Journeyman Plumber ExamPlumbing Code and RegulationsMedium
A plumber is installing a water-supplied appliance in a new residential construction. The local jurisdiction follows the International Plumbing Code (IPC). What is the maximum length allowed for a flexible water connector supplying a fixture or appliance?
- A18 inches
- B36 inches
- C24 inches
- D30 inches
Show answer & explanationAnswer & explanation
Correct answer: B. 36 inches
The IPC limits the maximum length of a flexible water connector to 36 inches (3 feet). This restriction helps minimize the risk of kinks, damage, and excessive pressure drop, ensuring a reliable and safe connection.
Why the other options are wrong
- A. 18 inches is a common length for flexible connectors, but not the maximum allowed by code.
- C. 24 inches is also a common length, but still not the maximum permitted by the IPC.
- D. 30 inches is not the specified maximum length in the IPC for flexible water connectors.
Flexible Water Connector Max Length
The longest permissible length for a flexible supply line connecting a fixture or appliance to the rigid water piping.
- Prevents kinking and damage.
- Ensures proper water flow.
- Standardized by plumbing codes.
Memory trick: Flexible link, three feet long, keeps the water flow strong.
