Why Is My Sprinkler System Losing Pressure? A Bloomfield Hills Homeowner’s Guide

Low sprinkler pressure is one of the most common irrigation complaints in Bloomfield Hills and surrounding Oakland County communities. A weak zone does not automatically mean you need a new irrigation system. In many cases, the cause is a repairable leak, valve problem, clogged nozzle, damaged head, or controller issue.

Start by checking whether one zone or the whole system is affected

If only one zone has weak pressure, the problem is often located somewhere within that zone. Look for heads that barely rise, unusually wet areas, bubbling water, or a section of lawn that is much greener than the surrounding turf. These clues can point toward an underground leak or damaged fitting.

If every zone is weak, the cause may be closer to the water supply, shutoff, backflow assembly, master valve, or another system-wide component.

Common causes of low sprinkler pressure

• Broken or cracked sprinkler heads
• Underground lateral-line leaks
• Partially closed irrigation shutoff valves
• Valve or solenoid problems
• Clogged nozzles or filters
• Too many heads operating on one zone
• Changes in available water pressure

Why wet spots matter

A soggy area that appears while a particular zone is running is an important diagnostic clue. Water may be escaping underground instead of reaching the sprinkler heads. Because buried leaks are not always visible at the surface, technicians often compare head performance, valve operation, and unusually wet areas to narrow down the location.

When to call for sprinkler repair

If multiple heads stay down, a zone will not operate correctly, water is surfacing from the lawn, or troubleshooting the controller does not solve the problem, professional diagnosis can prevent wasted water and additional lawn damage.
