When we install your irrigation system; we determine how many stations your system will need based on the size of the yard, the type of grass and plants you’re irrigating. We then determine the amount of water pressure the valve is able to produce. Once the dimensions and water pressure is assessed, the installation can begin. We dig trenches in straight lines a minimum of 12″ below grade and install PCV piping which connects to valves and the double check. Each station can hold up to ten irrigation heads and needs a control valve which is installed in the same vicinity of that station. Normally a lot has one double check (or main valve). That double check can hold up to ten stations. Each station is set on a timer to turn on and off at your discretion (and no two stations can be active at the same time). Rain sensors may be added to disengage your system during storms.
