Lawn Irrigation System Inspection Course

Inspection & Writing Assignment:

This is a picture of a tilted sprinkler head. Leaning sprinkler heads do not get the proper coverage they should be getting. This head is also actually touching the home causing a lot of moisture accumulation against the walls. Lastly, the head is also rotated so that it sprays directly against the house and patio. Not seen in this picture is a patio handrail that is damaged and rusted by the water over spray.

According to the article about lawn sprinklers causing wood decks and balconies to decay, home inspectors must observe how the “head to head coverage” affects surrounding wooden objects. Fungi is the main source of wood decay and any object that has a Fiber Saturation Point between 27-30% is capable of fungi growth. Privacy fences, wooden decks and sheds must be observed to know if the “head to head” coverage will cause conducive conditions for wood destroying organisms.

A broken sprinkler head can happen from a few different things. This sprinkler head could have been ran over by a lawn mower or the water line under the soil could have cracked or become loose from the bottom of the sprinkler head. This could be a easy fix from an irrigation specialist.

Irrigation Inspection

This is a valve in my yard that supplies the green house drip lines. There are no cracks in the piping or leaks into the box. The wires all seem to be in well working condition. I did notice though, that the sprinkler head right next to the box is unlevel and will need to be fixed.

This section made me think about a lot of stuff about the house in Utah I recently sold. I owned it for 4 years and in that time, I was constantly fighting the even distribution of my lawn. Misting sprinklers, mismatched heads, even melted heads. I was always replacing heads and repositioning them. It was a constant nightmare that possibly could’ve been avoided had I had just a little more knowledge such as what I found in this section.

This sub-zone control is located underground in an appropriate housing (box) and controls 2 zones. The newer Toro 12 v digital control is programable for time/day/month run times.This pic shows the controler and the solenoids and the in/out distribution piping.

Research & Writing Assignment:

Using the drawing of Lawn Sprinkler Contributing To Post Decay, it is apparent that there are some defects present.
First there is probably no need for the sprinkler head to provide water coverage under the deck at all, as with no sunlight it can only cause retained moisture.
Secondly the regular water spray on to the post supporting the deck will contribute to its eventual rot, causing a potential safety issue with the deck support.

Inspecting the soil
There appeared to be evidence of deep rich soil. With further inspection there were no differences in lawn thickness. No area’s were more lush and rich or more sunken down than another. I see no evidence of any line breaks. Because it is still early in the season the sprinkler system was not operational therefore I was unable to fully inspect this system. Recommend further evaluation by a qualified professional.

This picture gives a really nice break down of the home irrigation system. As part of this system is the bonnet and atmospheric vacuum breaker. This is a very important function because this system prevents contaminated water from being drawn up into the domestic water supply.

Getting ready to start the course. In my area of Florida, houses are few and far between that don’t have a sprinkler system.
