When designing a backyard, it’s helpful to plan the sprinkler system. A general rule of thumb is that each zone should be two feet deep and line up with the nearest irrigation pipe or drip irrigation system. The depth of a sprinkler head is typically one foot, but this varies by manufacturer so make sure you’re not too close!

Having a sprinkler system in your yard may be a simple and effective method to keep your plants well-watered. Above-ground sprinkler systems are available, but they may be a hassle to deal with, especially when it comes time to mow the grass.
The first step is to plan out the arrangement of your irrigation system. You may begin the installation process if you are satisfied that the plan will operate correctly. This is where you will dig your trenches and lay the pipe afterwards.
However, it is critical to dig the trench to the correct depth. It’s conceivable that certain normal lawn care may pierce your sprinkler lines if the trenches aren’t dug to the required depth.
This will need digging up your pipes, replacing them, and then digging deeper holes.
Some Depth Requirements Before Digging
Without any planning, no matter how wonderful the plans are, they may go wrong in a flash. Before you begin excavating, contact your local utility providers to have them come out and designate any buried lines, such as water and gas lines.
It’s also a good idea to contact the department of building regulations in your town. This might be for the city where you reside or the whole county.
When it comes to installing irrigation pipes, each location has various needs that will decide how deep they must go.
In general, most places will need you to bury your pipes between 8 and 12 inches into the soil’s surface. Because this measurement begins at the top of the pipe and ends at the soil’s surface, the trenches must be somewhat deeper.
So, if you wish to bury a two-inch-diameter pipe 10 inches under the earth, the trench you dig must be 12 inches deep.
There are two reasons why you want to bury them so deeply. The first is to safeguard against possible lawn-care equipment damage. Mowers and trimmers aren’t a problem; it’s the aeration equipment that you need to be concerned about.
The true reason sprinkler pipes are buried at that level is to keep them from freezing. This isn’t a concern if you live in a warm environment, but in colder climates, that depth can give enough freezing protection.
When cold fronts pass through, the cold doesn’t penetrate very far, safeguarding your sprinkler lines.
Your Trenches Are Being Dug
There are a few things to think about before you start digging. You could do it all by hand with a shovel, but it would take a long time and a lot of energy.
While budgets are necessary and comprehensible, it may be worth saving time and effort by using an alternative method.
If you have to dig, you may make it easier on yourself by watering the area for an hour at least two days before you want to dig. This allows the water to seep into the soil, softening it and making shoveling easier.
Instead of attempting to handle everything by hand, you should definitely hire a trencher for the bigger yards. A trencher may save you a lot of time and reduce your physical stress.
Best of all, they may be hired for a reasonable price from a local garden or home improvement shop.
Digging to the right depth is critical, regardless of whatever approach you use. If you do anything less, you risk damaging them during lawn maintenance or allowing them to freeze during the colder months of the year.
The easiest approach to get water for your sprinkler system is to connect it to an existing faucet on your water line. You may tap into the service line of your main water line if you want to do it the conventional, professional manner.
It will be necessary to install an anti-siphon valve in any case. The purpose of the valve is to keep lawn pesticides, brackish water, and fertilizers out of your main water supply.
Begin excavating the trench by digging it 8 to 10 inches deep and sloping the sides down at a 45-degree angle. To make the procedure of filling in the trench as simple as possible, keep your sod on one side and any dirt on the other while digging.
The final couple of inches of the trench will need to cover the valve manifold box, so you won’t be able to excavate the complete depth with your trencher. Place it in the ground, making sure the hole is just slightly bigger than the manifest.
When you’ve finished burying the manifold box, take one end and connect it to the main water line, fastening the clamps to keep it in place. After that, you’ll need to connect your PVC pipe to the valve manifold’s open section.
Continue installing piping down the open trench, using T connections for any pipes that link to the main line directly. Risers should be attached at certain positions, with 90-degree connections at each junction.
Also, make sure you use a thin coating of adhesive and apply it evenly while gluing these portions.
You may now begin putting the sprinkler heads once the sprinkler lines have been installed. Make sure you choose ones that complement your environment as well as your lawn’s watering requirements.
It’s not just plug and play; if you don’t do your research, you can make the incorrect decision.
Before you install the sprinkler heads, you’ll need to properly cleanse the system with water to remove any debris. Install your sprinkler heads into each of your irrigation system’s risers after you’re confident that the line is clean and clear.
