Standard Pipe Connections

This guide explains how to properly connect drainage pipes using common fittings such as wyes, elbows, and waterproof tape.

Why This Matters

Proper pipe connections are crucial for system integrity and preventing leaks. These techniques ensure durable, waterproof joints that will last for years.

1. Pipe-to-Pipe Connections

1

Verify Layout

Proper planning prevents costly mistakes and ensures a professional installation.

  • Measure twice, cut once
  • Confirm the full layout of your pipe run
2

Cut the Pipe

Clean, precise cuts are essential for proper fitting and sealing.

  • Use a fine-tooth sawzall blade or a utility knife with a metal blade
  • Make clean, square cuts to ensure a tight seal
3

Dry Fit Components

Always test fit before applying permanent connections to avoid alignment issues.

  • Use a pipe coupler to assemble the connection without tape first
  • Confirm the alignment with intended slope and direction
4

Apply Waterproof Tape

Proper taping technique creates a watertight seal that prevents system failure.

  • Use 4" waterproof pipe tape
  • Start with one full wrap on the first pipe
  • Spiral evenly across the seam, ending with a full wrap on the second pipe
  • Apply a total of at least 8 wraps
  • Final taped section should be at least 8" long

2. Wye and Elbow Connections

1

Pre-Measure and Cut

Accurate measurements prevent forced connections that can damage fittings.

  • Identify the exact location and angle for wyes or elbows
  • Cut pipe to fit these without forcing or bending the fittings

2

Dry Fit and Confirm Orientation

Proper orientation ensures optimal water flow and prevents system bottlenecks.

  • Dry fit fittings before applying tape
  • Orientation is critical, especially for multi-pipe merges
  • Double-check angle and flow direction
