PERT (Polyethylene of Raised Temperature Resistance) pipe has become a popular choice for plumbing applications due to its flexibility, durability, and resistance to corrosion. But what about digging deep? Can you bury the PERT pipe underground? The answer, like most things in plumbing, requires a bit of nuance. The Short Answer: Yes, you can bury PERT pipe under certain conditions and with proper precautions. The Long Answer: Before grabbing your shovel, consider these factors:

Local Plumbing Codes:

The first (and most important) step is to check your local plumbing codes and regulations. Some areas may have restrictions or specific requirements for burying PERT pipe. These may depend on:
  • Application: Is it for potable water, irrigation, or other purposes?
  • Pressure rating: What pressure will the pipe be subjected to?
  • Soil conditions: Are there potential hazards like rocks or heavy clay?
  • Frost line: In colder climates, the pipe must be buried deeper than the frost line to prevent freezing.

PERT Pipe Specifications:

Not all PERT is created equal. Ensure your pipe meets the necessary standards for underground use. Look for NSF 61 certification for potable water applications and ratings for pressure and temperature resistance.

Installation Best Practices:

Here are some key tips for a successful underground PERT installation:
  • Use proper bedding: Surround the pipe with a layer of sand or gravel to prevent stress and movement.
  • Protect against punctures: Consider using warning tape or conduit to alert future excavators.
  • Provide adequate drainage: Ensure water doesn't collect around the pipe to prevent corrosion.
  • Use correct fittings: Opt for fittings specifically designed for underground PERT connections.
  • Hire a qualified plumber: For critical applications or complex installations, consult a professional with experience in burying PERT pipe.

Advantages of Burying PERT Pipe:

  • Protection from the elements: Underground pipes are shielded from damage caused by weather, traffic, and pests.
  • Enhanced aesthetics: Pipes are hidden from view, keeping your landscaping pristine.
  • Improved freeze resistance: In cold climates, burying below the frost line prevents freezing and potential burst pipes.

Alternatives to Burying:

  • Above-ground installation: In some cases, it may be easier and more cost-effective to run the pipe above ground, using supports and protective measures.
  • Alternative pipe materials: Depending on the application, other materials like PEX or CPVC may be better suited for above-ground installations.
In Conclusion: Burying PERT pipe can be a safe and effective solution for various plumbing needs, but it's crucial to follow local regulations, use the right type of pipe, and adhere to proper installation practices. Remember, when in doubt, consult a qualified plumber for guidance. Bonus Tip: For a comprehensive resource on burying PERT pipe, check out the manufacturer's specifications and installation guidelines. They'll provide specific details and recommendations for your project.
