Inspecting and Repairing the Valves

The Elixir of a Flawless Sprinkler System In the intricate dance of your sprinkler system, valves hold the key to a harmonious performance. They dictate the ebb and flow of water, orchestrating the symphony of hydration for your beloved garden. But, like any maestro, valves can sometimes stumble, disrupting the rhythm and causing a disheartening water wastage.

Look for the telltale signs of valve glitches – the irregular water pressure, the persistent leaks, or the zones that refuse to yield to your command. These are the breadcrumbs that lead you to the heart of the malfunction. The culprits behind valve malfunctions are often as mundane as they are persistent.

Debris, like a mischievous troupe of intruders, can accumulate and clog the delicate workings of the valve. Worn-out seals or diaphragms, weary from their duties, may falter and fail. And the fickle mistress of electricity can bestow her capricious blessings upon the solenoid, leaving it with loose connections or electrical faults.

Yet fear not, for the remedy lies within your grasp. Silence the flow of water, and venture into the inner sanctum of the valve by removing its bonnet. With meticulous care, purge the debris that has taken refuge within, and replace any damaged seals or diaphragms.

Pay homage to the solenoid, tightening loose connections and banishing electrical maladies. But this is not a one-time affair; it is a dance of persistence. Regular maintenance is the key, the secret to everlasting harmony.

Watch for leaks, for they are the whispers of impending trouble. Clean the valves, removing the vestiges of dirt and grime that threaten their efficiency. And spare a thought for the controller, the mastermind behind it all, as it oversees the valves and the grand tapestry they weave.

In this delicate ballet, where valves reign supreme, your vigilance is rewarded. By tending to their needs, by nurturing and caring for their every whim, you ensure an opus of optimal performance. Your sprinkler system, once plagued by frustration, will flourish under your loving touch.

And in the emerald embrace of your well-tended lawn, gratitude shall bloom.

Why do my sprinklers stay on even though the controller is off?

If your controller is turned off but the water continues to run, it indicates a problem with one or all of the valves or supply lines. In such cases, you might need to clean or replace a valve, or you may want to consider calling a contractor for assistance.

Why is my sprinkler stuck?

The main reason why a sprinkler head gets stuck is because of dirt and debris. When dirt, rocks, leaves, or grass become trapped between the sprinkler body and the riser, it can block the movement and prevent the riser from going back into the body. As a result, the sprinkler head remains raised and won’t go down.

Why does my Rainbird keep running?

One possible reason for a program repeating is if there is a second start time set. The start times determine the specific time when your ESP-Me timer will start watering and also determine how many times a day the timer will water. It’s important to note that the ESP-Me allows you to set up to 6 start times per program.
