Wet pipe sprinkler
Automatic Sprinkler of Connecticut LLC specializes in the simplest and most cost-effective types of automatic fire sprinkler systems, wet pipe sprinklers. Wet pipe sprinklers are the most common type of sprinkler system and are very reliable. They use water from a pressurized supply line to activate the sprinklers in case of smoke or heat detection, quickly suppressing any fires while minimizing damage.

An automatic sprinkler system is a system in which sprinkler heads are fixed in piping system were pipe is fully filled with water or air under pressure and, at a certain calibrated temperature, sensing elements in sprinkler head breaks and allows water flow. Other types of systems rely upon electrical sensors (smoke and heat sensors, or manual switches) to initiate the flow or to pressurize the pipe so that sprinkler heads activated by the heat will flow water. Somewhat more rare systems, for extremely high hazards such as rubber tire storage in a warehouse, may have sprinkler heads that are always "open", allowing the entire room to be flooded when the pipe is pressurized.
If the pipe is metal try a metal detector. If plastic, get out your shovel.

Pipe schedule systems were used until hydraulic calculations became the norm in the mid 80's. You can tell if the system is pipe scheduled when the piping sizes decreases as you get farther away from the water source (sprinkler riser). The larger mains will reduce as less branch lines and sprinkjlers are being supplied.
You will not have any pressure after the first few sprinkler heads.
This system is used in a non heated space. Parking garages, warehouses, carports and so on. The system has pressurized air in the pipeing from the sprinlker head to the water source. Water does not enter the system untell a sprinkler head is set off.
There are two main methods of sprinkler system installation: open trench and pulled pipe. Open trench typically uses PVC pipe and pulled pipe typically uses poly pipe. Other than the pipe and fittings, the main difference in installation will be that the pulled pipe system requires a hole and saddle tee at the location of each sprinkler head. The steps for installing an automatic sprinkler system using an open trench method are: 1. Start with a good sprinkler system design (try searching "sprinkler system designer" for support options) 2. Make sure that you have all necessary tools, equipment, and permits 3. Have Blue Stakes mark all utilities prior to any digging 4. Install a backflow prevention device according to code 5. Place flags at the location of each sprinkler head 6. Mark and dig all trenches and valve manifold locations 7. Build and install valve manifolds (preassembled valve manifolds can make this easier) 8. Connect mainline pipe from water source connection to valve manifolds 9. Lay lateral line pipe from the valve manifolds to the location of each sprinkler head 10. Install tees and swing assemblies for each sprinkler head and flush lines 11. Connect sprinkler heads to swing assemblies; set head to level with ground 12. Install sprinkler timer/controller and connect sprinkler wire from timer to valve manifolds 13. Install nozzles on sprinkler heads 14. Install valve boxes (as required) and backfill all trenches 15. Run a zone by zone test and adjust nozzle patterns
