If you're going to have a residential sprinkler system in your yard, it's a good idea to familiarize yourself with some of the issues you might face. As with anything with moving parts in such an environment, sprinklers will have a few issues over the course of their life. Luckily, most of these problems can be easily fixed if you have the right tools and the right skills.
Damaged Spray Head
Damaged spray heads are not uncommon, especially if you've recently mowed your lawn or driven a vehicle over it. Any significant force applied to the spray head can damage it. In this case, you'll know something is wrong since the sprinkler head may not pop up or it may start spraying water everywhere.
The solution to this problem is usually to replace the damaged spray head. However, a sprinkler head not popping up could also be caused by low water pressure.
Blocked Sprinkler Heads
Dirt and other debris can enter the nozzles in the sprinkler head and clog them. This can also be caused by a clogged filter in the sprinkler head, which could be due to minerals in the water. You'll need to remove the nozzle and filter and give them a thorough cleaning.
You can tell if the sprinkler head is clogged if you notice an uneven or interrupted spray. Sometimes there won't be any water at all.
If your sprinkler is still running even after you turn it off, a stuck valve is a likely culprit. These valves can be prevented from closing by a small rock or a piece of debris that was thrown while mowing the lawn. The typical sprinklers used in homes have two valves. You should check both valves to find out which one is affected.
This problem can be solved by removing the solenoid and letting some water run through, or you may have to remove the project manually.
Buzzing Sound When Running
Regular sprinklers should be quiet when operating. If you hear a buzzing sound coming from the sprinkler, this means that the relay needs replacing. The relay is a switch used by sprinklers that can become less effective with time. Climates with a lot of salt can result in a shorter lifespan for your sprinkler's relay.
Replacing a relay can be dangerous since this is an electrical component. This is a job you should probably leave to a sprinkler repair expert.Share
