The water spray from the sprinkler system should be re-directed away from the structure and/or any fencing, decks, etc., to decrease the possibility of damage and decay over time. Damaged and / or decayed materials can increase the potential for insect infestation.
For this assignment, I chose a pic from one of my first paid inspections. A cracked manifold in the irrigation system was leaking steadily near the home’s foundation. This wasn’t visible except for the ponding found at the sump pump terminus. Leaking water from the manifold was filling the sump pit and creating a muddy area on the other side of the house.

Recently I inspected a home with an irrigation system that had 9 zones (the home was less than 3000 sq. ft.). I found that two of the zones had damaged heads as indicated in the picture. Among that, several heads did not recede when the zone was shut off.
I read a few riddles that were pretty cool. I really like riddle #4 which talks about the GFCI lol. I can now add a little humor to my networking which will prove that we inspectors can have a good time too!
When inspecting the lawn irrigation system you need to be familiar with the whole system or the connecting devices. You should know that the system starts after the water meter. The water line runs to the back-flow prevention device which is connected to the irrigation valves. The irrigation controller is the brains of the whole system which is connected to the irrigation valves with electrical wiring. Also water lines are connected to the irrigation valves which run to different areas/zones of the property with heads connected that spray the water on the lawn.
When inspecting the attic access ladder make sure the proper fasteners have been used. Also there needs to be the proper amount of fasteners used. The manufacturers instructions will have this information. Look for structural problems with the attic access ladders, such as loose mounting bolts, ladder cut to short or to long. Look for any cracks in wooden attic access ladders.

Multiple sprinkler heads were damaged and needed repair and replacement by a qualified landscape contractor at the time of the inspection. A few examples were sprinkler heads at the right side spraying the sidewalk that should be disabled. A few heads spraying the right and left side of the home.
When inspecting a sprinkler system with a deck on the home we verify that all sprinkler heads have been removed from under the deck if this appears to have been recently added. And to verify that all sprinkler heads do not spray onto any portion of the deck.
This spray head is a high pressure spray head that is receiving inadequate water pressure. This could be caused by either faulty spray head, a break or crack in the supply line or by a faulty control valve. Recommend that a qualified irrigation contractor repair or replace the line, valve, or spray as necessary.
A lawn irrigation system inspection is a visual inspection of the components of the system and the proper operation of the system. Some of the limitations or restrictions of this type of inspection can include any or all of the following: no water to the system, no power to the system, or water valves or control valves in the off position.
Irrigation systems consist of many different parts which include a main water source, shut off valve, a drain valve to winterize the system, backflow preventer or vacuum breaker, covered valve box with electronic valves for each zone, clock or timer to control the zones, lateral piping to each zone and the sprinkler heads themselves. There also may be a pressure reducer to drip zones.
This is a modern sprinkler controller with a wireless rain freeze sensor. This controller by Hunter is modular and can be expanded by adding modules to the controller to expand the controller in increments of three. This controller can have multiple watering programs which can be scheduled to water different times a day. The controller also be set to adjust the watering programs based on seasonal changes. The rain freeze sensor will keep the controller from watering when it rains or in the event of freezing water.
When inspecting decks the inspector should check to see if sprinkler heads spray on the deck posts Sprinkler heads spraying regularly on deck posts can lead to premature deterioration and failure of the post. Inspector should inform the buyer of this condition and suggest regular monitoring and maintenance of the affected posts.
Control valve (front lawn zone 1) not operating correctly, does not open when activated by irrigation clock. Inspection of power lines from clock to valve, wires show signs of repair, defective, and sections of wire above ground. There is no voltage from clock to valve when activated, replacement of power cable recommended.
Picture of lawn with obvious deeper green color in center of lawn where there is a slight depression. This was automatically thought of as a underground leak in the system or greener area getting more water than other areas of lawn. Learned to look at soil conditions as the greener area may be getting organic materials from run-off and grass is greener due to having better nutrients from these organic materials.
I wanted to learn more about vacuum breakers and understand how they worked better. I basically learned that the main important thing about them is that they prevents bad water from being siphoned through into drinking water or water to be used in the home.
I investigated lawn irrigation systems to see how they worked and wanted to understand what double check valves and atmospheric vacuum breakers did. I learned about valve systems and how water pressures can affect how well these lawn systems work.
