How To Find The Underground Sprinkler Wires Without Digging?

Posted on: June 24,2022

Most homeowners nowadays have an underground sprinkler system to keep their lawns green and beautiful all year long. One of the biggest advantages of an underground sprinkler system is that you don’t have to mow your lawn on regular basis, since the sprinklers will do it for you without even touching your lawn. 

Without digging, it is possible to find sprinkler lines by getting a design map from the company that installed the system. If this is not possible, one could go to the valve box and follow a line back to each of the head sprinklers in a circuit. Or one could utilize an electronic water-detection device. You can also use Noyafa NF-816L to find the underground sprinkler wires without digging and it’s the easiest way.

The only problem that may occur here is when you decide to make some changes or repairs in your sprinkler system and you need to find out where are the underground sprinkler wires located. This can be done without digging and damaging the grass by using a utility locator.

Utilizing a Design Map to Find Sprinkler Lines without Digging

One of the best ways to find your sprinkler lines without digging is by using a design map that was originally created when you installed your irrigation system. These maps will typically show where all of your valves and manifolds are located. 

You might also want to check with local building codes before digging; some places will require permits and could levy fines if you start digging without them. While it may seem like a lot of work, it’s always better to be safe than sorry. 

It’s not uncommon for homeowners to end up spending thousands of dollars on landscaping repairs after accidentally digging into sprinklers or power lines. Even if you think you know exactly where everything is, take a few minutes to do a little research first. It could save you from having to dig another hole later down the road.

Physically Locate Your Sprinkler Lines Without A Design Map

If you can't find a design map for your sprinkler system, an alternative is to locate the actual sprinkler lines. One needs to know what a typical sprinkler line looks like in order to spot them easily.

Know Your Sprinkler System Components

The first component of your irrigation system is the control box. It does just what its name says- it regulates when your system turns on and off. When activated, a solenoid connected to a valve allows for water flow from wherever you get your water from (a nearby well or reservoir). 

The next stop was the valve box which housed both the solenoid and the valve. From here, pipes carried water to different sprinkler heads located all around the lawn.

Steps To Find Hidden Sprinkler Lines

In the event that you continue legitimately, you shouldn't have an issue finding your sprinkler lines:

  • Find the control box. The crate will for the most part be in your carport or storm cellar. Follow the electrical stockpile to where the wires exit.

  • Head outside and see where the electrical stock goes into the ground.

  • The underground valve box ought to be close by. The valve box might be covered with soil, so spotless and open on the top.

  • Assuming that you have more than one circuit, each will have its valve box.

  • Observe the active water pipe heading from the valve box.

  • Switch on the sprinkler framework. The control box ought to have a manual supersede. See which sprinkler head(s) spring up first.

  • If you want to repair a broken sprinkler system, start by cutting off water flow before beginning work.

Points to Keep in Mind when Locating your Sprinkler Lines

When you have a well and sprinklers, it can be confusing to figure out which system is which when you are working on one part of your lawn. A great way to locate your underground sprinkler lines without having to dig up your yard is by using an electrical wire locator tool. 

These tools work great because they locate metal objects underground by transmitting high-frequency pulses into them and then listening for the sound that bounces back. Because underground water lines are made of metal, they will easily register with these types of tools; even aluminum in standard household wiring registers with a loop detector like the ones used by electricians. 

This makes them ideal for locating underground sprinkler systems as well. In addition to being able to find your main line, you can also use them to find leaks or broken wires where no water is coming through at all. These probes make it possible to search for buried pipes and wires without needing to dig random holes all over your property.

Noyafa NF-816L: Easiest Way To Locate Sprinkler Lines Without Digging

Noyafa NF-816L. It’s an advanced underground wire locator device. It will find any underground sprinkler system without ever digging up your yard or garden. Simply insert it into your water supply and plug it in! If there are any leaks it’ll sound an alarm and immediately notify you of its location using a range of flashing lights on top, helping you easily locate where to patch up your home's sprinklers. 

Also provides additional information such as how much water is being used by each zone, how many minutes each zone has been running etc. Highly recommended for anyone with a sprinkler system installed in their yard. Definitely worth investing in if you don't want to dig holes all over your property looking for those pesky sprinkler lines. This device does all of that work for you.

Often if you need to locate underground sprinkler lines before digging, you call in a professional. But there’s an easier way for homeowners to find sprinkler and irrigation lines. Noyafa NF-816L is a locator tool that allows homeowners to survey their lawn without having to dig into it or hire a pro. 

You just tap the locator tool on your lawn and listen for water leaks with its built-in speaker (or take an audio recording of your garden’s sounds with its included microphone). When you hear running water, you can mark that spot and dig up your lawn later—saving time, money, and headaches down the road. 

Mark Out Your Sprinkler Lines And Heads

These days, many sprinkler systems are buried directly in your lawn. They’re often marked by a set of PVC lines—or even metal pipes and valves. Either way, it’s pretty easy to trace them back to where they hook up with your home’s main water supply. 

If you have an older sprinkler system installed above ground, you should be able to find where it leads (often in your garage or basement) without digging at all. Just remember that whatever markings are on your system will tell you exactly how many heads (and thus how much water) it can support. 

For example, if there are four lines leading from a single outdoor spigot—don’t hook up more than two zones. It might work for a while, but over time you could damage your entire sprinkler system. Also, some codes require a certain distance between each head (six feet is common). Be sure to check local codes before drilling any holes.

Electronic Water Detection To Find Sprinkler Lines

The quickest and most effective way to find out the location of your sprinkler lines is by hiring a device called an electronic radio detection machine with a microphone. This handheld device will easily identify where the water source is coming from, even when it's outside in plastic tubing. All you need to do then is hire someone who specializes in this task if you want to keep things simple; or if you're feeling ambitious, come up with some contraptions of your own.


The easiest way to find your sprinkler lines is by using Noyafa NF-816L. And another good way is the design plan given by the company that installed them. If you cannot obtain a design plan, then physically map them out or have a professional come and see if they can locate them with a special electronic machine. 

Keeping up-to-date about what width of space between different distance zones for each head is recommended will greatly increase your chances of success when finding your sprinkler lines; it'll also help make sure that your system stays well taken care of. But if none of these work - don't give up. Call a professional.
