A sprinkler system can be a real boon for a homeowner, but in order to get the best results, you need to make sure that you take good care of your system. While it should be obvious when your sprinkler system is not running at all, diagnosing when your system is not running as well as it should can be trickier. You may see dry spots in your lawn, but knowing what is causing the dry spots may be less obvious. Knowing exactly what to look for is the key to improving the function of your system. 

Vertical Is the Best

Sprinkler installers should make sure that your sprinkler heads are in a ground so that they are straight up and down. On the other hand, if you have a sloppy installation job, or the ground shifts over time, your heads tilt. In this case, the heads will shoot water up into the air on one side and into the ground on the other. When this happens, you will not get the kind of the coverage that you should and dry spots are the natural result. To correct the coverage, you carefully need to dig around the head with a garden trowel, straighten the head, and then repack the dirt around the head. 

Sticky Valves

Sprinkler valves can get dirty and when they do, they can either refuse to open or refuse to close like they should. If they refuse to close, the zone that the valve governs will remain open, and you can end up with a flooded yard. If they refuse to open, you will end up with a dry spot for the valve's zone. In order to fix a sticky valve, you need to screw off the valve's collar, remove the gunk, rinse off the valve diaphragm, then put the valve back together. The diaphragm is a rubber disk, so it should be easy enough to spot when you take the valve apart. 

Small problems like a few grains of sand on a diaphragm or a slightly tilted sprinkler head can cause serious problems for lawn sprinklers. Luckily small problems are also easy to fix. While you should be able to do some maintenance for your sprinkler system on your own, if for any reason, you feel like you can't work on your sprinkler system on your own, you should call a sprinkler repair professional for help.
