Project step-by-step (7)

Step 1

Make Square Cuts for Strong PVC Joints

  • Make an improvised guide by screwing together scraps of 2x4.
  • Saw using a handsaw with a blade that's 3 or 4 inches wide.
    • Note: Square pipe ends fit snugly into the fittings, allowing plenty of contact area for the solvent cement to work. They also make a smoother interior surface for better water flow. 
    • Pro tip: Special saws for cutting plastic pipe are a worthwhile investment if you do much plumbing work. You'll find them in the plumbing tool area or with the handsaws in most home centers and hardware stores. Otherwise, any fine tooth saw will work.

Step 2

De-Burr the Inside

  • Roll a quarter sheet of 80-grit sandpaper into a tube and flatten it slightly to match the curve of the pipe.
  • File off the inner burrs with the sandpaper.
  • Hold the sandpaper at an angle and sand the inside and outside (see below) of the plastic pipe until you create slightly beveled edges.
    • Note: Left in place, burrs can snag hair and other debris, causing clogs.
    • Pro tip: You can remove burrs with a file or pocketknife, but sandpaper is easier to use and works great.
