Tune-up Your Irrigation System

Watering no more than is necessary saves you money by lowering your water bill, is better for your plants, and helps protect the environment from unnecessary runoff and the pollutants that tend to go with the runoff, such as fertilizer and herbicides.  One of the easiest and most effective ways to reduce landscape water use is to make simple adjustments and repairs to your irrigation system on a regular basis.

Frequency
:
once every other week to once per month.
Time required: the first time you tune up the irrigation system it could take a while if you have an irrigation system in really bad shape, with leaks and that sort of thing;  but, of course, if your irrigation system is not in good shape then you also have the most to gain from the tune-up in terms of water savings.  Once you get the system tuned-up, regular monthly adjustments usually take no more than 5 to 10 minutes.
 
With your Sprinkler System on:

1.  Adjust pressureMost sprinklers are made to operate at about 35 psi (pounds per square inch); but most home water systems operate at 65 psi or greater.  A sign that you might have too much pressure at the sprinkler head is when the water blowing out of the sprinkler turns into a mist - is atomized.  The atomized water is easily blown away by the slightest breeze and is also quickly evaporated before reaching the ground and the plant material.  Adjust the pressure to the sprinkler system if possible; this may require purchasing and installing a pressure regulator.
2.  Repair water lines: Look for and repair leaks in the irrigation line.  If you are handy, you can fix the leaks yourself; otherwise, you may want to pay a gardener to do the work.  This type of work is usually not difficult and is covered in most do-it-yourself home repair guides.

3.  Repair sprinkler heads: Look for and fix sprinkler heads that don't pop up, are clogged or otherwise not working properly. For example, you may have to cut grass blocking the heads, or remove the head and clean it out.

4.  Redirect spray back onto landscape: Over time, sprinkler heads often get turned slightly, so they end up watering the street or sidewalk rather than the landscape.  Turn the sprinkler head if it has been turned too far to one side or the other.

5.  Adjust Distance of spray: Experts look for head-to-head coverage, meaning the spray from one sprinkler reaches the sprinklers on either side of it. If the irrigation system was designed and installed correctly, this will result in very even distribution of the water. For example, if your sprinklers are 8 feet apart, each sprinkler should be spraying 8 feet in each direction. If you are not getting head-to-head coverage and you have adjustable-type sprinkler heads, you can reduce water use and/or improve plant conditions by adjusting the distance of the spray.
 

6.  Replace spray heads with stream nozzles: Many of the newer sprinkler heads shoot the water out in a stream rather than in a fan-spray fashion.  The stream conserves water because the droplets are larger (less water blown away in the breeze or evaporated) and less water is emitted per minutes (reducing runoff by giving the water time to soak into the ground).  Consider replacing your existing spray heads with stream nozzles.

7.  Adjust irrigation controller: After tuning-up your irrigation system, adjust the irrigation controller if you have one, adding more or less water depending on the needs of your plants.
