Sample interview questions: How do you ensure that plumbing systems are designed to be resistant to water hammer or hydraulic shock?
Sample answer:
-
Containment and Isolation:
-
Ensure that the plumbing system is designed with air chambers, expansion tanks, or surge arrestors to absorb and dissipate pressure surges caused by water hammer.
-
Locate valves and other isolation devices strategically to allow for the isolation of specific sections of the plumbing system during repairs or maintenance, minimizing the impact of water hammer on the rest of the system.
-
Proper Sizing and Installation:
-
Specify and install pipes with adequate diameters to minimize water velocity and reduce the risk of pressure surges.
- Ensure that pipes are properly supported and secured to prevent movement and vibration, which can contribute to water hammer.
-
Use flexible connectors or couplings where pipes change direction or terminate to absorb vibrations and reduce stress on joints.
-
Gradient and Slope:
-
Design the plumbing system with proper gradients and slopes to facilitate the efficient flow of water and prevent the accumulation of air pockets that can cause knocking sounds.
-
Ensure that drainpipes have adequate坡度, … Read full answer
