Proper preparation of the pipe for gluing includes cutting the pipe fairly straight and using a utility knife or emery cloth to remove any burrs left over from the cutting process. These burrs cause trails in the glue, weakening the joint and increasing the chance of leaks. To eliminate burrs and ensure straighter cuts, use a tubing cutter for pipes under 2 inches in diameter.

Before applying glue to the joint or pipe, Hometime.com recommends dry-fitting the pipe and ensuring that drain lines have the proper drop for drain flow. The Family Handyman recommends using the glue to seal the cut ends of ABS pipe before gluing. This pipe has a cellular or foam core construction, which allows air to pass through unless the cut ends are sealed, causing the system to fail any required pressure tests.
