Small irrigation problems can become expensive repairs when they are ignored through a Long Island winter. A damaged head, slow leak or valve problem may continue wasting water during the season and can worsen when temperatures fall.

Homeowners in Nassau County, Queens and western Suffolk should look for these seven warning signs before shutting the system down for the year.

1. A sprinkler zone will not turn on

A zone that does not run may have a controller, wiring, solenoid or valve problem. Winterizing a nonworking zone without diagnosing it can leave water trapped in part of the system.

2. Water pools around a sprinkler head

Standing water can point to a cracked fitting, damaged riser, leaking valve or low head drainage. The source should be identified before the ground freezes.

3. Dry areas appear beside overly wet areas

Uneven watering commonly results from clogged nozzles, poor head alignment, pressure problems or changes to the landscape. A professional coverage check can determine whether adjustment, repair or a zone modification is appropriate.

4. Heads do not rise or retract properly

Dirt, turf growth and internal wear can keep spray heads from operating correctly. Heads left raised are especially vulnerable to lawn equipment and foot traffic.

5. The controller behaves unpredictably

Programs that reset, zones that run at the wrong time or a blank display may indicate power, wiring or controller failure. This may also be a good time to consider a Bee-Hyve or compatible smart-controller upgrade.

6. Water pressure has changed

Low pressure may cause poor coverage, while excessive pressure can create misting and component wear. Pressure changes can also signal a leak or partially closed valve.

7. Your water bill increased unexpectedly

An underground irrigation leak is not always visible. Comparing water use and inspecting each zone can help isolate a problem before it becomes larger.

Repair first, then winterize

Winterization protects a functioning system; it does not correct broken parts. Documenting and repairing problems before the blowout makes spring startup easier and reduces unpleasant surprises.
