Introduction

Drain extensions solve alignment issues when fixture outlets sit above or beside the main waste line. They maintain proper and watertight seals without major pipe alterations.

  • Measure tailpiece diameter and length needed before ordering to ensure compatibility.
  • Choose extensions made from Schedule 40 PVC or brass for corrosion resistance in humid environments.
  • Look for included gaskets and slip nuts to complete the connection without extra purchases.

Verify local plumbing codes and select the appropriate diameter and material for your installation.

FAQs

Common diameters are 1-1/4 inch and 1-1/2 inch; lengths range from 6 to 24 inches.

Yes, most PVC extensions can be trimmed with a fine-tooth saw; deburr edges before assembly.

Check outlet height; some disposals require specific tailpiece lengths or adapters.

Threaded connections benefit from PTFE tape; slip-joint connections rely on compression gaskets.

Ensure the gasket seats evenly and hand-tighten plus a quarter turn with a wrench; avoid over-tightening.
