What Is Water Hammer?
Water hammer occurs when water within pipes suddenly stops or changes direction, creating a shockwave that resonates through the pipework system. Imagine the pipes shaking, rattling, and rolling like a Buddy Holly tune! This phenomenon is also known as hydraulic shock.
Causes of Water Hammer:
Fast Closing Valves:
When valves (such as taps or ball valves) close abruptly, the sudden pressure increase inside the pipe generates water hammer.
Solution: Replace worn valves or adjust valve closing speed.
Airlocks:
Air chambers in the pipework act as cushions to prevent water hammer. If these chambers become waterlogged, the cushioning effect diminishes.
Solution: Replenish air supplies within the chambers by turning off the water supply, draining the pipes, and allowing air to refill the chambers.
Improperly Secured Pipework:
Loose pipes can amplify water hammer effects.
Solution: Secure pipes properly to minimize movement.
Faulty Ball or Float Valves:
Ball valves in cold water storage cisterns can cause water hammer due to float movement.
Solution: Attach an empty yogurt pot to the valve arm to dampen float effects. Use a high-pressure nozzle and consider upgrading to a Part 2 ball valve.
High Water Pressure:
Excessive water pressure (above 80 psi) increases the likelihood of water hammer.
Addressing Water Hammer:
Water Hammer Arrestor:
The easiest solution is installing a water hammer arrestor. These devices absorb pressure surges, preventing shockwaves.
South African Reference: Consult local plumbing suppliers for suitable arrestors.
Regular Maintenance:
Inspect valves, secure pipework, and maintain air chambers.
South African Tip: Regularly check ball valves in cisterns and ensure proper float behavior.
Remember, addressing water hammer promptly prevents more serious issues down the line. So, let’s keep those pipes harmonious! 🛠️💧
