Field Diagnostics: Reasoning to the Likely Cause

Lesson

Fault finding: reasoning to the likely cause

A method for diagnostic questions, plus the recurring symptom patterns in plumbing and heating.

Turn a fault symptom into the next useful check

Separate what the customer reports from what the scenario has established. For no hot water, no heating or low pressure, list what remains possible and choose a check that helps distinguish those causes. Do not replace missing evidence with a familiar fault pattern.

Try the free plumbing diagnostic questions, then revisit the cold-water or central-heating notes behind a missed answer. Use each explanation to identify why an attractive alternative was not justified by the information given.
