Sprinkler Repair and Sprinkler Systems

Owners of lawn irrigation sprinkler systems may encounter five potential problems with their systems that require sprinkler repair. These potential problems are broken heads, stuck valves, uneven precipitation, broken pipe, and wiring problems. Some minor problems can be fixed by the owner such as broken heads or stuck valves. However, it may require a more experienced professional to fix wiring problems, uneven precipitation or broken pipes.

Sprinkler Heads

Sprinkler heads wear out over time or can be broken by mower blades or snow shovels. The quickest way to fix them is by unscrewing the stem from the canister, then screwing a new stem in its place. If you want to help avoid the new head being broken by mower blades, it is suggested that you dig a deeper hole to place it in so it will be lower than the blade. Cut a shallow square of sod around the head. Move the soil around the head. The top of the head should sit approximately one-half inch above the soil. If it’s any deeper, it will pick up debris that can damage its seal. If you place it higher, it might get struck by mower blades the next time you mow. Be sure to tamp the soil firmly so the head will not resurface over time. As with anything, be sure to follow manufacturer instructions.

Sprinkler Valves

Sprinkler repair often means checking for stuck valves. A sure sign that your sprinkler valves may be stuck is when a zone of sprinklers runs nonstop while your controller is in the off position. A small rock or other debris could be preventing the valve from fully closing. In order to fix a stuck valve, you can try to take some pressure off the diaphragm by unscrewing the solenoid. After letting some water pass through the valve, you can screw the solenoid back on. The valve should seal properly in the off position, if not, it is stuck open and you will have to remove the top. After removing the top, check for debris, you might need a pair of tweezers for small items. If your problem is not fixed and you didn’t find any debris, your diaphragm may be damaged or worn out and needs to be replaced.
