High water pressure could be the reason for pipes to rattle when you turn on the outside sprinklers. You may need to have a reducer valve installed.
Singing water pipes can be caused by air that is trapped in the pipes. The air can cause a whistling or singing sound, or it can cause the pipes to knock or rattle.
Irrigation sprinklers
Rain, drain pipes, hoses, sprinklers, ect.
Pipes rattle when water is turned off due to a phenomenon called water hammer. This happens when the sudden stop of water flow creates a pressure surge that causes the pipes to vibrate and make noise.
The sprinklers may not be working properly due to issues such as clogged nozzles, damaged pipes, insufficient water pressure, or a malfunctioning control system. It is important to inspect and address these potential problems to ensure the sprinklers function effectively.
Water Hammer.
Most likely.
Water hammering on any quick closing valves
When the steam hits colder piping it turns to condensate and the steam hitting the water (condensate) produces hydraulic shock waves.
Sprinklers in a fire protection system are connected to a network of pipes filled with water. When a fire is detected, the heat activates the sprinkler heads, releasing water to extinguish the flames.
This is called water hammer. It is caused by rattling pipes or by the jumpers inside the tap which rattle.
Sometimes it's caused by air in the pipes.
