Ok, here is the anticipated blog about irrigation systems. Now some folks that have snow are probably shaking there heads. But in the warm south its getting warmer and people are already cutting their grass, me. So lets begin.
When we have an irrigation system installed at our homes there is a lot to consider from planning to maintenance of the systems. What we want to talk about is the heads, the pump, and also some facts about the maintenance. When we are having our systems come on, you will see one zone come on for about 3-5 minutes. Depending on the type of pump, will determine how many heads will be per zone. Older systems are 1-2 heads and newer can be up to 5. But you never want to have more than one zone come on at a time.
The heads are your main maintenance items. Dirt, lawn mowers and animals can be a contributor to why these items some times do goofy things. For example, its best to maybe have a donut around the head so the lawn guy does not run over them. Its best to have them clean every so often. Especially the directional head types. If they can not spray then its defeating the purpose of the head. Now on a different note, many irrigation contractors place the heads near equipment, (the hvac unit) and even though it may be a directional head some are not. This will cause the unit to prematurely fail. I always recommend the heads to be about 3-5 feet away from the units.
Next we have the pump. The pump can be in the ground or above depending upon the system. However, you do not want the box that houses the pump above ground. The pump connects to the manifold which controls the system. You will see the system is light gauge wiring and wire nuts. The wire nuts are not the typical ones you buy a bag for $3.00 at the local store. They are water proof. They have silicone in them to protect the wires. Make sure that you have these. Most systems fail because of improper materials.
And lastly, the brain of the system. The timer or some call the clock. The clock will control the zones from the mainifold. The clock will also allow you to turn on a zone buy it self. For example, if you just planted a new bush or flowers and want to water them after planting. You can also program the time you want to come on. For many, the times are usually 5 am and 8 pm. Just before and after the sun.
So, I hope this may explain a bit of the irrigation system and few maintenance items. If you have any questions feel free to contact us anytime. 352-322-2700 or www. emeraldinspectionservice.com
