Quck answer
Locating underground plastic pipes is essential for various reasons, such as preventing damage during construction or repairs. Here are some methods to help you locate these pipes:
1. Use a pipe locator: A pipe locator is a device that uses electromagnetic waves to detect the presence of plastic pipes underground. It can accurately locate the pipes’ position and depth.
2. Use ground-penetrating radar (GPR): GPR uses radar pulses to create an image of the subsurface. It can detect changes in the material composition, allowing you to locate plastic pipes.
3. Look for surface markers: Some plastic pipes have surface markers or signs indicating their presence underground. These markers can help you identify the approximate location of the pipes.
4. Consult utility plans: If the pipes are part of a utility system, you can obtain utility plans from the relevant authorities. These plans provide valuable information about the location of underground pipes.
Remember to exercise caution while locating underground pipes and consider hiring professionals if you are unsure or dealing with complex systems.
When planning to dig on your property, it is important to call 811 to locate public utilities such as water, electrical, sewage, and gas lines. However, if you are looking for privately installed pipes made of PVC or polybutylene, this free service will not be of much help. Finding plastic pipes can be challenging, but there are some DIY tricks you can try before hiring a professional.
Find the General Location and Probe
Most underground water pipes follow a straight line from the water source to the fixture that distributes water. Sprinkler lines run from the valve to the sprinkler heads, while a septic waste pipe runs from the house to the septic tank. If you know where these are, you have a general idea of where the pipes should be. Use a T-handle probing bar to gently push into the ground until you feel resistance, which is likely the pipe. Keep probing a few inches in both directions until you find the pipe.
Use a Metal Detector or PVC Pipe Locator
If the plastic pipe does not contain electrical wires or tracer wire, a metal detector cannot locate it. However, if one end of the pipe is open, you may be able to feed tracer wire into it and use a metal detector to find the buried part. Alternatively, you can use a PVC pipe locator that uses an acoustic signal or ground-penetrating radar to locate the pipe. These are not easy to use and renting one is generally not an option. It’s best to hire a pro if the pipe is buried too deep for a probe to find.
Using Tracer Wire to Locate Buried Plastic Pipes
Locating buried PVC and poly pipes can be a difficult task, but including tracer wire in every trench where you bury these types of pipes can make it easier. With the wire in place, you can use a metal detector to locate the pipes from above ground, saving time and money on hiring a professional to locate them.
Tracer wire is an affordable solution, costing less than $25 for a 100-foot roll. Simply lay it on top or to the side of the pipe before backfilling the trench. For deep pipes, consider backfilling with a few inches of material before laying the wire to keep it closer to the surface and within range of a standard metal detector.
FAQ
1. What are the common methods used to locate underground plastic pipes?
The common methods used to locate underground plastic pipes include the use of ground penetrating radar (GPR), electromagnetic induction, and acoustic detection. GPR uses radar pulses to create images of the subsurface, allowing the user to identify the location and depth of plastic pipes. Electromagnetic induction works by inducing an electromagnetic field into the ground and detecting disruptions caused by the presence of plastic pipes. Acoustic detection involves using specialized equipment to listen for the sound of flowing water or air escaping from the pipes.
2. Are there any challenges when locating underground plastic pipes?
Locating underground plastic pipes can present some challenges. Plastic pipes do not conduct electricity, making it difficult to use traditional methods such as electrical conductivity to locate them. Additionally, plastic pipes may be buried at varying depths, making it important to use methods that can accurately determine the depth of the pipes. Finally, other underground utilities and structures can interfere with the detection process, requiring careful planning and interpretation of the results.
3. What precautions should be taken when locating underground plastic pipes?
When locating underground plastic pipes, it is important to take certain precautions to ensure accuracy and safety. Before beginning any detection work, it is crucial to contact the relevant utility companies to obtain information about the location of their underground infrastructure. This can help avoid accidental damage to other utilities and structures. Additionally, it is important to use proper safety equipment, such as gloves and safety goggles, when conducting detection work. Careful interpretation of the detection results is also necessary to ensure accurate identification of the pipes and prevent unnecessary digging or excavation.
