PC Plumber Tools & Equipment Handling 3

Question 1

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

Accepted Answer

Tightly wrapped perpendicular to the pipe centerline

Answer

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

Question 2

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

Accepted Answer

Torpedo level with slope vial

Answer

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

Question 3

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

Accepted Answer

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

Answer

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.

Question 4

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

Accepted Answer

Lay it flat with the jaw closed to relieve spring tension

Answer

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

Question 5

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

Accepted Answer

Safety glasses and rubber gloves

Answer

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