An extremely important function of a TMV is if the supply of cold or hot water is lost, the water flow will shut down immediately, preventing scalding, burning and dangerous reactions from moving too quickly away from a too hot or too cold water stream resulting in injury.

As per the example used here, a standard 1/2″ supply line with water flowing at 1.8 m/s can generate a pressure rise of 29 kg/cm2 above the flow pressure itself. The resultant shock wave bounces back and forth within the supply line until it reaches a point of relief in a larger main where the velocity is much slower.

604.9 Water hammer: The flow velocity of the water distribution system shall be controlled to reduce the possibility of water hammer. A water-hammer arrestor shall be installed where quick-closing valves are utilized. Water-hammer arrestors shall be installed in accordance with the manufacturer’s instructions. Water-hammer arrestors shall conform to ASSE 1010. WATER-HAMMER ARRESTOR. A device utilized to absorb the pressure surge (water hammer) that occurs when water flow is suddenly stopped in a water supply system

As the valve is suddenly closed, the flowing water with its energy (as explained with the above formula) hits the valve, bounces back and collides with the approaching stream of water. The collision that happens in the pipeline triggers an enormous pressure spike in the pipeline to create this undesirable noise and shaking, called water hammering. (Think of a train engine applying a sudden brake causing the compartments to collide with each other).

In many industries including aged care facilities, installation and yearly certification of thermostatic valves is a compliance and legal requirement. The TMV Testing Requirements according to the Australian Standard (AS4032.3) states that a TMV shall be inspected and maintained at least every 12 months and the replacement of thermostat and o-rings every 5 years. NSW Health Act 2010 requires hospitals to test TMV’s every 6 months to ensure scald prevention.

The picture shown here illustrates how a Water Hammer Arrestor functions. This simple device can effectively control the undesirable effects of water hammering and is widely being used in the industry. The operations of the WHA can be compared to the working of a shock absorber used in a motorbike.

Due to the potential for serious burns at 60°C, there is a compliance requirement to ensure a safer temperature at the tap. AS3498 is the standard used for TMV installation and testing and it requires the delivery of hot water for personal hygiene to be delivered from the tap at a maximum of 50°C to prevent burns. For early childhood centres, schools, aged care, corporate facilities or other specific businesses with customers at risk like hairdressers or beauty salons the maximum temperature at the tap must be 45°C.

The pressure shock wave, with its energy hits and pushes the piston inside the WHA upwards, compressing the pre-charged air and loses its energy. Once the effect of the peak pressure shock wave is absorbed, the piston gradually returns back to its original rest position. This tendency of the piston inside the water hammer arrestor to revert to its original position is the reason behind the working of a water hammer arrestor.

Thermostatic Mixing Valves are used to protect people especially customers, the elderly, people with a disabilities and young children, from the scalding effects of water that is too hot. They also reduce the risk of disease spreading in your water supply as hot and cold is mixed at the right temperature just prior to coming out of the tap.

When the valve is opened, the water starts flowing in the pipeline. Here, we can measure the kinetic energy of the flowing water by using the formula: KE = (m*v²)/2; where m is mass, v is velocity of the water.
