Which test is used to identify defects in the drainage system?

• A. Peppermint test
• B. Hydrostatic test
• C. Smoke test
• D. Pressure test

Answer: (A)

Identifying defects in a drainage system relies on a test that makes hidden leaks visible. A smoke test achieves this by sealing the drainage system and introducing non-toxic smoke into the piping. If there are cracks, loose joints, improper connections, or vent issues, the smoke escapes and becomes visible at access points such as cleanouts, vent stacks, or floor penetrations. This allows you to pinpoint exact locations where repairs are needed, even when leaks aren’t obvious from the outside. Hydrostatic or pressure tests, by contrast, involve filling piping with water or air under pressure to check for leaks, which is common for water-supply lines or when testing assemblies that must hold pressure. They’re not as effective for revealing issues in drainage systems that vent to the atmosphere, which is where a smoke test shines. Peppermint test isn’t a standard, reliable method used in professional drainage testing, so it wouldn’t provide dependable indications of defects.
