Remember, addressing leaks promptly can prevent further damage to your lawn and save you money on wasted water bills. Keep an eye out for any signs of leaks and take action as soon as possible.

Repairing crushed pipes

Repairing crushed pipes is a common issue that can cause low water pressure and inefficient irrigation. If you notice areas of your lawn not receiving sufficient water, it’s possible that one or more pipes have been damaged or crushed.

To troubleshoot this problem, start by visually inspecting the area where the pipes are located. Look for signs of physical damage such as dents, kinks, or visible leaks. If you find any crushed pipes, you’ll need to carefully excavate around them to expose the damaged section. Once exposed, cut out the damaged portion using a pipe cutter and replace it with a new section of pipe using appropriate connectors and fittings.

Remember to always turn off the water supply before attempting any repairs and ensure that all connections are secure to prevent future issues. By addressing crushed pipes promptly, you can restore proper water flow to your irrigation system and keep your lawn looking lush and healthy.

Checking the valves

Checking the valves is an important step when troubleshooting issues with your lawn irrigation system. Valves control the flow of water to each zone, and if they are not functioning properly, it can lead to problems like low water pressure or inactive zones.

To check the valves, start by locating the main valve box. Open it up and inspect each valve for any signs of damage or leaks. Make sure all the valves are in the correct position – open or closed – according to your watering schedule.

Next, test each valve by manually turning them on and off using the control lever or knob. Listen for any unusual sounds or vibrations that could indicate a problem with the valve’s internal components. If you notice any issues, such as a stuck or faulty valve, it may need to be replaced.
