valves that don’t close properly can lead to overwatering.

Check for leaks and test your valves. Repair or replace any faulty components to prevent overwatering.

Faulty Valves

Valves control water flow to different zones. Signs of a faulty valve include:

• Uncontrollable water pressure: If the sprinkler keeps leaking after shut-off, the valve might be faulty.
• Water won’t shut off: This could indicate a bad solenoid or other electrical issues.

Replace faulty valves to restore proper function. If the problem persists, check the solenoid and electrical connections.

Damaged Pipes

Pipes can get damaged by tree roots, heavy equipment, or ground shifts. Signs of damaged pipes include:

If the riser is damaged, replace it. Measure the new riser against the old one and cut it to size using a PVC pipe-cutting tool.

Tip: Cut-off risers are a good option because they can be easily adjusted to the correct length.

Install the new riser by threading it into the base of the sprinkler system. Hand-tighten it until it’s secure, but don’t over-tighten.

Clean and Prepare for Installation

Before installing the new sprinkler head, scoop out any water from the hole. Use a toothbrush to clean the spout and remove any debris.

Wrap plumber’s tape around the threads of the new sprinkler head. This ensures a tight seal and prevents leaks.

Install New Components

Place the new sprinkler head onto the riser and hand-tighten it. Make sure it’s snug but not over-tightened.

Tip: Flush out any dirt that may have fallen into the water line before installing the new head. This prevents clogs and ensures smooth operation.

Test and Adjust

Turn on the water supply and test the sprinkler system. Check for leaks around the new head and riser. Adjust the sprinkler head to ensure it sprays in the desired direction.

Tip: If the sprinkler head isn’t rotating or has a poor spray pattern, disassemble it and clean the filter. Replace the filter if necessary.

By following these steps, you can effectively fix common issues with your lawn sprinklers. Next, we’ll cover how to fix specific problems like non-rotating heads and damaged water lines.
