Nailing PEX into the ground outside may seem like a daunting task, but it’s actually quite simple with the right tools and techniques. PEX, or cross-linked polyethylene, is a type of flexible plastic tubing that is commonly used for plumbing applications. It is resistant to corrosion and freezing, making it an ideal choice for outdoor use. However, PEX is not as strong as metal pipe, so it is important to take care when nailing it into the ground.
In this article, we’ll show you how to nail PEX into the ground outside. We’ll cover everything from choosing the right tools to preparing the ground and nailing the PEX. By following our tips, you can ensure a secure and leak-free installation.
First, you’ll need to gather your tools. You’ll need a hammer, a nail set, and a pair of pliers. You’ll also need some PEX tubing and some nails. The type of nails you need will depend on the type of soil you have. If you have hard soil, you’ll need to use galvanized nails. If you have soft soil, you can use regular nails.
Preparing the Ground for Excavation
Before starting any excavation work, it’s crucial to prepare the ground adequately to ensure safety and efficiency during the process.
Locating Underground Utilities
Before digging, it’s imperative to locate any buried utilities in the excavation area, such as electrical cables, gas pipelines, and water lines. Contact your local utility companies for assistance in marking these utilities and obtaining any necessary permits.
Establishing Excavation Boundaries
Clearly define the boundaries of the excavation site using stakes or spray paint. This will help prevent accidental damage to surrounding structures or vegetation. Ensure that the boundaries are marked accurately and are visible to everyone working in the area.
Clearing the Surface
Remove any vegetation, debris, or obstacles from the excavation site. Clear away any trees, shrubs, rocks, or other obstructions that may hinder the excavation process. Use appropriate tools and equipment for efficient clearing.
Grading and Leveling the Ground
If necessary, grade and level the ground to facilitate excavation. This may involve removing excess soil or filling in depressions to create a stable and even surface. Use a level to ensure the ground is flat and level.
Protecting Surrounding Areas
Take measures to protect surrounding structures, vegetation, and surfaces from potential damage during excavation. Install protective barriers, such as fences or tarps, if necessary. Secure loose soil or debris to prevent erosion or runoff.
Excavating and Leveling the Trench
1. Determine the Trench Location and Dimensions:
Mark the location of the trench along the intended plumbing route. Determine the depth and width requirements based on the PEX piping size and local building codes.
2. Excavate the Trench:
Use a shovel or trenching tool to excavate the trench. Dig straight down to the required depth, ensuring a level bottom surface. Sloping the trench walls may be necessary for drainage if the soil is prone to water accumulation.
3. Level and Compact the Trench Floor:
This step is crucial for ensuring proper PEX pipe support and preventing settling. Follow these detailed steps:
- Use a level to check the trench floor for any unevenness. Fill in any depressions with tamped gravel or sand.
- Compact the trench floor by tamping it firmly with a hand tamper or a plate compactor if available. This will create a stable and level base for the PEX piping.
- Create a uniform base for the PEX pipe by pouring a layer of leveling gravel or sand onto the compacted floor. This will provide a smooth surface and prevent the pipe from being distorted during installation.
Measuring and Cutting the PEX Pipe
To ensure a proper fit and prevent leaks, it’s crucial to measure and cut the PEX pipe accurately. Follow these steps:
1. **Determine the Length:** Measure the distance between the two points where the PEX pipe will be connected. Add a few inches (5-10 cm) to allow for a secure connection and any necessary fittings.
2. **Mark the Pipe:** Using a tape measure and a permanent marker, mark the desired length on the PEX pipe.
3. **Use a PEX Cutter:** Specialized PEX cutters are designed to cut the pipe cleanly and perpendicular to its length. Place the pipe into the cutting tool and follow the manufacturer’s instructions for a precise cut.
4. **Deburr the Cut Edges:** After cutting, the edges of the pipe may have small, sharp burrs that can hinder proper sealing. Use a deburring tool or a fine sandpaper to smooth out the edges, removing any rough areas or plastic shavings. This ensures a tight seal and prevents potential leaks.
| Length (Inches) | Recommended Fittings |
|---|---|
| < 20 | Barbed fittings |
| 20-50 | Crimp rings and crimp tool |
| > 50 | Expansion fittings |
How to Nail PEX into Ground Outside
PEX (polyethylene cross-linked) is a durable and flexible plastic tubing used in plumbing applications. If you need to install PEX tubing underground, you’ll need to nail it into the ground for stability. Here’s how to do it:
- Mark the location where you want to install the PEX tubing.
- Dig a trench that is deep enough to accommodate the PEX tubing and about 6 inches wider than the diameter of the tubing.
- Place the PEX tubing in the trench.
- Drive nails through the PEX tubing into the ground. Space the nails about 2 feet apart.
- Backfill the trench with soil and tamp it down firmly.
Once you’ve nailed the PEX into the ground, it will be securely in place. You can then connect it to your plumbing system and start using it.
