Low water pressure in lawn sprinkler zones can be frustrating and leads to unhealthy lawns. Here are a few helpful steps to identify and fix the problem. It’s best to call a professional like the Sprinkler Doctor if these steps don’t fix the problem.
First, inspect the sprinkler heads for any damage. Replacing or cleaning the sprinkler head is essential if you see any visible damage or obstruction. A damaged or clogged sprinkler head can cause low water pressure.
Next, check the water supply line leading to the sprinkler zone. If other lawn areas are experiencing normal water pressure or flow, there may be a blockage or leak in the supply line leading to the low-pressure zone.
Carefully examine the supply lines and fix any visible leaks or blockages.
If the supply line looks fine, look for any valves that have been partially closed or restricted. A partially closed valve can reduce water pressure in the sprinkler zone. Look for and open any valves that may have been accidentally closed.
Another cause of low water pressure in lawn sprinklers is an overly high number of sprayers, pipes, or heads on the line, all trying to run simultaneously. See if the problem zone exceeds the operating capacity of its water line. Consider splitting the zone into smaller parts and running them in staggered cycles.
Lastly, consider replacing the irrigation system’s water regulator. These devices can become worn over time, reducing water pressure on your lawn. Look for and replace any faulty regulators.
Following these simple steps, you can diagnose and fix a low-pressure lawn sprinkler zone, ensuring a lush and healthy lawn all year round. Regularly scheduled maintenance checks can highlight problems early on and save you time, money, and effort in the long run.
