Worked examples: old-pipe problems, start to finish
We invented every one of these examples. None describes a real job, customer or building. Each follows a common older-building problem from the first symptom to the fix, with the questions worth asking at each step, so you can spot the pattern in your own place.
Every example here is illustrative, built from common situations. None is a real job, customer or address.
- Hypothetical case: repeat backups in a downtown storefront
This is an invented example, not a real building or business. It shows how an owner could trace repeat backups in an older mixed-use building and fix the cause.
- Hypothetical case: a cast-iron leak under the house
This is an invented example, not a real job. It follows a common path from a faint sewer smell to a cracked cast-iron drain in a crawlspace.
- Hypothetical case: a buyer reviews an old sewer lateral
This is an invented example, not a real purchase. It shows how a buyer of an older house could use a sewer camera video to decide before closing.
- Hypothetical case: a bathroom remodel meets galvanized pipe
This is an invented example, not a real remodel. It shows how opening the walls of an older bathroom can change the plumbing plan, and why the plan belongs before demolition.
- Hypothetical case: a water heater swap with old connections
This is an invented example, not a real job. It shows what a routine water heater replacement in an older house can turn up, and how to handle the extra items.
