System Pressure: Consider the working pressure of your plumbing system. Higher-pressure systems may require larger arrestors with greater capacity to handle the increased energy from water hammer.

Again, these problems can have various causes. Sometimes, water can’t run through a TMV freely because parts of its valves are gummed up with debris or scale. Older valves might also suffer from corrosion which blocks them up. Or, a valve might not have been fitted correctly in the first place.

Flow Rate: Evaluate the maximum flow rate of your plumbing system to determine the size of the arrestor. Consider the fixtures, appliances, and peak water demands to ensure the arrestor can handle the expected flow.

A thermostatic mixing valve (TMV) bridges the hot water in your system and the water that comes out of taps or showers. It keeps your hot water system safe in a couple of ways, and can keep you safe, making it a crucial part of your home plumbing that your local plumber should always check.

Choosing the right size for a water hammer arrestor is crucial for ensuring optimal performance and preventing potential issues. Here are a few reasons why correct sizing is important:

When you turn on a tap or shower that connects to a TMV set-up, then the valve controls the release of hot water. Typically, it mixes hot and cold water together to reach a set temperature as dictated by its thermostat setting set by a plumber with a TMV licence. So, your water should never run so hot that it could scald or burnWhen all is well, the TMV works seamlessly. However, it might develop problems that prevent it from working as it should. What are the signs that your valve has a fault?

In some cases, a faulty TMV can also affect your cold tap. Here, you might find that this tap runs warm or hot rather than cold.

Noise Reduction: Water hammer can produce loud banging or knocking noises that can be disruptive and bothersome. A properly sized arrestor is designed to minimize these noises, providing a quieter and more comfortable environment.

Sometimes, the first sign of a TMV problem is a change in the way your water comes out of a tap. Typically, you see a reduction in flow or pressure here.

If a TMV valve stops working correctly, then you may notice that your hot water suddenly starts to run hotter than it should. If the valve can’t regulate temperature correctly, it might not be able to cool hot water down enough to make it safe.

Changes in water temperature have various causes. For example, the valve may be blocked or may have moved out of position. The thermostatic element might have stopped working or might have a problematic O-ring. Or, you might have a problem with water pressure or flow through the valve.

First, it allows your system to store water at a high enough temperature to keep bacteria at bay. However, it also regulates the temperature of the water that you use.

If you have problems with a TMV, then you sometimes see outward signs that all isn’t well. For example, water might seep out of parts of the valve; you may even see some water on the floor under it. This might indicate a faulty seal or a corrosion problem.

Pressure Absorption: An appropriately sized arrestor has the capacity to absorb and dissipate the energy generated by water hammer effectively. It helps maintain stable pressure levels and prevents excessive strain on the plumbing system.

Consulting a Plumbing Professional: Determining the correct size for a water hammer arrestor can be complex, as it involves various factors specific to your plumbing system. It is advisable to consult a plumbing professional who can assess your system, consider the relevant parameters, and recommend the appropriate size and type of arrestor.

For example, your water might start to run sluggishly and slowly all the time. You might struggle to get the tap to give out more than a trickle of water. Or, your water might switch between working normally and running at a reduced pressure or flow.

Water hammer arrestor size refers to the capacity of the device to absorb and control pressure surges caused by sudden flow changes in the plumbing system. It is typically measured in gallons per minute (GPM) or liters per minute (LPM) and represents the maximum flow rate that the arrestor can effectively handle.

Location: Different areas of the plumbing system may have varying flow rates and pressure characteristics. Assess the specific locations where water hammer is likely to occur and ensure the arrestor is appropriately sized for each location.

Pipe Diameter: The diameter of the pipes in your system also plays a role in sizing the arrestor. Larger pipe diameters may require larger arrestors to accommodate the increased water volume.

If you have concerns about a TMV, then you need expert help. Don’t try to fix these valves if you don’t know what you’re doing. They are too important a safety job to mess up.

However, excess heat isn’t the only sign of trouble here. Sometimes, a failing TMV makes the water too cold. Or, water may not run at the right temperature consistently. It may fluctuate between being hot and cold.

Considerations for Sizing Water Hammer Arrestors: When determining the appropriate size for a water hammer arrestor, the following factors should be considered:

System Protection: Correctly sized water hammer arrestors help protect the plumbing system from damage. By absorbing pressure surges, they reduce the stress on pipes, valves, fittings, and other components, preventing leaks, bursts, and premature failures.

Conclusion: Water hammer arrestor size is a critical aspect of their effectiveness in controlling pressure surges and preventing damage in plumbing systems. By understanding what is meant by water hammer arrestor size and considering factors such as flow rate, pipe diameter, system pressure, and location, you can ensure that your arrestors are correctly sized for optimal performance. Consulting with a plumbing professional will help you make informed decisions and ensure the long-term stability and reliability of your plumbing system.

Water hammer arrestors play a crucial role in mitigating the damaging effects of water hammer in plumbing systems. These devices absorb sudden pressure surges and help maintain the stability of the system. One key factor that influences the effectiveness of a water hammer arrestor is its size. In this blog post, we will explore what is meant by water hammer arrestor size, why it matters, and the important considerations to keep in mind when determining the appropriate size for your plumbing system.

If you have a TMV in your shower, then a faulty valve can make the shower drip even when it is off. Here, the valve may not be in the right position so it doesn’t shut water off effectively. Or, you may have a problem with the valve’s seals or cartridge.
