FAQ: How does a water hammer arrestor work?
What is a water hammer?
Water hammer is a phenomenon occurring in piping systems where valves control the flow of fluids. Water hammer occurs when a pressure surge propagates through a piping system. What happens is that a fluid in motion is forced to change its direction or to stop suddenly.
How do you recognize water hammer? It’s simple – you will hear a marked banging or knocking sound inside the pipes immediately after valve shut off.
Why do you need to stop water hammer?
Water hammer is not just annoying, but also dangerous for your pipes. Its long-term effects include:
- Pump and flow drainage system damage
- Ruptured pipes
- Damaging exterior equipment and infrastructure
- Accidents endangering health and safety
- Downtime and maintenance expenses
How can you prevent water hammer?
The choice of check valves has a significant influence on the occurrence of this phenomenon. Some types of valves can cause water to slam into the valve mechanism, causing pressure propagating throughout the piping system. So, best ways to prevent water hammer include:
- Using silent or spring-assisted check valves. These have an internal spring that moves the valve into closed position before flow reversal, thus reducing water hammer.
- The use of air chambers that work as a shock absorber for the water when it changes direction suddenly.
- Flushing old systems
- Installing pressure reducers and regulators in the supply line
- Reducing operating pressure
Some homeowners erroneously think that water hammer occurs due to air being trapped inside their pipes.
The opposite is true. Water hammer occurs when there is not enough air in your plumbing system. Water cannot be compressed; all of the pressure is transmitted to pipes as a mechanical force when a valve is closed. Air, quite differently, can be compressed and its presence will prevent the loud banging noise.
How does a water hammer arrestor work?
Water arrestors are generally equipped with a spring and a waterproof air bladder. Its role is to absorb the force of moving water.
They can be used successfully when the system of a pump and the shutoff valve are in the same line.
Unlike air chambers, water hammer arrestors do not require recharging.
They are used everywhere from homes to industrial facilities to prevent the damaging of expensive instruments.
Deciding who makes the best water hammer arrestor is not easy. This item is relatively simple and inexpensive and its success depends on installing it correctly. Again, selecting the right arrestor size also plays a role in solving the water hammer issue.
Many homeowners are looking for a whole house water hammer arrestor. This type of appliance can work as long as it absorbs excess water pressure.
If you have a serious water hammer issue, you need to install an arrestor at each fixture above the valve. Independently reducing the shock on the line is the most effective fix.
