Long pipes, fastened down too tightly, can cause some strange, very loud sounds with changes in temperature… Just for the record: most fire sprinkler systems are at the same pressure as your domestic plumbing.
Why is my sprinkler system making a loud noise?
Improper Water Pressure
High water pressure entering your irrigation system may produce loud sounds called water hammer, reveals Irrigation Tutorials. Because of their echoing effect, the noise may seem like it is emanating from a particular sprinkler.
What is the most common obstruction to sprinkler systems?
Calcium carbonate obstructions
Calcium carbonate obstructions are most common in sprinkler systems supplied from non-potable wells or surface water in places where water supplies are known to be hard. These blockages can’t be detected or corrected by normal flushing operations.
How do I get rid of air in my sprinkler system?
Remove the air you need to manually open two or more of the circuit valves at once. Run the water for a while in order to force all of the air out. Make sure to close the valves one at a time. A pressure surge can be caused if you close them at the same time and the surge could damage your irrigation system.
Is a sprinkler system pressurized?
The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi. You can measure the water pressure at your site with a flow meter or water gauge attached to an outdoor faucet.
How do you find a blockage in irrigation system?
If you know where the pipe runs through the landscape you can use a “fish tape” to find out where the blockage is. if the pipe has an open end you feed the tape in there. If not, yuo may need to cut a section of the pipe out to insert the tape. Just feed the tape into the pipe until it hits the blockage.
How are obstruction investigations conducted?
This more comprehensive obstruction “investigation” is conducted by internally examining the following four points in a system: system valve, riser, crossmain and, branchline and is only required when one of the 14 problems listed in Section 13.2. 2 is present.
What pressure should a fire sprinkler system be?
7 pounds-per-square-inch
➢ Fire sprinklers typically require only 7 pounds-per-square-inch (psi) to operate, which is less than the minimum required pressure for residential plumbing fixtures.
How do I test the water pressure in my sprinkler system?
Finding the Pressure or PSI
To find out what the pressure–or pounds per square inch of force (PSI)–of the water in your home, you’ll need to buy a pressure gauge. This gadget screws onto the outlet of your spigot and measures the static pressure, or the amount of pressure when no water is being used.
How do I check my sprinkler pressure?
Testing PSI at the Nozzle
Find the last sprinkler head on the zone you are testing. Attach your pitot tube to your pressure gauge or connect your gauge and adapter tee to the spray head. Turn on the zone and head over to the sprinkler you are measuring. Note: Be prepared to get wet!
Can a bad sprinkler valve cause low pressure?
Here are the common issues that lead to lowered water pressure: The valves located on your preventer device for backflow isn’t completely open. There is a break or leak in your sprinkler or water line. Your sprinkler heads have accumulated dirt or have clogged.
How do I know if my sprinkler valve is bad?

What causes low water pressure in a sprinkler system?
The most common cause of low water pressure in sprinklers is the backflow preventer valves not opening fully. There are two main pipes in your backflow preventer – one horizontal and one vertical. Each pipe has a handle that can be turned to run with the line or across to open the valve.
What will happen if a sprinkler system is working under low pressure?
Low water pressure in your sprinkler system cuts down the irrigation range and can even cause the sprinkler heads not to pop up at all. Here are some of the most common culprits: The valves on the backflow preventer device aren’t all the way open. The shut-off valve or main water valve isn’t all the way open.
