PEX (cross-linked polyethylene) pipe is revolutionizing home plumbing systems with its flexibility, durability, and ease of installation. If you’re looking to upgrade your existing copper or galvanized steel pipes, PEX is an excellent choice. This comprehensive guide will provide step-by-step instructions on how to install PEX pipe in your house, empowering you to tackle this project with confidence.

Materials and Tools

Before embarking on your PEX pipe installation, gather the necessary materials and tools:

  • PEX pipes (type A, B, or C)
  • PEX fittings (elbows, tees, unions, etc.)
  • PEX crimp rings
  • PEX crimping tool
  • Pipe cutter or shears
  • Measuring tape
  • Pencil or marker
  • Safety glasses
  • Gloves

Step 1: Plan Your Pipe Layout

Thoroughly plan the new PEX pipe layout before starting the installation. Determine the location of fixtures, appliances, and any potential obstacles. Mark the pipe runs on walls and floors using a pencil or marker.

Step 2: Remove Old Pipes (Optional)

If replacing existing pipes, shut off the water supply and drain the system. Cut out the old pipes using a pipe cutter or hacksaw. Clean the surfaces where the new PEX pipes will be installed.

Step 3: Cut PEX Pipes to Length

Use a pipe cutter or shears to cut PEX pipes to the desired lengths. Ensure clean, perpendicular cuts for optimal fitting performance.

Step 4: Insert PEX Fittings

Push the PEX pipe into the desired PEX fitting until it reaches the stop. Use a pair of pliers to ensure a snug fit.

Step 5: Crimp PEX Fittings

Secure the PEX fittings using a PEX crimping tool and crimp rings. Position the crimp ring over the fitting and pipe connection, then use the crimping tool to apply even pressure around the ring.

Step 6: Install PEX Pipes

Route the PEX pipes along the planned layout and secure them to walls or studs using PEX clamps or straps. Maintain a slight slope for drainage.

Step 7: Connect to Fixtures and Appliances

Connect the PEX pipes to fixtures and appliances using PEX fittings and adapters. Ensure tight connections and use sealant where necessary.

Troubleshooting Common Issues

  • Leaking fittings: Check if the crimp rings are properly installed and tightened. Replace any damaged or loose rings.
  • Kinks or bends in pipes: PEX pipes should be installed without any sharp bends or kinks. Straighten or replace damaged sections.
  • Low water pressure: Ensure all connections are tight and that the water supply is fully open. Check for any obstructions in the PEX pipes.

The Benefits of PEX Pipe Installation

  • Flexibility: PEX pipes can be easily bent and routed around obstacles, reducing the need for multiple fittings.
  • Durability: PEX pipes are resistant to corrosion, freezing, and UV damage, ensuring a long lifespan.
  • Ease of installation: PEX pipes and fittings are easy to connect and require minimal tools.
