How Much Does A Lawn Sprinkler System Cost?
Sprinkler System Prices
Ground Sprinkler System Costs
The cost to install an underground sprinkler system varies slightly from region to region, but depends on two main factors: the size of the lawn (the amount of pipe and number of sprinkler heads needed) and the quality of the parts used. That being said, for an average sized 2,500 square foot lawn, an average price range is from $2,000 to $3,000.
Another way to estimate the cost of a sprinkler system is to price it by zone. A zone is an area in which 5-10 lawn sprinkler heads are concentrated and run at one time, and costs in the neighborhood of $400-$600 apiece. (Note: only one zone operates at a time because it requires a lot of water-somewhere around 20 gallons per minute)
Keep in mind that a larger lawn isnít proportionally more expensive, because once the plumbing, which is the most complicated step, is installed and connected, it is easy to add more zones. So, while a 2,500 square foot lawn may average $2500, a 3500 square foot lawn may only be $3000 to $4000.
A lawn sprinkler system consists of several main components. The controller is a small computer that is installed in an out of the way place such as the garage. It controls all the timing of the in ground sprinkler system, including which zone turns on when and for how long. The controller is linked to a valve system that controls the water flow into the sprinkler system zones. The valves are buried underground in boxes that make them easy to access if needed. The water then runs through PVC piping buried a foot or two underground. This pipe is connected to the sprinkler heads. Sprinkler heads pop-up when activated on a lawn. Permanently raised heads are often used in gardens.
Professional installation of sprinkler systems can take anywhere from a couple of days to a week.
Sprinkler System Maintenance
Routine maintenance on an automatic sprinkler system includes replacing the timer ($100), valves ($25 apiece), valve boxes ($20), rotor heads ($25) and spray heads ($10). To replace most of these components, with labor, could cost $750-$1000. New pipes cost more. Doing it yourself would lower the cost.