Make sure the sprinkler heads are level with the soil level before filling up the trenches with sod and dirt heaps.
Install the controller last. This regulates the frequency and duration of waterings carried out by your irrigation system. Simply follow the manufacturer’s instructions when attaching the wires, and then test the system by connecting to the main water line.
When you’re certain that everything is in its appropriate location, you may adjust your sprinkler heads to ensure that your whole yard is adequately covered.
Is It Possible to Plant Over Sprinkler Lines?
Because of the sprinkler lines’ 12″ depth, the issue arises whether or not you can plant anything over them. It’s a good idea to keep everything you plant at least 15 feet away from your pipes in general.
If you choose something with a deep root system, they may be a little closer. They’ll usually skip the irrigation in favor of deeper, more luxuriant soil. The issue might be caused by trees and plants with shallow root systems.
Sprinkler lines may get entangled with shallow root trees, limiting or even puncturing them. You’ll have to dig up the sprinkler lines to repair or replace them if they’re broken. This entails a significant amount of time (and money) spent resolving an issue that might have been avoided.
Plant anything at least 15 feet away if at all possible for peace of mind. If your location doesn’t allow for that, choose plants with a deeper root structure to prevent harming your sprinkler lines.
What is the maximum number of sprinkler heads that may be used per valve or zone?
Per zone or valve, your irrigation system will only be able to handle a particular number of sprinkler heads. If you overload the valve, it may lower the pressure of all the linked sprinkler heads in the vicinity, or possibly stop them from operating altogether.
You must first determine your flow rate and water pressure before determining how many sprinkler heads you may utilize per zone. It’s also a good idea to select sprinkler heads that are of the same size.
Each head has its own water pressure and, as a result, uses water at a distinct pace. You’ll need to know the differences between sprinkler heads if you have a lot of them.
You’ll need a pressure gauge to check your water pressure. Install it in the nearest faucet to your water meter and make sure there is no water flowing anywhere, both inside and out.
Turn on the faucet with the gauge connected after you’re sure no other locations are utilizing water.
The gauge is intended to show you how much pressure is in the water. The unit of measurement is pound per square inch (PSI). You may also phone your local water company if you don’t have a pressure gauge or don’t want to go out and get one. They should be able to tell you how much pressure there is in the water.
You’ll need a measured container to determine your home’s flow capacity. If you happen to have a five-gallon bucket lying around, you may use it. Turn off every other faucet on your property, just as you would with the water pressure.
Turn on the faucet where your bucket is completely full, and time how long it takes to fill the container.
So, if it takes 300 seconds to fill a five-gallon container, divide 300 by five to arrive at the conclusion that a gallon container takes 60 seconds to fill. That is your water flow capacity.
Every zone in your irrigation system should contain between four and six sprinkler heads, according to a reasonable rule of thumb. If you have more than that, your water pressure in that zone will drop, lowering the water pressure in each of the sprinkler heads.
Troubleshooting Low Water Pressure
If you have the correct number of heads per zone but still have low pressure, the first step is to turn off the water at the source and examine the problem. The initial point of inquiry will be the heads.
Begin by digging around and unscrewing the sprinkler head in question from the riser. Remove the lid from the canister to remove the head, then rinse away any dirt or soil that may be blocking it up.
Remove the screen basket as well, and ensure sure it is properly cleaned. Finally, before reinstalling the head, adjust the watering range.
If the head isn’t the issue, the valve might be the culprit. Check your sprinkler system’s backflow device; it’s possible that it’s been closed and merely has to be opened.
Even if the sprinkler head and valve are in good operating condition, there’s a possibility you have a leak that’s draining your irrigation system’s water pressure.
Start by turning on the water and checking for any obvious leaks. Smaller leaks may be harder to detect at first, but after you locate the source of the leaking water, you may proceed. Cut off the water supply like you would while working on the irrigation system.
Remove the section of your sprinkler line that is damaged. Put a clamp on one end of the line, place a slip coupling over top, and tighten the clamp with the water off and the line open.
Rep the process on the opposite side, slipping your new PVC pipe in between the connections. After you’ve secured both, you should have a perfectly working new piece of pipe that will last a long time.
The “how deep do sprinkler lines need to be” is a question that has been asked many times. The answer is that the depth of the sprinkler line depends on how much water pressure it will be used with.
