A properly operating water sprinkling system is essential if you want to have a properly maintained landscape around your home. A water sprinkler system is an exact science. If you over water, you have mushy ground with diseases, dying vegetation, shifting foundations, a high water bill and many other problems. If you under water, you have dry ground with diseases, dying vegetation, a not so high water bill, shifting foundations and many other problems. If you apply the right amount of water, you have flourishing vegetation, a predictable water bill, stable foundations, and minimal problems.
