Maintenance, Repair and Tune-Up Services for Sprinkler Irrigation Systems

Starting at $50.00* (up to 6 irrigation zones)

Absolute Irrigation provides quality install and repair service for the Bluffton, Hilton Head*, Okatie and surrounding areas.

Every spring, homeowners turn on their irrigation system hoping that everything is working just as it did the previous fall. As quickly as a sprinkler head doesn’t pop up right, or rotor head doesn’t turn correctly, or worse, there is no power to the sprinklers, it’s time for you to call in the experts.

Don’t wait until you notice a problem. Your sprinkler system and irrigation needs to be properly tuned and checked before trying to water any part of your landscape. Our sprinkler technician has been trained to use a system of checks and testing to ensure your sprinklers, controller box, timer, valve zones, and circuits are all working as they should.

Our Irrigation Tune-Up Process

  • Inspect the irrigation system for any wet spots in the lawn or leaks around the spray heads and rotors.
  • Check for sprinkler heads that are bent or laying over, cracks or damage.
  • Check for any broken, malfunctioning or cracked sprinkler heads or nozzles.
  • Adjust all spray type sprinklers and test spray patterns to ensure optimal coverage.
  • Clean and adjust all rotor-type sprinklers, testing for total coverage to make sure there are no dry spots.
  • Investigate for wet spots, dry spots and leaks.
  • Ensure all zones are working by checking each station zone by zone.
  • Identify all heads that are in need of being raised or lowered.
  • Examine rain and freeze sensor for proper operation.
  • Set controller for proper settings based on weather conditions and the season.
  • Make recommendations for repairs or improvements.

After we’ve done a full checkup and performed any necessary sprinkler maintenance on your system, we’ll run it through several cycles. We want to make sure it’s still maintaining proper water pressure, and that all the zones in the system are performing exactly as they’re supposed to.

If we find that your sprinkler system is demonstrating intermittent problems, we’ll immediately diagnose the issue and provide you an estimate on any necessary sprinkler system repair.

A good irrigation system is vital to having a beautiful lawn so do not run a dormant sprinkler system before having it properly inspected and checked. Call us for all your maintenance and tune-ups for your sprinklers and irrigation system.  You will be surprised how much money and time you’ll save by having an expert technician service your system.

* Most systems are 6 zones or less. Call for price if you have a 7+ zone irrigation system. Estimate is for all of Bluffton. For Hilton Head residents, please add transportation fee of $20.

How To Water Your Lawn

How much should you water?  How often?  Proper watering is crucial to having the best-looking lawn on the block.  Here are some key points:

  • Your lawn needs at least 1”-1 ½” of water per week, year-round, during the winter, too.
  • Water deeply 2-3 times per week, rather than daily.
  • Water as early in the morning as you can, when possible.
  • If you can’t push a 6” screwdriver into your lawn, you’re not watering enough.
  • You will need to water more in the heat, especially if you have a fescue lawn.
  • Don’t water so long that it runs down the street.
  • If you have automatic sprinklers, check them regularly to be sure you’re getting complete coverage.
  • If a brown area doesn’t respond to watering, look for another problem.

Let’s go over these points.

Your lawn needs at least 1″-1 ½ ” of water per week, year-round, during the winter, too.  Lawns that are dry going into winter or during winter are more stressed and more likely to sustain winter damage. How do you know how much you’re getting?  First of all, buy a rain gauge.  If you get an inch of water in it per week, you’re cool.  If you don’t, you need to water.  (Bad news, if you live in Oklahoma.  Our precipitation comes when we don’t need it – like when it’s -13°, never when it’s 100°.)

How long should you set your sprinklers to get one inch?  We can’t tell you that, because we don’t know what kind of sprinkler you have or what your water pressure is like.  With automatic sprinklers, it’s usually one hour.   But you can measure that yourself.  Just get a tuna can, which is 1” tall, (eat the tuna out of it, first) and place it where your sprinkler is hitting.  Run your sprinkler and see how long it takes to get a half inch of water in the can – just like a rain gauge.  Usually it’s about 30 minutes.   So 20 minutes, 3 times per week will get an inch of water on your lawn, and 30 minutes 3 times per week will get 1 ½” down.  Bear in mind that during extreme heat, you will need to water more, due to evaporation and heat stress on the grass.

Water deeply 2-3 times per week, rather than daily.  Watering daily will give your grass a shallow root system.  Shallow root systems dry out fast and weaken your turf.  Watering deeply 3 times per week will give your grass a deep root system, making it stronger and more drought-resistant.

Set your irrigation system to water as early in the morning as you can, when possible.  Watering early in the morning will ensure that your lawn dries completely before nightfall.  A wet lawn at night, on a regular basis, can lead to fungus and disease problems.  Also, it’s cooler and less windy in the morning, so you have less evaporation, which will save money on your water bill and take less time to get the water on your lawn.  If morning watering is impossible, watering at any time is always better than not watering at all!

If you can’t push a 6” screwdriver into your lawn, you’re not watering enough.  Watering 1″-1 ½ ” per week is a guideline.  Different soil types need different amounts.  Soil is rarely composed of one type, but rather a combination of clay and sand, which makes loam.  A sandy loam won’t hold moisture as well as a clayish-loam.  Clay holds moisture better (think mud,) but the water is slow to penetrate it.  You can tell what your dominant type of soil is by getting a moist handful and squeezing it.  Clay will smush into a ball that doesn’t fall apart.  Sand will stick together when squeezed, but not for very long.  In Oklahoma, our soil is mainly on the clay side, unless you’re by a river, and then it leans toward sand.  High winds also dry out your lawn incredibly fast.

You will need to water more in the heat, especially if you have a fescue lawn.  You may need to water more in the summer heat to keep your lawn from becoming drought-stressed, especially if high temps are accompanied by high winds.  If we have extreme temperatures – high 90’s and over 100º – for a prolonged time period, you might want to 1) raise your mowing height a little 2) water lightly daily to cool off the grass (this is especially true for fescue.)  Grass needs more water during the heat because it also uses water as an internal coolant.  Daily waterings in the heat should be in addition to your regular deep waterings.

Don’t water so long that it runs down the street.  If water starts running down the street before you get your half inch on there, turn off the water and wait for it to soak in, then resume watering.  This might happen if you haven’t had time to water for a while.  If it happens every time you water, either you’re waiting too long in-between waterings, or you may have a compaction problem.  Compaction occurs in heavy clay soil or in high traffic areas.  Aeration may alleviate the problem temporarily, but usually you have to change the conditions causing the compaction for long-term relief.  You might want to consider an application of an environmentally-friendly, liquid aeration. It’s the same price as your regular application price, so just let us know if you’d like it – see the liquid aeration page here.

If you have automatic sprinklers, check them regularly to be sure you’re getting complete coverage.   Have you ever driven by a neighborhood entrance or along a business with nice landscaping that has this one sprinkler head aimed out at the street, and every day it’s on, spraying in the street, even if it’s raining – even if it’s freezing cold, and it’s making a nice icy spot on the road?  Watch your sprinklers every once in a while to be sure you don’t have one like that!

If a brown area doesn’t respond to watering, look for another problem.  Assuming your sprinkler coverage is adequate, you might have a fungus, army worms, spring dead spot, chinch bugs, construction debris buried a foot under the soil, or any number of problems that mimic drought stress.  Take a closer look, or call us to come out and look at it.
