  1. What is hydrostatic testing in plumbing?

    Answer: Pressure testing a plumbing system by filling it with water and applying specified pressure to check for leaks

    Hydrostatic testing fills the plumbing system with water and pressurizes it to a specified level (typically 1.5 times working pressure) to detect any leaks before walls are closed.

  2. What is a reciprocating saw used for in plumbing work?

    Answer: Cutting pipe, wall materials, and old fixtures in tight spaces during remodeling

    A reciprocating saw is used in plumbing remodels to cut out old pipe sections, cut access holes, and remove fixtures in areas where circular saws cannot reach.

  3. What is the purpose of a press fitting system (like ProPress) in copper plumbing?

    Answer: To create permanent crimped connections without soldering or open flame

    Press fittings (ProPress) use a specialized jaws tool to mechanically crimp fittings onto copper pipe, creating a permanent connection without torch, solder, or flame — faster and safer than sweating.

  4. What tool is used to cut large-diameter cast iron pipe in the field?

    Answer: Snap cutter (soil pipe cutter) or angle grinder with cutting disc

    A snap cutter (soil pipe cutter) uses hardened cutting wheels on a chain to score around large cast iron pipe and snap it cleanly, or an angle grinder with a cutting disc can be used.

  5. What is the purpose of a manometer in plumbing work?

    Answer: To measure gas or water pressure in a system

    A manometer measures pressure in gas or water systems, helping verify that supply pressure is within the correct range for proper appliance operation.

  6. What is the purpose of applying joint compound (pipe dope) to threaded connections?

    Answer: To lubricate threads for easier assembly and create a leak-tight seal on threaded connections

    Pipe dope (thread sealant compound) lubricates threads to prevent galling during assembly and seals the threaded connection against leaks, suitable for both water and gas.
