When Should I Turn My Sprinkler System Back On in Spring in Oklahoma?

For Bermuda and Zoysia lawns — which make up the majority of residential turf in the Tulsa area — the right time to start regular irrigation in spring is mid-April to early May, after the final frost risk has passed and soil temperatures have reached 60 degrees Fahrenheit consistently. Starting your irrigation system earlier than […]

How Do I Winterize My Sprinkler System in Tulsa?

Winterizing a Tulsa-area irrigation system means purging the zone lines with compressed air to remove the water that would otherwise freeze and crack PVC pipe and fittings, protecting the above-grade backflow preventer from freeze damage, and closing the irrigation supply valve for the season. The standard approach is a blowout winterization performed in late October […]

What Causes Water Hammer Noise When My Sprinklers Turn On?

Water hammer in irrigation systems is caused by a sudden pressure wave moving through the pipe when water velocity changes abruptly — typically when a zone valve opens or closes rapidly and the moving water has nowhere to go in the instant the flow is interrupted or started. The result is a thud, bang, or […]

How Do I Find a Water Leak in My Underground Sprinkler Line?

Finding an underground sprinkler line leak starts with isolating which zone is losing water, then walking the pipe path for that zone while it runs and looking for surface signs — soft or soggy ground, water bubbling up through turf, unexplained wet spots, or a distinctly greener stripe of grass growing over the leak point. […]

How Do I Locate My Buried Sprinkler Valve Boxes?

The most reliable way to locate buried sprinkler valve boxes is to trace the low-voltage wiring from the irrigation controller back to each valve. Every zone valve is connected by a two-wire circuit — a common wire and a zone wire — that runs from the controller terminal strip out to the valve location underground. […]

Why Does Water Keep Running After My Sprinkler Zone Shuts Off?

Water continuing after a zone shuts off is almost always one of two things: low-head drainage or a stuck-open zone valve. Low-head drainage is not a system failure — it is gravity moving water through the lowest sprinkler heads on a sloped zone circuit after the valve closes, and it stops on its own within […]

Why Won’t One Zone Turn On Even Though the Controller Is Working?

When a single irrigation zone fails to run while the rest of the system works normally, the problem is almost always in one of three places: the solenoid on the zone valve, the low-voltage wiring between the controller and that valve, or the controller terminal for that specific zone. Because all other zones are functioning, […]

The short answer: Pull up the pop-up stem, unscrew or pull off the nozzle, rinse it under water, and use a small pin or paperclip to clear debris from the opening. For spray head nozzles, twist counterclockwise to remove. For rotors, pry up the rubber nozzle cover and lift out the nozzle insert. Flush the […]
