Plumber Tools & Equipment Handling Flashcards

When cutting cast iron pipe with a snap cutter (soil pipe cutter), the chain should be:

Answer: Tightly wrapped perpendicular to the pipe centerline

The chain must be perpendicular and snug so all cutting wheels score evenly around the circumference, producing a clean snap.

Which measuring tool is most accurate for verifying that a drain slope meets the standard ¼-inch-per-foot fall?

Answer: Torpedo level with slope vial

A torpedo level with a graduated slope vial allows the plumber to confirm a specific percent or inch-per-foot grade directly.

A press tool (e.g., ProPress) creates watertight connections on copper or stainless tubing by:

Answer: Mechanically compressing a fitting with an o-ring using hydraulic jaw force

Press tools use a powered jaw to compress a special fitting around the pipe, deforming it against an internal o-ring to create a seal without heat.

What is the proper way to store a pipe wrench when not in use?

Answer: Lay it flat with the jaw closed to relieve spring tension

Storing a pipe wrench with the jaw closed relieves tension on the spring and prevents the adjustment nut from loosening over time.

What PPE is required when operating a power drain-cleaning machine (sectional machine)?

Answer: Safety glasses and rubber gloves

Safety glasses protect against splatter and rubber gloves protect hands from contaminated water and rotating cable.

A reciprocating saw (Sawzall) used in plumbing is best suited for:

Answer: Demolition cuts through pipe, framing, or mixed materials

The reciprocating saw's aggressive blade stroke makes it ideal for rough demolition cuts through pipes, nails, and wood simultaneously.

When a pipe vise is mounted to a tripod for field work, the pipe should be secured:

Answer: Firmly in the vise with the work end extending toward the plumber

Securing the pipe with the work end toward the plumber allows stable access for threading, cutting, or reaming operations.
