Use a shovel to gently scrape the dirt from the area to find each buried head. Use a metal detector to find buried sprinkler heads. Many valves have metal parts you can locate by running the metal detector over the surface of the ground. Valves are located directly under sprinkler heads.
How do I find a sprinkler head without water?
Pull a metal garden rake gently over the area of the grass where you suspect sprinkler heads are located if you cannot turn water on to the system. If the sprinkler heads are buried, you may need to apply greater pressure to the rake so it digs slightly into the soil.
Can a metal detector find sprinkler valves?
A metal detector is unlikely to work because the valves are most likely to be plastic with very little metal in them. If you don’t have any luck probing small low spots near the begining of the zone, it may require someone to do a wire trace for the valve.
How do I find my sprinkler lines?
You can tell (roughly) where the pipes will be for that zone by finding the shortest path from the valve box that connects all the sprinklers in a zone. As long as you dig carefully, you shouldn’t have too much trouble. The pipes are usually pretty tough and are usually buried about a foot or so under the ground.
How deep are sprinkler heads buried?
The trenches will be relatively shallow, usually 6 to 12 inches deep, depending on your area’s freeze cycles and frost severity. The trench must also be deep enough to allow the sprinklers to retract underground to prevent breakage from lawn machines. Dig the trench by hand or rent a trencher (a real timesaver).
How do I find buried sprinkler valves?
The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.
How far apart are sprinkler heads?
Types of Sprinkler Heads Because of the lower PSI the distance of the spray rarely exceeds 15ft. Meaning that spray heads should never be placed further than 15 ft. apart as this would create dry spots (i.e. dead grass) in your lawn.
How much does it cost to find sprinkler valves?
Sprinkler System Repair Cost by Type of Replacement Type of Replacement Average Replacement Costs (Parts and Labor) Valve Box $75 – $125 Filter $75 – $150 Solenoid $85 – $150 Valve $85 – $150.
Where is the main sprinkler system valve usually installed?
In newer lawn irrigation systems, the valves should be installed in valve boxes. These can often be seen easily. There is a single valve box located near where the irrigation pipes enter the ground in small yards.
How much do sprinkler valves cost?
It’s a fairly easy job to locate and replace broken sprinkler heads, and even to reset a controller, but it’s much more difficult to locate broken or leaking pipes and valves. You’ll probably need to call an irrigation service specialist to do that for you for an average cost of $75–$250.
How can I find my sprinkler lines without digging?
If you prefer to locate the lines and heads of your system without digging, rent a valve locator or even a metal detector and mark areas once found – better yet, call call 811, a federally mandated service, and ask someone to come out and locate the system for you.
How is sprinkler height measured?
The size of a sprinkler is determined by the height of the stem – the part that pops up.
Should sprinkler heads level with ground?
The correct height for a sprinkler head is to have the top of sprinkler head just above the soil surface. No more than a quarter of an inch above the ground level. This lowers the tripping hazard, and a lawn mower can go past it without causing any damage.
How high should sprinkler heads be before sod?
The sprinkler heads should extend about 5/8-inch above the ground before sod is laid and should be level with the sod root base afterward.
How many zones can a sprinkler valve control?
Can I run more than one zone at a time? For the controllers HC, PROHC, HPC, you can only run a single zone at a time based on the power output available. Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties.
How do you trace an irrigation wire?
In automatic irrigation systems, a third way to find lost valves is to follow the wires from the controller. The wires run alongside the PVC pipe to the irrigation valve location. Dig small holes every ten feet to trace the wire. Be careful not to cut the wire.
How close can sprinkler heads be to each other?
Current fire safety codes require sprinkler heads always to be a minimum of 6 feet apart from one another to avoid cold soldering.
How many sprinkler heads can you have on one line?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
How long do sprinkler valves last?
One of the components that you may need to replace regularly are the wires, often due to improper installation and corrosion. Valves will give you 10 to 15 years of service, while controllers 5 to 10 years.
How much is a fire sprinkler head?
In general, here are the costs you can expect: $1 to $2 per sprinklered square foot for new construction projects. $2 to $7 per sprinklered square foot for retrofitting existing homes and businesses. $2 to $4 per sprinklered square foot for retrofitting high-rise buildings.
