As sprinkler repair experts, a frequent problem we see pretty promptly in dry climates can be a faulty valve. This article describes how most effective to diagnose and repair a faulty valve by replacing a failed solenoid. Though electrical components are relatively trustworthy, a prevalent point of failure could be the solenoid. The purpose for this really is that a solenoid is each an electrical and mechanical device. A fixed wire coil surrounds a mechanical piston, and when an electrical present is applied towards the coil, a temporary magnetic field is designed which induces motion inside the piston. This motion from the piston is made use of to mechanically open and close the water valve. Get additional information about sprinkler repair garland
Right here is often a tip on tips on how to diagnose a faulty solenoid. In dry climates, like the Dallas Metroplex, or in the course of periods of small rain, one section or zone of a sprinkler system will look distinct to the other zones. Either the sprinklers in that zone won’t switch on, or they will be on continuously. Solenoid failure has the symptom of a valve becoming inoperative, either remaining inside the closed position, or remaining inside the open position. Generally this will disable an entire sprinkler zone, so is normally simple to diagnose. This is a common sprinkler repair.
Replacement solenoids are out there for most valves, and it truly is a reasonably straightforward job to replace one. Here can be a tip ahead of beginning the job: be sure you have identified the precise make and model of your valve, as there are plenty of variations of solenoids that are incompatible. Check along with your sprinkler repair company or hardware store that an exact replacement is accessible ahead of starting work. The only tools needed are a pair of wire cutters plus a pair of pliers.
Essential advice: ensure that the principle water supply to the sprinkler system is turned off, as removing the solenoid signifies the valve will likely be fully open at that time, and water will shoot up via the solenoid body if not turned off. Tip: generally the shutoff is either located near the primary home supply, or next for the key valve box, so look in those two locations very first. Once the water is turned off, assuming the faulty valve has been identified, the repair can commence. With a pair of wire cutters, cut the 2 wires going for the solenoid. It might be tempting to just disconnect the existing screw connectors that are near the valve, but these are often corroded and it truly is much better to produce a clean-cut.
As soon as the solenoid is free of charge in the existing wires, it can be removed by turning it counter-clockwise, as well as the new solenoid installed by turning it clockwise. Guarantee it is tight enough for a water-tight seal. After installed, strip about half an inch of insulation back from every single on the provide wires and use a fresh screw nut to connect the solenoid. There are two wires to be connected, the provide wire along with the popular wire. The typical wire is typically white to produce it simpler to determine.
Right here is some crucial info that will prevent complications taking place some time later (following this assistance will cost a few dollars much more right now, but can save complicated troubles later on): As soon as the connections are tight ensure that to often use a particular water-tight cap over the connections. Sprinkler grease caps are out there from regional sprinkler supply retailers. These caps are plastic tubes filled with grease; the connectors are pushed in to the grease, and also the folding top rated snapped down. This guarantees the connectors are surrounded by grease, which prevents water entry and corrosion. This simple and inexpensive step will help avert intermittent problems resulting from corrosion occurring later. Once the grease caps are closed, the solenoid sprinkler repair is full.
In a dry climate, make sure that any grass that was broken by an inoperative solenoid valve receives adequate watering to recover, prior to returning the watering schedule to its typical setting. In wetter climates, it might be possible to just resume standard watering.
